Hi, my Ke02Z showed as an external drive with the proper label so I held down the reset and plugged it in to enter bootloader mode. Then I dropped in some of the .srec precompiled example files, repowered and they didn't work as they were supposed to. Now it's stuck showing bootloader as the name of the external drive. The green led blinks 8 times, then stays off for 3 seconds and repeats. Have I bricked my poor little Ke02Z? Is this some kind of error mode? How do I get back to normal operation?
