Hello

When I compile the kernel, How to set the machine name for 8MMINID4-EVK?

I use below for BSP.

 - repo init -u https://source.codeaurora.org/external/imx/imx-manifest -b imx-linux-rocko -m imx-4.9.88-2.0.0_ga.xml

thanks

After I set MACHINE to imx8mmddr4evk,  

===

$DISTRO=fsl-imx-wayland MACHINE=imx8mmddr4evk source imx-setup-release.sh -b build-core

$bitbake core-image-base

$DISTRO=fsl-imx-wayland MACHINE=imx8mmddr4evk source imx-setup-release.sh -b build-image-core

$bitbake imx-image-core

===

Each above two case, build error happened as below.

===

ERROR: core-image-base-1.0-r0 do_image_wic: Execution of '/nvme1/bryan/iot/imx8m-mini/imx-yocto-bsp/build-core/tmp/work/imx8mmddr4evk-poky-linux/core-image-base/1.0-r0/temp/run.do_image_wic.28387' failed with exit code 1:

BUT If I set MACHINE to imx8mmevk, build error did not happended. BTW why did not generated sdcard image file ?

Hi

With emmc ,Bootloader is “imx-boot-imx8mmevk-sd.bin-flash_evk”.Rootfs and kernel is “imx-image-full-imx8mmevk-20200708060549.rootfs.bz2 ”

Open shell/terminal：

       uuu -b emmc_all bootloader_name rootfs_name            ----------------------EMMC

       uuu -b sd_all bootloader_name rootfs_name            ----------------------SD

update all images: uuu -b emmc_all imx-boot-imx8mmevk-sd.bin-flash_evk imx-image-full-imx8mmevk-20200708060549.rootfs.bz2

update bootloader: uuu -b emmc bootloader_name

More details can see uuu.pdf.
