8MMINILPD4-EVK Hangs with clean Kernel

Hi, 

 

I'm trying to build my own kernel to use with 8MMINILPD4-EVK, but the board doesn't boot.

 

Steps I'm using:

Set the board to download mode and flash  L4.14.98_2.0.0_ga_images_MX8MMEVK.zip

sudo ./uuu L4.14.98_2.0.0_ga_images_MX8MMEVK.zip

 

Build Kernel:

$ git clone https://source.codeaurora.org/external/imx/linux-imx
$ cd linux-imx
$ git checkout origin/imx_4.14.98_2.3.0 -b imx_4.14.98_2.3.0

$ export ARCH=arm64
export CROSS_COMPILE=aarch64-linux-gnu-
export PATH=/media/workspace/.bin/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu/bin/:$PATH
make defconfig
make -j25 Image dtbs modules
make modules_install INSTALL_MOD_PATH=./modules

rm -rf ./modules/lib/modules/4.14.98-06659-g0347fe7527d06-dirty/build
rm -rf ./modules/lib/modules/4.14.98-06659-g0347fe7527d06-dirty/source

scp arch/arm64/boot/Image root@192.168.86.250:/run/media/mmcblk2p1/
scp arch/arm64/boot/dts/freescale/fsl-imx8mm-evk.dtb root@192.168.86.250:/run/media/mmcblk2p1/
scp -r ./modules/lib/modules/4.14.98-06659-g0347fe7527d06-dirty root@192.168.86.250:/lib/modules/

 

It a clean kernel, no changes made.
