I am using the imx6q sabresd board i flash the android9 image for the board and i set the uboot environmental variable
"setenv bootdelay 0" and saveenv, reset, after doing this i am able to set the uboot environmental variable by pressing the enter key but i am expecting it should not allow me to enter in uboot mode, please have a look for the below logs,
can any one help what could be the reason for this.
Hit any key to stop autoboot: 0
Environment size: 320/8188 bytes
Thanks in Adavance and Best Regards
Hello Nandish SG,
If I understand correctly you wish to block access to the uboot console, so it won’t be accessible.
Besides reducing the boot delay to zero you may also enable the “silent” mode. However, if you want to really secure your application it would be better to set a password to access uboot or enable other security measures.
I hope this helps!
Thanks for your quick reply and what you understand is correct "wish to block access to the uboot console, so it won’t be accessible", so i set theand even in the boot args it show autoboot is zero so why it enter to the uboot mode if i press any key, it should not be enter uboot mode right,
so if not going to the uboot mode then no need to set the any password to access the uboot.
can you please reply to me how to enable the “silent” mode.
Thanks and Best Regards
