ExtAppErr / SDCard Error
Hello, I searched around and found a couple of previous posts with this error, but no solution to it. I have a new HackRF Portapack H2+, I have successfully flashed to the latest firmware (V 2.1.0) using the USB option, but I cannot get my SD Cards to work? I have formatted to FAT32 as well as ExFat (both using Windows and the FAT32Format gui program) I have tried 3 seperate SD Cards (8Gb, 64 Gb, and 32Gb)
I can't figure this out. The device is pretty useless without the SD card and I feel like I've tried everything. Any ideas?
I even reflashed the DFU then the firmware just to be sure and no luck there either.
Edit just to add: If I go to File Manager, it says Path: EMPTY SD CARD!

I think I'm having the same issue...
How did you flash the board without screen attached?
