colibri_imx7: prepare environment to boot the M4 core
Create a variable to boot the Cortex-M4 core. By default, the command is not doing anything. Flash a firmware into the UBI volume using: Colibri iMX7 # ubi part ubi Colibri iMX7 # fatload ${interface} 0:1 ${loadaddr} hello_world.bin Colibri iMX7 # ubi write ${loadaddr} m4firmware ${filesize} And set the command to boot the firmware automatically: Colibri iMX7 # setenv m4boot 'ubi read 0x7F8000 m4firmware && bootaux 0x7F8000' Signed-off-by: Stefan Agner <stefan.agner@toradex.com> Acked-by: Max Krummenacher <max.krummenacher@toradex.com>
