When a SPI transaction occurs, the HAL operates the SPI in "endless transaction" mode, which means that the SPI peripheral is not able to detect when a transaction completes.

The SPI_CR2.TSIZE register value needs to be updated with the size of the transaction in bytes before a transaction is initiated.

This behaviour seems to be OK for simple SPI usage, but fixing this would be an improvement 👍
