Flashing i.MX8MPEVK demo image using UUU not working

[deepika_t]

Hi All,

I downloaded demo images L4.14.78_1.0.0_ga_images_MX8MMEVK.zip

SW4 settings are

switch D1  D2    D3   D4
SW4 OFF OFF OFF ON

Attaching the screenshot for the same:

Hi Igor,

I was going through https://github.com/NXPmicro/mfgtools/issues/183 and came across the term ROM patch

When I flashed the demo image using the uuu tool and loaded u-boot. I gave the following command.

u-boot=> fuse read 0 0
Reading bank 0:

Word 0x00000000: ffafa9eb
u-boot=>

Is there any issue in the board?

Thanks,

Deepika

HI All,

In the prebuilt binaries there was a uuu.auto.

I tried with uuu.auto and copied the rootfs.wic inside the uuu and added the name of the rootfs file in the uuu.auto.

With this I was able to flash full image

This is for anyone who is stuck.

Thanks,

Deepika

Hi Igor,

Thanks for the reply.

The demo image which was shared has been flashed successfully.

I have also built Yocto Image for  i.MX8M Plus EVK using the Yocto project user guide and I followed the following steps. The build was successful

repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-hardknott -m imx-5.10.35-2.0.0.xml
$ repo sync

Gave the following command after repo sync
DISTRO=fsl-imx-wayland MACHINE=imx8mpevk source imx-setup-release.sh -b build

With the images inside build/tmp/deploy/images , I tried using uuu for flashing the Yocto built images.

But getting error.

I need to flash the entire multimedia image using the uuu tool.

Is there any document for the same?

Thanks,

Deepika

Hi Deepika

recommended to try latest Linux 5.10.9_1.0.0 images as L4.14.78 is outdated release

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

Also what board used in the case, as " i.MX8MPEVK demo image" should be used for i.MX8M Plus EVK

and "L4.14.78_1.0.0_ga_images_MX8MMEVK.zip" with i.MX8M Mini EVK.

Best regards
igor
