remotoproc driver

[utopia61]

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

HI!

THe question now is imx-rproc driver can not load? How do I modify device tree and imx-rproc driver?

Thanks!

&rpmsg{
  status = "disabled";
};
