Hi guys,

I am working to port the STM32 CUBE AUDIO library (made for STM32F4-F7 series) to the STM32H7 mcu, but I am experiencing lot of problem and the documentation is not useful to debug the problem, for 2 reason, no detail about the error code reported, and library provided as compiled, so no source code. In particulare, testing the SVC library while executing the code it report me the error "BAD_HARDWARE", is there someone more expert than me in STM32 that maybe has some good advice? If I at the end made it working I will provide and share the project made for test in order to be helpful to other who will made the same porting.

Thanks in advance

Problem solved, if someone need in the future this is what I have done to fix the problem:

Enable the CRC before calling any function of the library with this:

__HAL_RCC_CRC_CLK_ENABLE();
    CRC->CR = CRC_CR_RESET;

Then check the alignement of the buffers, otherwise the memcpy function will cause an hardfault.

Doing these now it is working
