Hi all,

we have own PCB based on the G400-S module and suddenly I have received an unhandled exception generated during uploading new application.
I am not sure what was changed because I have uploaded such application a lot of times without this exception and the same application runs OK on the Raptor without any problem.
We do not have any display connected to the G400-S in our PCB so I do not know why the exception is connected with display.

Have you already seen this type of exception?
I do not know how to get rid of it. I have tried to erase application, firmware and TinyBooter and install everything again from scratch(using SAMBA) and there is still the same exception generated when connected with VS debugger. It seems that application runs OK when PCB is reset and not connected to the VS debugger.

@ mhstr - Does it persist if you deploy an empty application after reflashing the board? Are you flashing the config.hex file as well?

3

@ John - Not sure as I have uploaded the same application after re-flashing TinyBooter and TinyCLR.
It is true that I have flashed only firmware.hex not config.hex.
I will try it again next week because right now I don’t have this PCB at home.

4

@ mhstr - I believe that flashing confix.hex is required.

5

@ John - You are right. After flashing Config.hex the exception disappeared.
Thanks.
