I'm attempting to set up a SC589-EZKIT as a SPI device using a EI3 extender connected to P1B & P1C.
For some reason I cannot see the GPIO any pins on the EI3 extender changing from the ARM or SHARC0 cores, but observe proper SPI signaling with a digital scope on the extender.
Is there something that must be done to enable/configure the extender card?
Clarification of observations
