Can not burn Linux prebuilt image to iMX 8M Mini EVK with uuu

[im_tlau]

Hi NXP Community team,

I got an iMX 8M Mini EVK board, I was trying to burn Linux prebuilt images to MicroSD card, it always fails.

Images I tried are L4.14.78_1.0.0_ga_images_MX8MMEVK.zip and L4.14.98_2.0.0_ga_images_MX8MMEVK.zip.

Host Linux is Debian 10.0.

uuu is built from ttps://github.com/NXPmicro/mfgtools.git.

Switches on board set to SD Mode: 1010xxxxxx xxxxxxxxx0, 16G MicroSD card inserted.

Ran following command on Host Linux

uuu L4.14.78_1.0.0_ga_images_MX8MMEVK.zip
uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.3.34-8-g8bb3f01

Success 0 Failure 0

1:2 1/ 1 [=================100%=================] SDP: boot -f imx-boot-imx8mmevk-sd.bin-flash_evk

It hangs there forever.

Could you tell me anything I did wrong and what else I can try?

And the error messages on USB debug console (continuously if useing L4.14.98_2.0.0_ga_images_MX8MMEVK.zip):

I will test it on my board and give you detail steps.

[im_tlau]

One thing I missed, my board is i.MX 8M Mini DDR4 EVK.

Should be different with or without DDR4.

[Rita_Wang]

Yes, that's the problem. You are using the 8MMINID4-EVK board, the demo images are default for 8MMINILPD4-EVK. When you download the images you need to choose the uboot with the ddr4.  I do not have the board you are using, but I will do further confirming for you.

[im_tlau]

Hi Rita,

I guess you meant imx-boot-imx8mmddr4evk-sd.bin-flash_ddr4_evk in the L4.14.98_2.0.0_ga_images_MX8MMEVK.zip tarbal, I also notice the Image-fsl-imx8mm-ddr4-evk.dtb file, but there's only one fsl-image-validation-imx-imx8mmevk.sdcard file, and after flash this one to MicroSD card, it doesn't work with my DDR4 board.

The same reason uuu tool doesn't work since there's no parameter for DDR4, so it'll be great if you have any suggestions/steps to load prebuilt image on DDR4 board.

By the way, I've built the images by myself with following configurations:

repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m imx-4.14.78-1.0.0_ga.xml

DISTRO=fsl-imx-xwayland MACHINE=imx8mmddr4evk source fsl-setup-release.sh -b build

And I could flash the .sdcard image to MicsoSD card then running Linux on my DDR4 board successfully, didn't try uuu, but at least I can move forward now, but it'll be better if you can provide more information on DDR4 usage.

Thanks!

[Rita_Wang]

I do not get this board you are using, the only different is the DDR. So on software, only u-boot DDR configurations are different. When you are using the demo images you need to use with DDR4 as I told you above. And when you build BSP yourself, you need to confirm if the board.c file with ddr4 are exist. If yes you can build directly, if no, you need to configure the DDR first. I am try to get more information on this board. By now , no more materials found on our website. I get the update and will send to you as soon as possible.

Hi Rita and Hongbo, pleased to meet you,

I'm pretty sure I'm working on the same board as Hongbo does, since my logs look identical:

namely, it is the i.MX 8M Mini DDR4 EVK, where the bold word was added to mean "no LPDDR4", I guess.

I confirm that I managed to burn the 4.14.78-1.0.0_ga prebuilt images via UUU as soon as I replaced the u-boot file:

imx-boot-imx8mmevk-sd.bin-flash_evk

with:

imx-boot-imx8mmddr4evk-sd.bin-flash_ddr4_evk

now, since I have to move to a custom board and possibly make adaptations to u-boot code, can you confirm that I have to change the MACHINE variable from imx8mmevk to imx8mmddr4evk, and re-launch the yocto build?

Rita, can you please share any resource you may have found and shared to Hongbo? Thanks in advance.

More info, I ran following command to flash the image to SD card:

dd if=fsl-image-validation-imx-imx8mmevk.sdcard of=/dev/sdb bs=1M && sync

When booting it on the board, it hangs there with the following messages:

Do you have any idea about this?

Thanks again!

[im_tlau]

I reviewed other posts, is it possible that I use wrong USB Type A to USB Type C cable? I just used a normal one from the EVK connected to board's Port 1.

And I've built the images on my server with following configurations:

bitbake fsl-image-validation-imx

Could you let me know the steps to put the images I built to MicroSD card manually on Linux host?

Very appreciated for you help!

[im_tlau]

Thanks Rita!
