Hello
I have custom board built using AM3358, Do not have any documentation.
Before experimenting with this board, how can I backup nand to tftp or sd card from u-boot (Using UART Console).
I cannot login to Linux cause this board is custom do not have any documentation on this.
Need help with backup nand and to
copy only "0x000000780000-0x000020000000 : "File System"" from nand to sd card or to pc using tftp (from U-boot)
