How to loading Code on Cortex-M4 from Linux/u-boot for the iMX8MQ

[trongthinh]

There are some demo binaries for imx8mq-evk. I found them in output folder after building source. I am using meta-fsl-bsp-release (4.9.88-2.0.0)

IMAGE_BOOTFILES += "imx8mq_m4_TCM_hello_world.bin imx8mq_m4_TCM_rpmsg_lite_pingpong_rtos_linux_remote.bin imx8mq_m4_TCM_rpmsg_lite_str_echo_rtos.bin"

My question is "Is there any document or user guide that help me flashing these firmware to M4 core?" I don't know how to use these firmware. Many thanks for help!

Hi Igor,

I follow your instruction. It takes me to download "iar_segger_support_patch_imx8". Though It is useful, I am looking for another way. Eg.  use u-boot to start M4 core (correct me if i am wrong).
