IMX7ULPEVK - Waiting for root device /dev/mmcblk0p2...

[Raxesh-Oriya]

I have IMX7ULPEVK with me and checked out imx-5.4.70-2.3.0.xml manifest from zeus branch. Generated imx-image-core after syncing repo. Flashed generated image on uSD card. Inserted uSD card in slot and powered on the board. 

Kernel hangs up at Waiting for root device /dev/mmcblk0p2...

I have seen similar questions but couldn't get rid of this error.

Any leads?

Hello Everyone,

I'm just wondering if someone knows how to fix this issue. I'm having the same problem but I'm using eMMC instead of an SD Card.

Hello Everyone,

I'm just wondering if someone knows how to fix this problem. I'm facing with the same issue but I'm using eMMC instead of an SD card.

[laugechristense]

Is there any news on this issue?

I appear to be have the exact problem.

I am using a MCIMX7ULP-EVK REV B1 with no modifications.

After building the newest (5.10.72) images I ran into problems. To rule out problems in the build-process, I tried downloading the images build by NXP from

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applicat...

I transfer the prebuild *.wic images (e.g. imx-image-full-imx7ulpevk.wic ) to the microSD card that came with evaluation kit. I tried two different microSD cards.

For linux version 5.4.3 it works and the board boots as expected. it also works for the earlier versions, that I tested.

For linux version 5.4.24, it hangs at:

[ 3.478015] Waiting for root device /dev/mmcblk0p2...

sometimes followed by

This also happens for the later versions that I have tried.

Is there anything in the process that is supposed to be different for the later releases?

Kind regards,

Lauge

[Rita_Wang]

How about the SD speed you are using? And have you tried the demo images in our website, does it work?

[Raxesh-Oriya]

How do I check SD speed?

Edit: I get mmc0: new ultra high speed DDR50 SDHC card at address aaaa from log. is this what you are referring to?

I tried following demo image:

Looks like an issue with 5.x kernel..

[Rita_Wang]

I have tested on my board with the SD card, it work well with the LF5.10.35_2.0.0.

I think the error in your side caused by the SD card you are using. If you have others card in your side you can try it.

Hi,

  Are you using the M4 image provided with the release?

  I tried it on 5.10.72 with an old M4 image. Then I can reproduce the issue.

  Then I replace the M4 image with the image provided by 5.10.72 release.

  Update script:

setenv m4_copyaddr 0x62000000
setenv m4_flash_image imx7ulp_m4_demo.img
setenv m4_flash_imglen 0x40000
setenv m4_flash_imgaddr 0x0
setenv m4_loadimage "sf probe;sf erase '${m4_flash_imgaddr}' '${m4_flash_imglen}';fatload mmc '${mmcdev}':'${mmcpart}' '${m4_copyaddr}' '${m4_flash_image}';sf write '${m4_copyaddr}' '${m4_flash_imgaddr}' '${m4_flash_imglen}'"

  Run command "run m4_loadimage" in u-boot and when the M4 image has been flashed to spi-flash. Power cycle the board.

 Now you should be able to enter kernel.

  Thanks!

Regards

Terry

Late reply, but this still works!

Thanks man! Saved a lot of work here.

Thanks Terry! This worked for us over here.

I had downloaded the pre-built image L5.15.32_2.0.0_MX7ULP1 (LF_v5.15.32-2.0.0_images_IMX7ULPEVK.zip) from the NXP website. And prepared microSD card using the command (as per the reference manual),

dd if=imx-image-full-imx7ulpevk.wic of=/dev/sdb bs=1M && sync

However, on trying it out on the EVK we encountered the same hang like state as originally reported by @Raxesh-Oriya .

I checked the boot switch and it was already configured for "dual boot". So that wasn't it. Then I tried @terry_lv 's U-Boot script (for running m4_loadimage). Immediately after that step, doing a warm-boot of the EVK via U-Boot (reset command) the problem was still there. But then I turned the EVK off and then on again (cold boot). This time the problem went away.

I just wanted to share our experience as a confirmation of the proposed solution.

Just for reminder.

Please modify the boot mode to "dual boot", if the sf command has benn successfully operated, then the M core will be on then Linux boot.

Also thanks for the help from@terry_lv.

I will test on my board next week and confirmed for you and then give you feedback.

Hi @Rita_Wang 

Did you get a chance to test on your board?
