Can't flash image via uuu on NXP Official IMX8MP EVK

13614278 — Tue, 25 Jul 2023 05:33:19 GMT

We have an offical NXP IMX8MP EVK board(8MPLUS-BB), it works fine for a few weeks, I mean, we can flash the image and the board can up without any issue.

But today I found I can't flash it anymore, when I put it under download, and using below command:

uuu -b emmc_all imx-boot-imx8mpevk-sd.bin-flash_evk imx-image-full-imx8mpevk.wic

It always failed to flash, and the board was in uboot shell prompt:

BuildInfo:

All the image files are the official file downloaded from NXP official website, not our own build. The full serial port output log is attached here.

Could someone give us some help? Thanks

Hi,

Thank you for your interest in NXP Semiconductor products,

What BSP release are you using? Could you try with another one?

Have you tried with an SD? What were the results?

Try also with:

uuu -b emmc_all imx-image-full-imx8mpevk.wic

Regards

Thank you for help.

We used the Kirkstone(5.15.71 kernel) for a while without any issue. Unfortunately, we found it failed to flash by uuu anymore recently.

Then, I tried other version such as gather(5.10.72 kernel) release, the same behavior, still can't flash the image by uuu.

I dumped the image into a removable SD card, and insert it into the board, and choose boot from SD mode, it can work.

Does that mean, the emmc was broken on the EVK board? because I find 'card not present' in the boot log(the log file already attached in this thread).

Please note that all the images I flashed was downloaded directly from official NXP website, to make sure the issue was not caused by our build environment.

Hi,
It's possible. Discard it updating uuu to its most recent version and also try the uuu.auto version withouth an SD plugged.

We spend some time on this, and found this is probably caused by following error report (-62):

tcpc_pd_receive_message: Polling ALERT register, TCPC_ALERT_RX_STATUS bit failed, ret = -62

...

## Checking Image at 43800000 ...
Unknown image format!
Run fastboot ...
USB init failed: -62

Could someone give us some advice?

After debugging, we found the failure code -62, is -ETIME

tcpc_pd_receive_message: Polling ALERT register, TCPC_ALERT_RX_STATUS bit failed, ret = -62

...

## Checking Image at 43800000 ...
Unknown image format!
Run fastboot ...
USB init failed: -62

The overal call sequence is:

tcpc_pd_receive_message() --> tcpc_polling_reg()

As we doing this uuu flash on the official NXP IMX8MP EVK board(8MPLUS-BB), with the official image files downloaded from official NXP website. Can we conclude there is something incorrect on this EVK hardware board ?

Hi,

Please try to recover it from linux as:

4.4.2 Using an i.MX board as the host server to create a rootfs.

Suggests.

Do you see it in linux?
