HI Henner, I've noticed this to while doing the overlays: SPI1 CS1 is used as CS https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/PB-SPI1-ETH-CLICK.dts#L83 SPI0 CS0 is used as CS https://github.com/beagleboard/bb.org-overlays/blob/master/src/arm/PB-SPI0-ETH-CLICK.dts#L83 I haven't looked to closely, (just let my automated script setup the pinmux's).. But if SPI1 (CS0) and SPI0 (CS1) is not on the header, we should remove them from the base tree: Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
