Dear all, I'm experiencing a problem (especially when I am in debug). I use slave SPI with DMA  to transfer a 64bytes block and after a timeout i set the VLPS mode disabling first the SPI, aborting transfers and resetting it. When I go back in RUN mode, I reinitialize the SPI and DMA again but the SPI communications restarts with a problem, the whole buffer is shifted, from the K1xF (the slave) the first sent byte is the byte 8, then all other 56 bytes and at the of the frame I get what should be from byte 0  to 7.

Any idea?
