we need to have a commucation between the development board and Am335x via MsSPI , And the AM335x use as Slave mode. But after the test AM335x McSpi only works in Master mode. I do not know how the SPI Slave mode should be configured, how to change the software driver .if you has a SPI driver as a slave-mode or related routines. wish you could email to me .Looking forward to replying to me, thank you!
