Maybe it is something trivial, but still…
I have switched the debug interface of my EMX module to COM1 by setting LMODE high or unconnected (actually, tried both options, but with the same result).
COM1 pins are connected to USB UART TTL connector, external 3.3V power source is used to power the device.
Everything works fine while the USB connector is connected to PC (regardless if debugger is running or not). Once I disconnect it from PC or remove it, power off the device, then power it on again and let it boot, it does not start the .NET code at all.
When setting LMODE to low and using USB debug interface, the .NET code starts perfectly even if USB is disconnected.
I am using .NET Framework 4.1, GHI NETMF SDK 1.0.18. Firmware and TinyBooter are updated for this version (v.18.104.22.168 and 22.214.171.124 respectively).
Unfortunately, I have to use COM debug interface because I need the USB client functionality.
Had anyone ran into same issue?
Thanks in advance.
