I'll need to review procedure for doing that but I have enough examples to do so. 2011-02-02T16:40:30 OK. 2011-02-02T16:40:37 This is good info. 2011-02-02T16:40:39 My test code on the ftp site should have a RAM disk 2011-02-02T16:40:57 All you need to do is look for the difference then we can from there. 2011-02-02T16:40:58 I think I've pulled that down so I'll use that. 2011-02-02T16:41:13 Excellent - I'll try to get as much info as I can back to you. 2011-02-02T16:41:17 After that and if it is the flash driver we can turn its trace on and take a look. 2011-02-02T16:41:36 OK. Thanks for the suggestions. Great ideas. 2011-02-02T16:41:57 I can work through that later today and tomorrow. 2011-02-02T16:41:59 This will let us focus on the specific area without too much trouble. 2011-02-02T16:42:13 Excellent. Please keep me update on your progress. 2011-02-02T16:42:36 I certainly will. 2011-02-02T16:48:23 kiwichris: One problem. The ram disk will not survive a reboot. Where the problem occurs is after directories/files have been added to rfs from ftp and then the system reboots. Any thoughts on that? 2011-02-02T16:49:23 Ah ok. So the RFS sees the disk as ok until the reboot ? 2011-02-02T16:51:10 Yes. Interestingly, if I create directores from the shell, all is well after the reboot. But, if I create directorires and add files via ftp, it is not. One thought I just had - I'm transferring two directories that contain multiple files. Let me try some tests with just empty directories and ftp. 2011-02-02T16:51:37 Ok. 2011-02-02T16:52:12 I would check the calls to mknod in each case to make sure ftp and shell are the same. 2011-02-02T16:52:46 I did check the mkdir calls - they are the same. I think that just drops into the mknod call. 2011-02-02T16:53:39 If this all checks out we can dump the disk contents using dd. 2011-02-02T16:53:55 before and after the reboot. 2011-02-02T16:53:56 OK. 2011-02-02T16:54:05 Do you have an NFS disk mounted ? 2011-02-02T16:54:19 No. 2011-02-02T16:54:23 Very useful when doing this stuff. 2011-02-02T16:54:42 I could probably get one up and running. 2011-02-02T16:55:07 It may pay because you can then dd the whole disk to a host where you can byte compare 2011-02-02T16:55:27 I'll look into that. 2011-02-02T16:55:58 If you do a before reboot and after reboot that removes large parts of the code 2011-02-02T16:56:06 if the dump is the same 2011-02-02T16:56:24 If it is not the same then we have a better idea on the possible areas 2011-02-02T16:56:25 I did the rfsdebug dumps. I think I sent you the info that the directory inode for one of my directores did not have any mode info after reboot. 2011-02-02T16:56:41 *** dr__house has quit IRC 2011-02-02T16:57:10 But, I'll try to narrow it down. Right now it's not a fair test between shell and ftp b/c shell is only creating directories. 2011-02-02T16:57:53 ftp creates the directory - sends file data to the directory, then creates the next directory and sends the file data to that directory. I'm using filezilla. 2011-02-02T16:57:57 Agreed because of all the mappings the same nodes and blocks would need to be used to be the same. 2011-02-02T16:58:35 Let me start small and work my way up. 2011-02-02T16:59:23 be back in a while to start this tests.

