I have exactly the same problem mentioned in this post : https://www.ghielectronics.com/community/forum/topic?id=12398
But all answers that I read in this forum have not solved this problem.
Device version from FEZ Config :
Loader (TinyBooter) Version: Firmware (TinyCLR) Version: 18.104.22.168
I follow these instructions https://www.ghielectronics.com/docs/112/g400 to update TinyBooter, I don’t see any COM Port in the Device Manager but I have “Debugging interface …” and in Printers and Device, there is G400.
I have tested on 3 different computers Win 8 x64 and 2 others Win7 x64 with sam-ba installed. I also tried to reset the board without success.
Any ideas to solve this issue ?
Thanks for your help
