Hi there, here is a short update. I am still waiting for that the production company works on the 4 PCBs in a panel according to my ideas. So there is no news from that experiment.
But I think I have found why there seems to be a problem with IrDA and why WLAN/Bluetooth are not working. The reason is that I can see under the microscope that the DM3730 is warped a little. There is one corner which shows more distance above the PCB than the other corners. And interestingly all control gpios for IrDA, WLAN and Bluetooth are sitting in this corner. That fully explains why I can't use gpio mode to enable WLAN or disable IrDA... So it looks as if this IrDA/WLAN issue is not a different problem but just a different symptom. I will try tomorrow to heat up and solder this board again, using a lot of flux in this area. Sometimes such a rework works. Sometimes it does not. Depends on how the melted solder forms balls and the surface tension...
