With an available network connection, U-Boot can load images quickly and easily via TFTP.
We’ll start off with a terminal connected to the board and sitting at the U-Boot prompt.
kvim# tftp 1080000 u-boot.bin
You might also need to clean up the old U-Boot environment value stored in the
envpartition, and then save it as a new value:
resetbutton to boot from the new bootloader:
1 kvim# reset
Load image into memory, then run
bootm to boot from memory:
kvim# tftp 1080000 boot.img
Only for Android.
Download and run Linux:
kvim# tftp 1080000 zImage
Only for Ubuntu.
You need to write a DTB first!
