We can support up to a 32gig card. The debug files are extremely small. The panel will not format it, but most are in a format we are ok with (FAT32). That said, if you do not have a laptop or means to read the card it will be an issue sharing the files from the card.
If you were able to access the information on the card. After inserting the card, you would just enable SD Card and SD Card Debugging in System Settings. Than just operate the system for a few mins from the screen. Then remove the card and copy the debug file and send it to us. We can look it over from there. Note if you remove the card, it generates a SDCard trouble condition until it is disabled in System Settings.
But this would depend on a way to read the SD Card as I wouldn’t want to ask you to send us the whole card.
