SWD ERROR on C027 when trying to flash it with a binary
I have flashed the C027 several times in the last days and everything works fine. But now I'm not able to falsh any binary on the device. Whenever I copy a binary file to the device, the device will shortly disappear and after this the C027 contains the error file "fail.txt" with the content: "SWD ERROR". Several seconds later the C027 disappears again from the explorer and the fail.txt contains now: "TIMEOUT". This last step will infinite repeated.
So far I have tried (unsuccessfully):
different USB Cables different Power Supplys Windows 7 and Windows 10 arbitrary binaries
How can I fix this issue? Why is this happening?
