Hi,
SDK:PRU-ICSS-ETHERCAT-SLAVE 01-00-07-02
EVM:AM335X ICE V2
The customer refer to code located in am3359-pru-ethercat-slave\examples\board\iceAM335x and configured mcspi as master. He wants to realize communication between mcspi and multiple slave nodes( four or more). But the values of chNum in mcspi.h are from 0 to 3, does that mean I have to choose gpio as spi chip select and my question is what’s the chNum? How should I correspond chNum to the chip select? Please help explain the relevance between chNum snd spi chip select.
