use kermit upgrade firmware failed
HI all, I am trying to upgrade ATMEL AT91RM9200 board by using Kermit.
From Uboot, I send loadb 20400000, then from kermit send my firmware to this board. But after reboot, it stops at:
/bin/sh: can't access tty; job control turned off
#
if use ps to check Linux process loaded, I get nothing.
But I can use tftp from Uboot load the same firmware to board, run everything successfully.
Below is my screen capture, any help will be appreciated.
