Hi everyone,
I successfully run the echo example on my custom board based on i.MX 8M Mini.
imx_rpmsg_tty module works and I'm able to send some bytes from A53 to M4.
The example anyway should write back the same bytes via the rpmsg_lite_send_nocopy function from M4 to A53.
In fact I find these line with dmesg
[ 3.572174] rpmsg_tty_cb68 65 6c 6c 6f 20 77 6f 72 6c 64 21 hello world!
but if i run this command:
cat /dev/ttyRPMSG
the output is empty.
Of course i can run
echo blabla > /dev/ttyRPMSG
and just like before I find the answer from M4 with dmesg but the cat command gives an empty result.
What's the correct procedure to read the tty?
Thank you!
