Hi nagaprasad
one can try procedures described in sect.2.6 Remote Processor Messaging, sect.9.19
Remote Processor Messaging attached Linux Manual
rpmsg\test - imx-test - i.MX Driver Test Application Software

Hi igor,
Thanks for your reply, i have seen link you provided.but for that it is required that there should be a node in /dev i.e,
"/dev/ttyRPMSG". i am not able to get this when i loaded modules in imx7dsabresd.
Thanks & Regards,
Prasad.
Hi Prasad
could you try with Demo Images from
for example Linux Binary Demo Files - i.MX 6UltraLite, i.MX 6ULL, i.MX 7Dual
