m4fwloader issues

suryapradhan — Tue, 09 Jan 2018 11:21:03 GMT

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

i.MX Software|NXP

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
