  1. Oh BU***R !!! My bad !!!. I mistook your schematic which referred to SDI on the SDARD. I always get these pins confused - and now ALWAYS use the MISO/MOSI standard - so its not ambiguous :-(. Sorry - please disregard this previous posting :-O. BR Graham
  2. Hi, I have a couple of your Wi-Fire RevB modules - excellent boards so far !!. I have done very little with them yet - waiting for Microchips Harmony to 'settle' - its now usable - at V1.03.01 ;-). I have a basic config in and at least running - I can send data out of UART ports so far. So - I now started mapping the IO pins so that I can add my own chips on an add-on board, and the first problem I hit is trying to map your on-board SDCARD :-(. Your spec says that I can drive it with an SPI - which is what I want to do, BUT it also says that SDI3 needs to be connected to pin C4 (CPU pin 9). BUT - this is NOT a remappable pin for this CPU, which can be allocated to SPI3 :-(. I assume that you will fix this in a Rev C board soon ????. If so - what pin will you allocate - so that I can cut & strap my board accordingly - and also avoid using this pin for any other interface :-O. NB I am trying to create a manufacturable 'product' for a client using this module and an add-on board (for custom hardware extension). Many Thanks - hopefully ;-). Best Regards Graham