I am writing Ada ... LOL 2011-02-02T17:26:35 just on the phone 2011-02-02T17:32:31 i think this is all driven by automake and this would point to Ralf giving us a lead on what we can do. 2011-02-02T17:33:05 Writing Ada huh. 2011-02-02T17:33:10 yep. we have had discussions in the past. 2011-02-02T17:33:35 Fixing Ada even.. I am writing custom RTEMS Shell commands in Ada. 2011-02-02T17:34:24 I needed an Ada implementation of getopt_r. Found a getopt implementation on the net dated 1999. Went to use it and managed to find a bug. If you do something like "cmd -c16 -d", it indexes off the end of the string 2011-02-02T17:37:51 But that would be ok in Ada because you would get an exception and recover !! 2011-02-02T17:38:04 theoretically 2011-02-02T17:40:38 kiwichris: I'm back. Performed my first test with just creating directories via ftp. Same results. I am going to dig back in and ensure that the mknode calls do look the same. I can do this with the debugger, I suspect. 2011-02-02T17:41:11 thanks for looking at the chris.. 2011-02-02T17:42:56 *** DrJoel has quit IRC 2011-02-02T17:43:23 bswimley, I just had a thought which might be a source of problems. 2011-02-02T17:43:54 The shell supports a proper environment which is using task variables. I wonder what the ftp server is using. 2011-02-02T17:44:34 They both call rtems_libio_set_private_env 2011-02-02T17:44:51 Where is the ftpd code ? 2011-02-02T17:45:19 Is it under cpukit in ftpd ? 2011-02-02T17:45:23 I'm using a modified version of it, but it is in cpukit\ftpd. 2011-02-02T17:45:25 Yes. 2011-02-02T17:46:02 "session" calls rtems_libio_set_private_env 2011-02-02T17:46:19 I don't know enough about this unfortunately. 2011-02-02T17:46:49 That's sort of what I suspected over the past couple of days. 2011-02-02T17:47:37 be back in a bit. I need to go be a child shuttle service again. 2011-02-02T17:47:44 ok 2011-02-02T18:38:33 kiwichris: I'm back. 2011-02-02T18:39:21 still here 2011-02-02T18:39:59 Got your email. IIRC, when I created the inode via the shell, upon reboot it came back as being used and had proper mode info. 2011-02-02T18:40:31 I can rerun the test if need be. 2011-02-02T18:41:08 In the email your sent how did you get the inode number for the ftpd run ? 2011-02-02T18:41:38 Turned on trace and figured out which one it was. 2011-02-02T18:42:29 I may have used the debugger as well. 2011-02-02T18:42:40 Was fda the top of the RFS volume ? 2011-02-02T18:44:38 I *think* yes. /dev/fdda was mounted at /mnt/fla 2011-02-02T18:44:56 I also have /mnt/sd. 2011-02-02T18:45:05 For the sd card. 2011-02-02T18:45:12 ok.

The current RFS is a little slow deleting all when over 500 files. 2011-02-02T19:17:01 Let me go back to my ftp transfer where I'm transferring a bunch of files and repeat my tests. 2011-02-02T19:17:16 Ok 2011-02-02T19:17:51 Oh, what should I see with hexdump after I do an fderase? All FFs? 2011-02-02T19:18:10 I think so. 2011-02-02T19:18:39 I was not seeing that, but if I did a dm of the start of my flash area, I was seeing the ffs. 2011-02-02T19:19:11 Ah the real view and the file view may not be the same. 2011-02-02T19:19:25 The /dev/fdda is via the flash driver 2011-02-02T19:20:12 Oh boy, now I don't see erased in my dm "real view" either. 2011-02-02T19:22:10 I've got to get going. I will repeat these tests and let you know the results later. 2011-02-02T19:22:26 Great. 