Can't connect to device #55
Description
Hello! I can't connect to my ATMega328p. Yesterday I accidentially enabled DWEN (fused 0x99 in hfuse) and now I'm trying to disable it.
I installed dwire on Windows into Cygwin, but got next error:
$ ./dwdebug device COM5
COM5 ...Warning, expected to read zero byte after break, but got $e0.
Cannot find requested device.
I'm using CH340 and connecting VCC, GND, RX and TX (last two via 1n4007 diode to RST pin).
Can anybody help me — I don't understand what I'm doing wrong. Is it possible that pullup resistor on reset pin breaks debug wire?
