Hello
I am working with IMX7D based board & using "m4fwloader" tool to load,start & stop the firmware to Cortex-M4 from linux- cortex A7.
But i got one issue here, while stopping the firmware & starting again.
Scenario:
I am using "rpmsg_str_echo_freertos_example.bin" firmware & able to communicate with M4 properly.
Next i stopped it & started it again using "m4fwloader stop" & "m4fwloader start" command.
Now if i do "echo hi > /dev/ttyRPMSG", i am getting all my previous messages[message from last communication] along with new message.
Any suggestion on this.
Regards
Surya
Hi Surya
what bsp used in the case, had you tried with official nxp releases described on
using nxp i.MX7 Sabre SD reference board.
Seems it can be debugged using sources info given in
New i.MX6SX & i.MX7D AMP debugging tool: imx-m4fwloader
Best regards
igor
