Hello,
I'm trying to launch OPENAMP tty echo demo project. I succeed one time, the tty was correctly created and i can communicate. But I recently flash the SD using dd tool and after this operation the M4 code stuck in MX_OPENAMP_Init on :
while(resource_table.vring1.da != VRING_RX_ADDRESS)
Maybe something wrong in the device tree but i don't find any solution on web or this forum (i tried the solutions offered in an other post on this forum, but no results).
Best regards,
Robin.

Hi @RMeys.1​
Can you please give some precision on the image you flash on SD ?
if you come back to Starter Package delivered by ST is it back working ?
Thanks
Olivier

Hi @RMeys.1​
Hanging in MX_OPENAMP_Init is typic of remaining Clock Init function while in production mode.
Take care to remove or put under IS_ENGINEERING_BOOT_MODE() condition, call to functions SystemClock_Config(); and PeriphCommonClock_Config();
cf this old post :
Hope it help,
Olivier
