A long story, got an 8.0 IPO with a phone 16 expansion module. One port went dead on the module so it was changed out, but a V2 Module was installed. We've never been able to get it to work. So... as it was a V2 the IPO was upgraded to 9.0. It still doesn't work. (Other V2 modules have been tried) I'm guessing it's a bin file / firmware issue. My next step is to format and recreate the SD card to make sure all the correct bin files are there. Anyone got any other ideas?? And.. can I remove the SD card on a live system and will it stay running? I would power down before re-inserting the recreated SD Card.
