KV58, SPI Master

Question asked by Christie Su on Nov 11, 2019


I am using SPI sample code "dspi_polling_b2b_transfer_master.c" for KV58.

I am using SPI0, PCS0 and PCS1 to control my SPI slave devices. I can't get the right value from slave device.

But, I control SPI0 and SPI1 by using GPIO, it works fine.


I checked that PCS0 and PCS1 are going to LOW/HIGH in both cases.

Can anyone tell me where I need to adjust to make it work in both cases?
