Hi, I am using a very old version of uboot the following is the modification I made to disable command line access in uboot
1) disable all autoboot options like AUTOBOOT_KEYED, AUTOBOOT_PROMPT, AUTOBOOT_DELAY_STR, AUTOBOOT_STOP_STR, AUTOBOOT_KEYED_CTRLC 2) In common/autoboot.c file I am unconditionally calling disable_ctrlc(1) before the call to run_command_list(s, -1, 0) in the function autoboot_command() Can someone confirm directly calling disable_ctrlc(1) is OK and that no other key combination will stop the execution? I just don't want users to modify any thing on the bootloader prompt and so disabling the access completely to cmd prompt. Regards Fariya
