If the device tree dedicated to be used with Cortex-M7 applications is not being currently used, the script will give instructions on how to do so: | |||
Error: /sys/class/remoteproc/remoteproc0 not found. | |||
Please enable remoteproc driver. | |||
Most likely you need to use the correct device tree, for example: | |||
fw_setenv fdt_file imx8mp-var-dart-dt8mcustomboard-m7.dtb && reboot | |||
