KNEO PI boot problem
During the process of firmware updating, I tried to execute the following command on U-BOOT:
setenv fastboot_bootcmd 'echo ok';fastboot -l 0xA00000 usb 1
But as the command does not succeded, I tried to change usb1 to usb0:
setenv fastboot_bootcmd 'echo ok';fastboot -l 0xA00000 usb 0
After that the board apparently stucked on boot and I am unable to boot again, either from SD Card or Nand.
