1.
Press a key to enter U-Boot autoboot
2.
Configure network parameters (statically or with DHCP, see relevant sections)
3.
Start the TFTP server on the host machine
4.
Place the desired image in the host PC's TFTP root directory
(for example, /tftpboot/uImage_new.img)
5.
From U-Boot console, download the image to RAM (here we use address 0x0) with
TFTP client:
> tftp 0x0 uImage_new.img
6.
Erase the specified kernel area on serial NOR:
> erase 0:5-31
Write the image on serial NOR (you need to know the image size). In this example we
copied 1663104 bytes (0x196080 in hexadecimal) to the start of the kernel area on
serial NOR (0xF8050000 in hexadecimal):
> cp.b 0x0 0xF8050000 0x196080
7.
Reboot the evaluation board
