Hi experts,
I got it, thank you.
BTW, I got an issue that using SPI 30M Hz in master mode works for our application, but it doesn't work on 40M Hz, the way of configuration is the same as you mentioned.
The issue is that the data the Host received is wrong.
I will look up the signals of CLK, MOSI and MISO on the oscilloscope first, then report to you on the other thread if the issue is still there.
Thanks again.
Best Regards,
TonySH
