Value error firinit()

Just received my pure thermal board. I have a problem getting the Lepton 3 to initialize. The sensor is good, tested it in an H7 R1. When I load the script example thermal_overlay_lcd_1.py The camera displays a brief picture then I get a firinit() line 18 "value error failed to detect a supported FIR sensor. I have other lepton sensors available, same results.

I don’t have a working OpenMV-Pure Thermal to test with, maybe @kwagyeman can give it try. In the mean time, the best I can say is to try the development firmware.

Thanks, Kwabena is helping me. The IDE helped identify the problem, not much to do in S/W.
