Overview

Evaluation board for this BSP:

  • Cyclone V SoC FPGA Development Kit
  • DK-DEV-5CSXC6N/ES-0L

RTC

The evaluation board contains a DS1339C RTC connected to I2C0. To use it you have to set the following options:

#define CONFIGURE_APPLICATION_NEEDS_RTC_DRIVER
#define CONFIGURE_BSP_PREREQUISITE_DRIVERS I2C_DRIVER_TABLE_ENTRY

Additional there has to be one free file descriptor to access the i2c. Set the CONFIGURE_MAXIMUM_FILE_DESCRIPTORS accordingly.

Network

The default PHY address can be overwritten by the application. To do this, the drv_ctrl pointer of the rtems_bsdnet_ifconfig structure should point to a dwmac_ifconfig_drv_ctrl object with the appropriate settings before the rtems_bsdnet_initialize_network() is called. E.g.:

#include <libchip/dwmac.h>
#include <bsp.h>
static dwmac_ifconfig_drv_ctrl drv_ctrl = {
.phy_addr = 1
};

...

static struct rtems_bsdnet_ifconfig some_ifconfig = {
.name = RTEMS_BSP_NETWORK_DRIVER_NAME,
.attach = RTEMS_BSP_NETWORK_DRIVER_ATTACH,
.drv_ctrl = &drv_ctrl
};

...

rtems_bsdnet_initialize_network();

If drv_ctrl is the NULL pointer, default values will be used instead.