2011-02-02T19:30:26 *** methril_ has joined #rtems 2011-02-02T19:32:39 *** methril has quit IRC 2011-02-02T20:05:49 *** kiwichris has quit IRC 2011-02-02T20:13:44 *** bswimley has quit IRC 2011-02-02T20:33:24 *** bswimley has joined #rtems 2011-02-02T22:48:05 *** antgreen has quit IRC 2011-02-02T23:34:06 *** dr__house` has joined #rtems 2011-02-02T23:34:06 *** dr__house` has joined #rtems 2011-02-02T23:36:50 *** dr__house has quit IRC 2011-02-02T23:43:14 *** dr__house` has quit IRC 2011-02-03T00:06:09 *** projectgus has quit IRC 2011-02-03T00:37:48 morning 2011-02-03T02:11:26 *** sebhub has joined #rtems 2011-02-03T02:11:41 good morning 2011-02-03T04:42:27 morning 2011-02-03T04:43:24 *** lcpfnyvc has quit IRC 2011-02-03T04:44:57 *** lcpfnyvc has joined #rtems 2011-02-03T06:42:47 *** antgreen has joined #rtems 2011-02-03T07:02:14 *** pradeepchhetri has joined #rtems 2011-02-03T07:03:08 *** pradeepchhetri has left #rtems 2011-02-03T07:38:55 *** antgreen has quit IRC 2011-02-03T08:04:35 *** antgreen has joined #rtems 2011-02-03T08:25:08 *** antgreen has quit IRC 2011-02-03T08:41:54 *** antgreen has joined #rtems 2011-02-03T08:43:47 *** dr__house has joined #rtems 2011-02-03T09:13:42 *** DrJoel has joined #rtems 2011-02-03T09:13:42 *** ChanServ sets mode: +o DrJoel 2011-02-03T09:14:07 hi DrJoel 2011-02-03T09:14:21 hey peerst 2011-02-03T09:14:58 I'm in contact with the bermiz people 2011-02-03T09:15:33 cool 2011-02-03T09:15:36 brb 2011-02-03T09:15:37 actually it looks like its just one person I think 2011-02-03T09:18:02 does bermiz fit into your vision? 2011-02-03T09:18:50 it might, depending they are interested in having a byte code engine as backend 2011-02-03T09:19:51 interested enought that they would put the effort of mentoring in 2011-02-03T09:19:59 do they already have a byte code generator? or interpreter? is there a standard to base it on? 2011-02-03T09:20:25 no they only have a ansi-c generator 2011-02-03T09:20:41 and there is no standard 2011-02-03T09:21:16 ouch 2011-02-03T09:21:40 DrJoel: Hello 2011-02-03T09:21:42 that sounds like too much work for GSoC. With no spec, it is hard to do it. 2011-02-03T09:21:46 the vendors have proprietary solutions 2011-02-03T09:21:50 hey kristianpaul 2011-02-03T09:22:29 peerst: I can understand that. Can the bermiz person define a byte code set? If they could do the generation side and the student an interpreter, then it is probably doable 2011-02-03T09:22:38 Are you aware of SDR projects wich uses rtems as base, and relesed the source code to public? 2011-02-03T09:22:50 what's SDR? 2011-02-03T09:23:21 Sofwatre Defined Radio 2011-02-03T09:23:27 Software** 2011-02-03T09:23:46 I knew that.. drew a blank. I think I know a couple of projects but none are open source 2011-02-03T09:24:00 GNSS to be more exactly 2011-02-03T09:24:11 DrJoel: they would have a student also, two students ... I could think of defining the byte code set with the beremiz person and one student implementing the backend (mentored by him) and one implementing the interpreter in rtems mentored by me. 2011-02-03T09:24:20 ok 2011-02-03T09:24:50 with a lot of ifs that have to be in place before 2011-02-03T09:25:55 if my customer is interested enough (because I personally dont care about IEC 61131 if they dont need it) and if the bermiz person wants to put effort in 2011-02-03T09:26:27 Not to be selfish but I don't see giving two RTEMS GSoC students to this as a project. (assuming we get accepted at all this year) If they apply and get accepted, then it may make sense to use an RTEMS slot (assuming interested student) to do byte code interpreter 2011-02-03T09:26:34 DrJoel: btw his nick is edouard_t her in irc, in case he shows up 2011-02-03T09:26:38 hold on.. getting errors from xchat.. need to restart 2011-02-03T09:26:43 *** DrJoel has quit IRC 2011-02-03T09:26:57 *** DrJoel has joined #rtems 2011-02-03T09:26:57 *** ChanServ sets mode: +o DrJoel 2011-02-03T09:27:16 somehow it was trying to play a sound that didn't exist after the OS upgrade. :( 2011-02-03T09:31:49 so you got to listen to john cage 2011-02-03T09:32:36 I was only assuming one student from GSoc on the RTEMS side 2011-02-03T09:32:40 that would have nicer.. instead I got a popup box about a missing .wav file everytime a message was posted. 