Hello,I am working with a STM32F446ZET6 and using it as an SPI slave.I use the function HAL_SPI_Transmit_Receive_IT function to receive 4 bytes of data.It used to work properly in our conception, for example when the master sends 0x12, 0x34, 0x56, 0x...

Hi To what does the revision code correspond?I have not found any clear answer in the documentation.Does a new revision replace the previous one? if so how to know which one is the most recent.

I ask the question as I have actually flash to binary on my stm32 via Keil, I have a loader and an application. Is there some tool to flash both in one instance?

Hello, I am using Keil and generating a *.bin file of my program from the *.axf file.I would like to know if there is a way to check before loading the binary file if it is corrupted.Is there some checksum to read or something.

Hello,I'm working with a STM32F446 and I configured the SPI as slave.In my process I receive x bytes of data in interruption. But during the process, this size of data changes to y. But the function HAL_SPI_TransmitReceive_IT(x) has already been call...

After more debugging, we have found that when using the function HAL_SPI_TransmitReceive_IT we sometimes miss a byte:As slave we are receiving 4 bytes every cycle (100us), between each byte the CS is toggled by the master.At the beginning the SPI com...

I understand what you are telling me and I'm trying to debug it.But I want to know if it means then that the behaviour of a code can be different depending on the chip (still in the STM32F446ZET6 series)? Does it mean that I will have to write anothe...

Yes, i understand that. But the thing is that at the beginning the devices are synchronized.If fact the behaviour is strange: like 80% of the time the reception will be ok (0x12, 0x34, 0x56, 0x78), but then during 2 receptions some data will be flipp...

But this only appens on 1 of my board, out of 10 having the same programm.I only read the content of the SPI buffer after the interruption of the function HAL_SPI_TxRxCpltCallback(). After reading the content of the buffer, I restart the same pattern...
