FX3S SDIO | Cypress Semiconductor
I'm in the bring-up process for a PoC using the Pactron FX3S evaluation board.
Mass storage demo- works.
My SDIO project - doesn't.
Fx3SDIOUart - doesn't. (Hm...)
What happens is that it will see, ad infinitum, an SD card plugged into either port 0 or port 1 of the board. However, plug in an SDIO card (any, not just a serial- and for my application, any is what is required...), the device hangs HARD, needing to be unplugged and re-plugged in. Does this with either the SDK demo or my application I'm building up.
I debugged it to the event processing level above my callback- it's hanging before that. Do I have duff hardware here? What gives?
