OPENAMP tty demo M4 stuck on MX_OPENAMP_Init

[RMeys.1]

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

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,
