Press a key to enter U-Boot autoboot

Configure network parameters (statically or with DHCP, see relevant sections)

Start the TFTP server on the host machine

Place the desired image in the host PC's TFTP root directory

(for example, /tftpboot/uImage_new.img)

From U-Boot console, download the image to RAM (here we use address 0x0) with

TFTP client:

> tftp 0x0 uImage_new.img

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

Reboot the evaluation board
