Remoteproc driver

Hello all!

I’m suing IMX8MPlus, the linux kernel is 5.4, now i wan to use the remoteproc driver to boot M7 from linux,What should I do?

I tried to modify the device tree, but encountered some problems:

root@verdin-imx8mp-06965600:~# dmesg | grep rproc
[ 1.682743] remoteproc remoteproc0: releasing imx-rproc
[ 2.458897] remoteproc remoteproc0: releasing imx-rproc
[ 2.464181] imx-rproc: probe of imx8mp-cm7 failed with error -16

Best regards!

Verdin iMX8M Plus Quad 4GB V1.0
Verdin Development Board V1.1B
Linux BSP 5.4-2.3

Hi @utopia , current supported remote processor messaging on iMX8MP is RPMSG. Hi @gustavo.tx , do you have any information about remoteproc support plan? Thanks!

Hi, @gustavo.tx
What is current status of remoteproc support? I need upload firmware to M7 from running Linux OS and start/stop M7 CPU.
