Hello all,

We are trying to run Openamp project on petalinux 2017.4 on picozed board. 

As shown in the logs, demo application image_echo_test boots  and remoteproc0 also starts. 

But, as we give command of echo_test start, we are getting error message as "Failed to open rpmsg file /dev/rpmsg0."

the device tree settings for system-user.dtsi are done according to the settings UG1is mail. 186.
