uBlox C-027 SWD ERROR
I've been tricking with a few ubloxes c027 and after flashing a specific code (just one HTTP sample code from the mbed library) both my uBlox won't flash at all. It just keeps returning the fail.txt with the SWD ERROR whatever code I try to flash.
Now the LED1 (red) keeps turned and it doesn't work at all. I've tried changing the power supply (even powering through the side connectors) and nothing.
