Hi Diego, Peng,

The main reason for this update is due the currently README has no enough info to boot the board. Add a few more steps that make the board bootable.

As patch for mx8evk requires change, this is also postponed. Peng, I will suggest you put this (even as separate patch, I have nothing against it) in your next post.

Thanks, Stefano

This patch depends on Peng Fan's patch series: https://patchwork.ozlabs.org/cover/857942/

-Get and Build the ARM Trusted firmware

-Get ATF from: https://source.codeaurora.org/external/imx/imx-atf -$ make PLAT=imx8mq bl31

Build U-Boot

-Note: Better to use NXP released yocto to get the firmware in case

•  there is new releases.

Generate flash.bin using imx-mkimage

-Copy bl31.bin u-boot-nodtb.bin u-boot-spl.bin fsl-imx8mq-evk.dtb to

• imx-mkimage/iMX8M

• imx-mkimage/iMX8M
  

-If you want to run with HDMI, copy signed_hdmi_imx8m.bin to imx-mkimage/iMX8M +====================================

+Copy the following binaries to imx-mkimage/iMX8M folder:

+$ cp imx-atf/build/imx8mq/release/bl31.bin imx-mkimage/iMX8M/ +$ cp u-boot/u-boot-nodtb.bin imx-mkimage/iMX8M/ +$ cp u-boot/spl/u-boot-spl.bin imx-mkimage/iMX8M/ +$ cp u-boot/arch/arm/dts/fsl-imx8mq-evk.dtb imx-mkimage/iMX8M/

+If you want to run with HDMI, copy signed_hdmi_imx8m.bin to imx-mkimage/iMX8M.

+Before generating the flash.bin, transfer the mkimage generated by U-Boot to iMX8M folder:

+$ cp u-boot/tools/mkimage imx-mkimage/iMX8M/ +$ mv imx-mkimage/iMX8M/mkimage imx-mkimage/iMX8M/mkimage_uboot

+$ cd imx-mkimage/ +$ make SOC=iMX8M flash_spl_uboot

+Or for using HDMI:

+$ make SOC=iMX8M flash_hdmi_spl_uboot

+Flash the binary into the SD card +=================================

-make SOC=iMX8M flash_hdmi_spl_uboot or make SOC=iMX8M flash_spl_uboot to -generate flash.bin. +Burn the flash.bin binary to SD card offset 33KB:

-Burn the flash.bin to MicroSD card offset 33KB -$sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33 +$ sudo dd if=iMX8M/flash.bin of=/dev/sd[x] bs=1024 seek=33

Boot

+==== Set Boot switch SW801: 1100 and Bmode: 10 to boot from Micro SD.
