STM32H563ZI - IT based HASH HMAC calculation leads to ErrorCallback

[ser]

HW: NUCLEO-H563ZI

Hello, can someone explain the following behavior to me? Is this a bug or am I using the HAL incorrectly?

Thanks a lot.

Code snippet

The result

The result is correct, but the behavior is strange. I receive two error callbacks also.

• First IRQ
• Second IRQ 
  • HAL_HASH_InCpltCallback
• Third IRQ
• Fourth IRQ
  • HAL_HASH_DgstCpltCallback
  • HAL_HASH_ErrorCallback
  • HAL_HASH_ErrorCallback

My analysis

First HAL_HASH_ErrorCallback due to:

1. state = READY
2. calling WriteData_IT

READY state leads to ErrorCallback

Second HAL_HASH_ErrorCallback due to:

1. With __HAL_HASH_ENABLE_IT starts the process described above (four IRQ’s)
2. Then, calling WriteData_IT and the READY state leads to ErrorCallback again

Hello @ser ,

I'm trying to reproduce the issue you are facing .it would be great if you can share the tool versions and Firmware version you are using also i would recommend you try to see the example given in the cubeFrimware and see if you can see any araised errors from the error callbacks .
it would be great as well if you can recover the call stack which lead to the error callback in your case by setting a breakpoint just before you increment the counter.

Hello @ser ,

I confirm this issue, the HAL function is not supposed to arise errors when the configuration and call to the function and the result is calculated correctly.

this has been reported internally.
