IMX8QM-EVK boot fail

Hi all，

I am working on burning image to emmc on iMX8MQ-EVK.

Now, I got an error：kernel in emmc is not be boot by bootloader. log as follow:

Could you tell us which board are you using iMX8MQ-EVK or iMX8QM-EVK? They are different. Could you tell us which version BSP are you using, and you download the demo images or images you build yourself?

Re: IMX8QM-EVK boot fail

zhengbing — Wed, 11 Nov 2020 10:31:38 GMT

Thank you for your reply，

Sorry for error description, I am using iMX8MQ-EVK.

BSP: L5.4.47-2.2.0

I refer to 《i.MX_Linux_Users_Guide.pdf》《i.MX_Yocto_Project_User's_Guide.pdf》, and Image is built by myself.

Look forward to your reply. Thank you again.

Re: IMX8QM-EVK boot fail

Rita_Wang — Thu, 12 Nov 2020 08:48:10 GMT

In your build, which command are you using? When you download does it success? Or can you give your details steps, to see if some unreasonable operation.

Re: IMX8QM-EVK boot fail

zhengbing — Thu, 12 Nov 2020 11:06:24 GMT

Thank you for your reply.

1、yocto and sdk:
Refer to 《i.MX_Yocto_Project_User's_Guide》 and 《i.MX_Linux_Users_Guide》.
bitbake imx-image-full -c populate_sdk.

finally, I got yocto enviroment and sdk enviroment.

2、build kernel:
git clone ....; git checkout origin/imx_5.4.47_2.2.0;
source /opt/fsl-imx-wayland/5.4-zeus/environment-setup-aarch64-poky-linux;
make imx_v8_defconfig && make;
so, I got 'linux-imx/arch/arm64/boot/Image' and 'linux-imx/arch/arm64/boot/dts/freescale/imx8mq-evk.dtb';

3、build uboot:
git clone ....; git checkout origin/imx_v2020.04_5.4.47_2.2.0;
source /opt/fsl-imx-wayland/5.4-zeus/environment-setup-aarch64-poky-linux;
make distclean && make imx8mq_evk_defconfig && make.
so, I got 'uboot-imx/u-boot-nodtb.bin', 'uboot-imx/spl/u-boot-spl.bin', 'uboot-imx/tools/mkimage' and 'uboot-imx/arch/arm/dts/imx8mq-evk.dtb';

4、build atf:
git clone ....; git checkout origin/imx_5.4.47_2.2.0;
source /opt/fsl-imx-wayland/5.4-zeus/environment-setup-aarch64-poky-linux;
make PLAT=imx8mq;
so, I got 'imx-atf/build/imx8mq/release/bl31.bin';

5、build fash.bin by using mkimage:
git clone ....; git checkout origin/imx_5.4.47_2.2.0;
copy imx-atf/build/imx8mq/release/bl31.bin to imx-mkimage/iMX8M/bl31.bin
copy uboot-imx/arch/arm/dts/imx8mq-evk.dtb to imx-mkimage/iMX8M/imx8mq-evk.dtb
copy uboot-imx/u-boot-nodtb.bin to imx-mkimage/iMX8M/u-boot-nodtb.bin
copy uboot-imx/spl/u-boot-spl.bin to imx-mkimage/iMX8M/u-boot-spl.bin
copy uboot-imx/tools/mkimage to imx-mkimage/iMX8M/mkimage_uboot
copy imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/lpddr4_pmu_train_1d_dmem.bin to imx-mkimage/iMX8M/lpddr4_pmu_train_1d_dmem.bin
copy imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/lpddr4_pmu_train_1d_imem.bin to imx-mkimage/iMX8M/lpddr4_pmu_train_1d_imem.bin
copy imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/lpddr4_pmu_train_2d_dmem.bin to imx-mkimage/iMX8M/lpddr4_pmu_train_2d_dmem.bin
copy imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/lpddr4_pmu_train_2d_imem.bin to imx-mkimage/iMX8M/lpddr4_pmu_train_2d_imem.bin
copy imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/signed_hdmi_imx8m.bin to imx-mkimage/iMX8M/signed_hdmi_imx8m.bin
make SOC=iMX8M flash_evk
so, I got 'imx-mkimage/iMX8M/flash.bin'

6、use uuu burn image on win10
copy and rename linux-imx/arch/arm64/boot/Image to _Image
copy and rename linux-imx/arch/arm64/boot/dts/freescale/imx8mq-evk.dtb to _board.dtb
copy and rename imx-yocto-bsp/build-wayland/tmp/deploy/images/imx8mqevk/imx-image-full-imx8mqevk-20201021065034.rootfs.tar.bz2 to _rootfs.tar.bz2
copy and rename imx-mkimage/iMX8M/flash.bin to _flash.bin
copy and rename L5.4.47-2.2.0_images_MX8MQEVK/fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot to _initramfs.cpio.gz.uboot

hi,

I tried to use command "uuu -b emmc_all flash.bin roofs.wic". It's working.

How can I get roofs.wic by Image&&dtb&&rootfs.tar.bz2 ?

Is there some kind of method that creating rootfs.wic ?

Best regards.

When you finished building, you can see the imx-image-full-imx8mqevk.wic or imx-image-multimedia-imx8mqevk.wic in your images directory. You do not need to do special operations.

Re: IMX8QM-EVK boot fail

Rita_Wang — Fri, 13 Nov 2020 09:18:30 GMT

I have saw your details, your steps are OK no errors found. The fail boot caused by the unreasonable set in kernel command line. As you renamed the download images name, so when uboot boot up you need also to unify the name in kernel boot up. When your uboot boot up, print and modify. It will also work OK. You can try.