2011-02-03T09:33:11 beremiz have to have their own GSoC student 2011-02-03T09:33:39 very important information the popup box ;-) 2011-02-03T09:34:16 Is the bermiz person in a position to write the byte code generator if (worst case) we have a student and there is no other support? 2011-02-03T09:34:50 Yep on beremiz having student. Need specification for byte code first as prereq for defining either project 2011-02-03T09:34:56 if there is sufficient funding from my customer I might write the generator myself ... or a new compiler 2011-02-03T09:35:08 that would be good 2011-02-03T09:35:34 would probably write a new compiler in javascript running in the browser 2011-02-03T09:35:44 uploading the byte code 2011-02-03T09:36:06 because: no installable tools to support at the end users site 2011-02-03T09:36:44 that makes sense. Would that be an extension to beremiz since they have the GUI tools from what I recall seeing 2011-02-03T09:37:10 but this would probably mean that there will be IEC 61131 support without GSoC student needs 2011-02-03T09:37:13 kind of 2011-02-03T09:37:32 there are two ascii languages that the graphical tools can output 2011-02-03T09:37:41 these languages are part of the standard 2011-02-03T09:38:07 if you can compile one or both of them to byte code you can work with any toolchain 2011-02-03T09:38:53 so you could use the beremiz toolchain for graphics or a commercial one 2011-02-03T09:38:59 ahhh... so it would work with any toolchain 2011-02-03T09:39:05 yep 2011-02-03T09:40:16 if I would build upon the bermiz stuff I would integrate the compiler itself into RTEMS since thats another way you dont need to support any installable tools 2011-02-03T09:40:24 just download the source code 2011-02-03T09:40:32 and it runs 2011-02-03T09:41:35 another possibility for a GSoC student would be to integrate their generated ansi-c 2011-02-03T09:41:58 there is some runtime work also to be done, talking to a visualization tool outside etc 2011-02-03T09:42:33 when there is a clean interface this ansi-c code can be replaced by a byte code interpreter later 2011-02-03T09:43:12 this would be a very managable amount of work for one student 2011-02-03T09:43:38 so first step (for a student this summer) would be support beremiz ansi-C output on RTEMS? 2011-02-03T09:43:43 which wouldn't need cooperation by beremiz 2011-02-03T09:43:51 yes 2011-02-03T09:44:07 No but having them as a co-mentor on the project would make getting it done easier 2011-02-03T09:44:44 yes but for this co-mentoring a single student would be enough 2011-02-03T09:44:46 If you want to define that as a project, how it would be tested, etc. go ahead and add it to the Open Projects list and add a project page for it. I am guessing you and the Beremiz guy would co-mentor 2011-02-03T09:45:29 I will but currently working against a deadly deadline 2011-02-03T09:45:51 until when do we need the project definition 2011-02-03T09:48:30 I think late feb is when we have to have the org application in. So anytime this month should be great 2011-02-03T09:48:40 puh 2011-02-03T09:49:16 deadline is end of february 2011-02-03T09:49:27 my deadline 2011-02-03T09:51:26 add at least a placeholder and a paragraph/URLs in the page. If no one spots it before the end of Feb and expresses interest, then that's more than enough. :D 2011-02-03T09:52:34 :-) 2011-02-03T09:59:28 *** bswimley has joined #rtems 2011-02-03T10:44:48 *** sebhub has quit IRC 2011-02-03T11:15:07 *** antgreen` has joined #rtems 2011-02-03T11:59:45 *** antgreen has quit IRC 2011-02-03T11:59:46 *** antgreen` has quit IRC 2011-02-03T12:13:07 *** antgreen has joined #rtems 2011-02-03T12:35:23 *** madrazr has joined #rtems 2011-02-03T12:35:28 *** madrazr has joined #rtems 2011-02-03T12:49:59 *** madrazr has quit IRC 2011-02-03T12:52:16 *** dr__house has quit IRC 2011-02-03T16:15:54 *** projectgus has joined #rtems 2011-02-03T16:42:08 *** DrJoel has quit IRC 2011-02-03T17:53:34 *** bswimley has quit IRC 2011-02-03T21:06:59 IEC 61131 front-end for parrot? 