  • I’ve been trying to get this board to work without much luck. SI toggles just fine but SO remains high and I always readback 0xff from any register.

    As a starting point, I just hooked up ground, 3v3 (on VIN), /SPI (to ground) and pulled SPI bus lines to my Aardvark SPI adapter and my Beagle I2C/SPI bus analyzer.

    The SC16IS750 doesn’t seem to be alive at all. I know it’s not the analyzer/bus-master because if I short SI/SO the analyzer sees the data just fine.

    Any hints ?

No public wish lists :(
