Waiting for root device on WaRP 7

[mohammedibrahim]

Hello NXP community,

I have recently purchased the WaRP 7 IoT development board that consist of an A7 and an M4 core. Im currently stuck with getting the board to boot fully as it seems to get stuck at message saying 'waitng for root device /mmc'..  We finally followed the instructions properly and managed to install the U-boot as per these instructions : WaRP7-User-Guide/U-boot.adoc at master · WaRP7/WaRP7-User-Guide · GitHub  and we also flashed a pre-built image (using the dd command ) which we downloaded off this link: http://freescale.github.io/#download. However when we rebooted the board we still get the issue of the board being stuck at the message mentioned earlier. Can someone please help as as even the experts in our team could not handle this problem with the linux set up on the board.

Can you try this image instead?

https://www.dropbox.com/s/hlslc7q3r2zsffl/sdcard.img?dl=0 

In U-Boot prompt:

=> ums 0 mmc 0

Then on the host PC:

sudo dd if=output/images/sdcard.img of=/dev/sdX; sync

I tried to DL the image from the link and it appears to have been deleted.  Do you have a newer one?

[fabio_estevam]

Hi Dan,

You can download a pre-built image for warp7 here:

http://freescale.github.io/#download

Thanks Fabio!

I have been trying to DL images from that link for a couple of weeks.  Kept getting 404 errors.  Thank you for updating them!

Should 1st update the U-boot before flashing this image of yours?

[fabio_estevam]

Just flash the entire image and it should update everything automatically.

[mohammedibrahim]

I see but before that i would llike to let you know that the boot sequence seemed to have worked by magic and now the board is asking for a username and password to log in but i dont know them. Apparently I was told that the there is some race condition which causes the board to boot properly and sometimes doesnt.

[fabio_estevam]

Please post the entire log from U-Boot to kernel.

How do i post my entire log from U-boot to kernel?

[igorpadykov]

Hi Mohammed

one can check if correct mmcblk number is used in kernel boot parameter,

please use Table 27. Linux uSDHC relationships attached Linux Guide

Best regards
igor

Hi,

so my the number I have is mmcblk2p2. so what should i do after this?

[fabio_estevam]

Since this U-Boot commit mmcblk2p2 is no longer used.

commit ca4f338e2efece5196eb2178e5f7d07be828da6e
Author: Fabio Estevam <fabio.estevam@nxp.com>
Date: Thu Aug 25 21:07:19 2016 -0300

warp7: Use PARTUUID to specify the rootfs location

warp7 can run different kernel versions, such as NXP 4.1 or mainline.

Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the eMMC
changes depending on the kernel version.

In order to avoid such issue, use UUID method to specify the rootfs
location.

Succesfully tested booting a NXP 4.1 and also a mainline kernel.

,so I suggest you to upgrade your bootloader.

[mohammedibrahim]

Right so how do i upgrade my bootloader (U-boot) ?

Here is the link I used to install the U-boot on the warp7, maybe you can tell me from which step do I use the commands you have in mind for upgrading the U-boot?

WaRP7-User-Guide/U-boot.adoc at master · WaRP7/WaRP7-User-Guide · GitHub 

[fabio_estevam]

You can follow these steps:

git.denx.de Git - u-boot.git/blob - board/warp7/README 

[danbrown]

I have followed those steps.  And the origional ones too...   When I flip SW2 up like in the directions, I get no serial console messages.  Happens on linux and windows clients.  I am unable to update u-boot due to this.   Any ideas?

[mohammedibrahim]

But those are the exact same steps in my link and we followed it earlier but still gave the same error in the boot sequence
