AM3358: Kernel boot stops

Hi All,


I am trying to upgrade my Current u-boot(2013) and Kernel (3.14) to latest u-boot(2017) and kernel(4.9) on beagleboneblack.

I am successfully able to boot latest image using SD card but after writing images into eMMC, it stuck at kernel saying  "Waiting for root device /dev/mmcblk0p2..".

As per my understanding when SD card is mounted on BBB then it show SD card as /dev/mmcblk0* and eMMC as /dev/mmcblk1*.

and  with only eMMC it  should be as /dev/mmcblk0*.

In my Latest kernel (4.9) log it states that "mmcblk1: mmc1:0001 S10004 3.56 GiB" without sd card for eMMC.i.e. eMMC is mounted on mmcblk1.

and thats why the error "Waiting for root device /dev/mmcblk0p2.." comes. Also when i change bootargs to /dev/mmcblk1p2 then it works.

but as per my older kernel log (3.14) without SD card, eMMC mount as "mmcblk0: mmc1:0001 S10004 3.56 GiB" means it takes eMMC as mmcblk0 and without changing bootargs it boots successfully from eMMC.

Kindly help where to start debugging for this issue. I dont want different Bootargs for eMMC and SD card.

I have attached Kernel_log.txt and Bootargs.txt for reference.

Regards,

Viraj
