stm32h757IITx - open amp project not works | simple shared data M4-M7 github project not works

[sqwerize]

My project:https://easyupload.io/m/aqdlx7

Hello, I created a proprietary board with stm32H757IITx. Unfortunately, I have problems with data transfer between M4 and M7.... I am using SRAM4, configured MPU and used github project:
GitHub - adailtonjn68/STM32H7xx_inter-core_data_share

Unfortunately, but I have a problem all the time in the M7 to upload the data that the M4 is supposed to receive.... When I debug the M4 it works without a problem and the data is placed correctly.

The problem always arises here, the code falls into hard fault:

int put_to_m4(const int *const restrict buffer, const unsigned int size)
{
/* Try and get lock */
if (atomic_flag_test_and_set(&shared_data.lock1)) <----- here i have HARD_FAULT
{
  /* Return -1 in case lock is not acquired (used by other core)*/
  return -1;
}

I tried a clean project with open AMP but it also does not work, I have status = -2005 in M4 in this line:

/* Create an endpoint for rmpsg communication */.
status = OPENAMP_create_endpoint(&rp_endpoint, RPMSG_SERVICE_NAME, RPMSG_ADDR_ANY, rpmsg_recv_callback, NULL);

Hello @sqwerize ,

1- Please in next time use </> button to paste the code. See this link. I've updated your post.

2- OpenAmp belongs to the "STM32 MCUs Embedded software" forum board not to "STM32 products" forum. I moved it to the correct one. 

Thank you.
