Hello, I am working on integrating IC880A to my jetson nano dev kit version, but i am having a problem with spi port. I cannot communicate with IC880A, i did several test and i followed several related topics to the same problem but the same thing. i tried to change the pinmux configuration using…

The problem is solved, the issue is CS pin was configured as active-high while the module work with active-low cs pin and i did referenced to this topic to change cs pin configuration Link
