Hi everyone, sorry for my pool english,
I break the emmc partition by fdisk, i tried to flash ras.bin from tftp, but it's not working...
So I think the gpt partition must be restored at first, and I found a command ATUG from serial port
ATUG upgrade GPT partition table on GMMC (gpt_main1.bin, gpt_backup1.bin)
but where I can find the gpt_main1.bin?
Here is all the command under U-boot
ATBT x bnock0 wrmteenable (1=enable, 0=disable)
