Hi Ashwinee,

             Could you please check if you are setting the "console" parameter in your boot arguments properly?

How does your bootargs look?

Regards,

Aditya

Hi Ashwinee,

Add "earlyprintk" to your bootargs as well as in kernel configuration, so that you can see the boot prints.

If above option is not enabled, we have to wait for some time to get the boot prompt provided bootargs are correct.

Look at this portion of the user guide to get more details on bootargs

Hi,

I am writing the script to make boot.scr. In the starting I just want to check that kernel is booting or not. So I am not adding rootfs related things.

The Boot.script is:

setenv bootargs 'console=ttyO2,115200n8 androidboot.console=ttyO2 mem=1G earlyprintk vram=32M noinitrd init=/init ip=off'
setenv bootcmd 'mmc init;fatload mmc 0 0x81000000 uImage;bootm 0x81000000'
boot

And I gave the below command to create boot.scr-

mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n 'Boot Script' -d Boot.script boot.scr

Thanks,

Ashwinee

Hi Ashwinee,

why are you passing "mem=1G" in bootargs? can you try with mem=256M

Make sure that earlyprintk is enabled in kernel configuration, so that you will get some prints.

Ashwinee,

  As pointed out in the earlier post you may have to set "console" parameter as appropriate. Can you please try setting console=ttyO2 and check if that helps.

Hi,

The boot arguments I have provided are:

setenv bootargs 'console=ttyO2,115200n8 androidboot.console=ttyO2 mem=512M earlyprintk vram=32M ip=off'
setenv bootcmd 'mmc init;fatload mmc 0 0x81000000 uImage;bootm 0x81000000'
boot

After that the log I am getting is:

Hi Ashwinee,

1. Provide the complete log after power-up, till the hang/crash (attach as separate file)

2. print all the environment variables, this can be get from u-boot prompt (attach as separate file)

# print

3. Make sure that earlyprintk is enabled in kernel configuration