2011-02-04T00:04:20 *** projectgus has left #rtems 2011-02-04T00:40:33 morning 2011-02-04T01:11:15 hi anyone had any problems getting cexp compiled on a 64-bit linux (rhel 5.5 ) machine? 2011-02-04T01:22:08 agrier: parrot might be a interesting byte code for IEC 61131 2011-02-04T01:22:37 but how far is parrot integration in rtems? 2011-02-04T01:23:24 and one thing might be that IEC 61131 could be probably supported by a much more lightweight interpreter 2011-02-04T01:54:26 *** methril_ has quit IRC 2011-02-04T01:54:35 *** methril__ has joined #rtems 2011-02-04T02:10:23 *** sebhub has joined #rtems 2011-02-04T02:10:43 good morning 2011-02-04T02:22:22 *** peerst has quit IRC 2011-02-04T06:46:16 *** peerst has joined #rtems 2011-02-04T06:46:20 hi 2011-02-04T06:46:48 hi 2011-02-04T08:41:01 *** lcpfnyvc has quit IRC 2011-02-04T08:44:46 *** lcpfnyvc has joined #rtems 2011-02-04T08:53:33 *** antgreen has quit IRC 2011-02-04T09:10:35 *** antgreen has joined #rtems 2011-02-04T09:51:09 *** dr__house has joined #rtems 2011-02-04T09:51:09 *** dr__house has joined #rtems 2011-02-04T10:13:53 *** bswimley has joined #rtems 2011-02-04T10:54:41 *** dr__house has quit IRC 2011-02-04T11:06:52 *** sebhub has quit IRC 2011-02-04T12:33:14 *** madrazr1 has joined #rtems 2011-02-04T13:25:38 *** madrazr1 is now known as madrazr 2011-02-04T13:25:49 *** madrazr has joined #rtems 2011-02-04T15:54:25 *** madrazr has quit IRC 2011-02-04T15:55:52 *** madrazr has joined #rtems 2011-02-04T16:06:17 *** madrazr has quit IRC 2011-02-04T17:18:01 *** Nuzoo has joined #rtems 2011-02-04T17:18:10 hello 2011-02-04T17:20:20 *** Nuzoo has left #rtems 2011-02-04T18:07:10 *** bswimley has quit IRC 2011-02-05T00:12:36 I thought parrot for RTEMS was done last year for GSoC 2011-02-05T00:12:49 (very long term turnaround) 2011-02-05T05:35:23 *** lcpfnyvc has quit IRC 2011-02-05T05:36:07 *** lcpfnyvc has joined #rtems 2011-02-05T09:39:16 *** dr__house has joined #rtems 2011-02-05T09:39:16 *** dr__house has joined #rtems 2011-02-05T12:31:50 *** madrazr1 has joined #rtems 2011-02-05T12:34:20 *** madrazr1 is now known as madrazr 2011-02-05T12:34:30 *** madrazr has joined #rtems 2011-02-05T15:01:57 *** madrazr has quit IRC 2011-02-05T15:17:01 *** madrazr has joined #rtems 2011-02-05T15:39:43 *** dr__house has quit IRC 2011-02-05T16:27:14 *** madrazr has quit IRC 2011-02-05T22:29:14 *** kristianpaul has quit IRC 2011-02-05T22:35:06 *** kristianpaul has joined #rtems 2011-02-06T01:54:46 *** methril_ has joined #rtems 2011-02-06T01:57:14 *** methril__ has quit IRC 2011-02-06T07:35:52 *** dr__house has joined #rtems 2011-02-06T07:35:52 *** dr__house has joined #rtems 2011-02-06T10:04:02 *** lakshay90 has joined #rtems 2011-02-06T10:06:14 *** kristianpaul has quit IRC 2011-02-06T10:15:17 *** kristianpaul has joined #rtems 2011-02-06T10:15:18 *** kristianpaul has joined #rtems 2011-02-06T10:45:43 *** dr__house has quit IRC 2011-02-06T10:49:31 *** ssachdeva has joined #rtems 2011-02-06T11:02:32 *** lakshay90 has quit IRC 2011-02-06T12:31:39 *** lakshay90 has joined #rtems 2011-02-06T12:34:36 *** madrazr has joined #rtems 2011-02-06T15:11:21 *** ssachdeva has left #rtems 2011-02-06T15:53:39 *** lakshay90 has quit IRC 2011-02-06T16:06:50 *** dr__house has joined #rtems 2011-02-06T16:06:50 *** dr__house has joined #rtems 2011-02-06T16:47:22 *** projectgus has joined #rtems 2011-02-06T17:13:49 *** dr__house has quit IRC 2011-02-06T17:22:04 *** madrazr has quit IRC 2011-02-06T19:16:05 *** dr__house has joined #rtems 2011-02-06T19:16:05 *** dr__house has joined #rtems 2011-02-06T22:32:58 *** dr__house has quit IRC
