[U-Boot] U-boot : bootdelay: require your help

[Phani]

Hi,



I am using a MPC8572 costume board. I am using U-boot as the boot loader. I accidently made the bootdelay to 0 and I have the valid kernel , rootfs in flash. The bootargs is "root=/dev/ram rw console=ttyS0,115200".



So I am not able to stop booting the board at the u-boot prompt. Can you pls let me know how can I access/change the uboot params from the Linux user application.



Sorry if it's a repost..!!



Thanks you all for the help ..!!

Regards,
Phaniram.K

You can check if your configuration includes CONFIG_ZERO_BOOTDELAY_CHECK
(see doc/README.autoboot).  In this case you should still be able to
stop the boot process by continuously hitting a key during startup.

If this is not the case, then you'll need to use the tool to change the
U-Boot environment from Linux.  For details see tools/env/README.  When
you have this working, simply adjust bootdelay again.
