The U-Boot FPGA firmware can be updated by means of U-Boot (Target_Software_Installation#FPGA_firmware_installation) or directly from Linux as described herewith.
Under Linux:
- At first download your FPGA firmware:
# tftp -g -r my_firmware.bit 192.168.0.2
- Then, determine which partition in the flash is the firmware partition:
# cat /proc/mtd dev: size erasesize name mtd0: 00100000 00020000 "u-boot" mtd1: 00080000 00020000 "env" mtd2: 00080000 00020000 "env2" mtd3: 00100000 00020000 "firmware" mtd4: 00080000 00020000 "dtb" mtd5: 00080000 00020000 "splash" mtd6: 00800000 00020000 "kernel" mtd7: 1f400000 00020000 "rootfs"
The example above is taken from an APF51 running Armadeus version 5.2 and we can see that mtd3 is the firmware partition. If yours is different, then replace mtd3 by what you found out to be the right one in the following commands.
- Once done, the U-Boot Firmware partition has to be erased:
# flash_eraseall /dev/mtd3/
- Then your FPGA .bit file can be written:
# nandwrite -p /dev/mtd3 my_firmware.bit
That's all !
