According to the reference manual the shp_2_mcu / mcu_2_shp scripts must be used for devices connected through the SPBA. This fixes an issue we saw with DMA transfers from SPI NOR Flashes. Sometimes the SPI controller RX FIFO was not empty after a DMA transfer and the driver got stuck in the next PIO transfer when it read one word more than expected.
