i.mx6ull evk fails to boot with factory provided sdcard.

[HEgan]

I'm assuming the sdcard simply needs a new image.

I can't find where the pre-built evk image is on NXP downloads area.

Can somebody provide a link to the correct image?

FWIW here is the uart output.

Thanks Aldo:

I'm not seeing pre-compiled images for i.mx6ULL in the link above.   What would the filename be called?

I downloaded this file LF_v5.10_2.0.0_images_IMX6UL7D.zip from this link.  
https://www.nxp.com/webapp/Download?colCode=L5.10.9_1.0.0_MX6UL7D&appType=license

There are 2 wic images
imx-image-full-imx6ul7d.wic and
imx-image-multimedia-imx6ul7d.wic

That doesn't look like what I want is it?

Also for certain the micro SD card is in the socket.

Hi,

Yes it is the correct file, please note that the image have support for other processors as well, like the i.MX6UL EVK or the i.MX7D sabresd, you may use any of the 2 you have mentioned for the i.MX6ULL EVK.

BR,
Aldo.

OK I'm wondering if there is something wrong with my EVK.

Flashed this onto the micro SD card
imx-image-full-imx6ul7d.wic

And I get this endlessly:

Hello,

I believe that you're copying the image to your uSD card using the following command, correct?
sudo dd if=imx-image-full-imx6ul7d.wic of=/dev/sdx bs=1M && sync

Please try with the same uSD card to overwrite the uboot file with the following command:
sudo dd if=u-boot-imx6ull14x14evk_sd.imx of=/dev/sdx bs=1k seek=1 conv=fsync

BR,
Aldo.

Odd, so it seems that the pre-built images do not work.

I did do a full bitbake build of imx-image-core, and flashed imx-image-core-imx6ull14x14evk-20210827231719.rootfs.wic.bz2 using ballenaEtcher and everything finally booted.

Not really sure what to make of that.

[HEgan]

Darn still same result.  Using those two commands in sequence.

Tried a couple other uSD cards too.

[HEgan]

Oh cool thanks.

Hello,

Please make sure that the MicroSD card is inserted into socket J301 on the CPU board (700-28617)

For downloading pre-compiled images, you'll find them here:
