Boot Linux OS from eMMC on Omap5432 EVM

Other Parts Discussed in Thread: PMP

Hi everybody

I'm booting Linux OS from eMMC on Omap5432 EVM.

When I boot from SD card. My OS can recognize SDcard partition is mmcblk0 and eMMC is mmcblk1.

So I modify u-boot and linux kernel source code by change 1 parameter of bootargs from "root=/dev/mmcblk0p2" to "root=/dev/mmcblk1p2".

Below is output log

Anybody tell me, my setting is wright or wrong ? Why my system still wait for root device /dev/mmcblk1p2

[ 12.493194] Waiting for root device /dev/mmcblk1p2...

Thanks

  • Hi Kenh,

    With what sysboot configuration are you running the board? Sometimes the switch doesn't  make good contact.

    Regards, Boyko

  • Hi Boyko

    I overcome this issue.

    This is reason :

    When I boot up from SDcard . EMV setting SD card is mmc0 and mmcblk0. eMMc is mmc1 and mmcblk1.

    So I think bootargs is set : root=/dev/mmcblk1p2 to boot up from eMMC

    But When I check the output log of eMMC boot, EVM setting eMMC is mmc1 and mmcblk0

    ---> Error :Waiting for root device /dev/mmcblk1p2...

    Fixed by : Set bootargs root=/dev/mmcblk0p2 

    Thanks
