imx8qxp mek evaluation board uuu bootloader failed.

Hi guys,

I have a trouble thing about uuu flasing to emmc in imx8qxpmek evaluation board.

I have connected USB C type to imx8qxpmek and tried to flash images included in bootloader image.

my sequence is like below:

sudo uuu/uuu ./uuu.auto

and result is that :

1/1 [HID(W):LIBUSB_ERROR_IO ] SDPS: boot -f imx-boot-imx8qxpmetk-sd.bin-flash.

I am suspecting wrong bootloader image but, i have tried other bootlaoder imag such as (imx-boot-imx8qxpmek-sd , imx-boot-imx8qxpmek-sd.bin-flash_linux_m4, imx-boot-imx8qxpmek-sd.bin-flash_lregression_inux_m4), but all failed.

Do you have any idea to fix my issue?

Thanks,

Hi guys,

I have a Imx8qxpmek rev C and I am using kernel 4.14.98.2.0.0, but it is always failed.

So, I have changed to imx8qxpmek 4.14.98_2.3.0 images and then download it and it is ok.

I have a question for it. Should I compile it for imx8qxpc0 ? if so, how do i compile it in yocto?

Do i use kernel 4.14.98.2.0.0 images for imx8qxpmek rev C?

kernel 4.14.98.2.0.0 does not support i.MX 8QuadXPlus (C0) MEK as described on below

Hi guys,

Thank you for answering.

I have additional question. How should I build imx8qxpc0 yocto build in kernel 4.14.98_2.3.0?

it is the same as for kernel 4.14.98_2.0.0, for rev.C0 one needs to build SCFW with "R="

silicon revision option, described in SCFW Porting Kit

Hi guys,

I want to know how to build imx8qxpc0mek in yocto.

Do I just change MACHINE=imx8qxpc0mek or other thing is changed?

Could you please confirm below commands?

=================

$ mkdir imx-yocto-bsp
$ cd imx-yocto-bsp
$ repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-sumo -m
imx-4.14.98-2.3.0.xml
$ repo sync
$ DISTRO=fsl-imx-xwayland MACHINE=imx8qxpc0mek source fsl-setup-release.sh -b build-xwayland
$ bitbake fsl-image-qt5-validation-imx

====================

yes MACHINE=imx8qxpc0mek is sufficient.
