Hi Ti,

I set the uboot env bootdelay=0, I can't enter uboot console to input fastboot 0. How I enter fastboot?

if ctrl-c doesnt work,

The boot order in general is SD first((MMC0) , eMMC(MMC1) second. So,
1) update u-boot.img and MLO with bootdelay=3 in a SDcard and insert SD card on the J6 EVM and boot till command prompt
2) "mmc dev 1"; "mmc rescan" ; "mmc erase 0 0x400" { This should erase emmc blocks}
3) update with fastboot images again with correct u-boot ( without boot_delay=0 )
