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:

[armadeus]$ tftp -g -r myFirmwareFile myServerIpAddress

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

[armadeus]$ flash_eraseall /dev/mtd2/

Then your FPGA .bit file can be written

[armadeus]$ nandwrite -p /dev/mtd2 myFirmwareFile

That's all
