Simple BSP for the TX3904 simulator built into gdb.

Simulator Invocation

The following is how the simulator is invoked.

target sim –board=jmr3904

GDB must be configured with a target like "tx39-rtems". Otherwise, the simulator will not be built for the correct instruction and peripheral set.

Simulator Information

The simulated system clock counts instructions. Setting the clock source to "clock" and the divider to 1 results in the timer directly counting the number of instructions executed.

Status

• hello.exe locks up while running the global destructors. This almost has to be a linkcmds issue.
• Workaround: bspclean.c actually explicits invokes _sys_exit() BEFORE letting the global destructors run.
• There is a clock tick device driver which has not been calibrated.
• There is no timer device driver.
