Linux: AM1808 issue while booting

Tool/software: Linux

Hi,

I have two AM1808 SOM modules. One boots up properly, with same kernel & ramdisk the other hangs after "Uncompressing Linux... done, booting the kernel." Please help me to debug this issue.

Thanks and Regards,

Hello Dileep,

At first you can compare the two U-Boot environments.

Best regards,

Hi,

I checked, on both boards U-boot environments are same.

U-Boot > pr
bootcmd=if mmc rescan 0; then if fatload mmc 0 0xc0600000 boot.scr; then source 0xc0600000; else fatload mmc 0 0xc0700000 uImage; bootm c0700000; fi; else sf probe 0; sf read 0xc0700000 0x80000 0x220000; bootm 0xc0700000; fi

Are these AM1808 SOM modules with identical hardware? Have you checked that if the kernel doesn't route the logs to another tty port?

Both SOM modules are identical. To cross check if it routes to other tty, i have tried all the options in Uboot environment.
