Uboot FPGA firmware update from Linux

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

• Once done, the U-Boot Firmware partition has to be erased:

 # flash_eraseall /dev/mtd2/

• Then your FPGA .bit file can be written:

 # nandwrite -p /dev/mtd2 my_firmware.bit

That's all !
