Simple stand-alone debugger for AVR DebugWIRE chips connected directly to an FT232R/CH340/DigiSpark/LittleWire on Linux or Windows.
Hi! I'm using ATmega48PA + FT232R + diode. `dwdebug f0` founds baud, correctly read signature but stucks at WriteDebug error. After debugging I found that it stucks at `DwGetRegs(first=28,count=4)` that...
I just finished testing dwdebug with a tiny13a running off the internal ~9.6Mhz oscillator. The baud rate was ~72kbps, or a bit time of 13.9uS. Using a 1n4148 diode connected...
Hi, I got my ft232 converter finally.I give it a try but unfortunately I get the following error. I enabled the debug-wire on my device (lfuse:0xE2 hfuse:0x9F) ``` sudo ./dwdebug...
Very nicely done :) I never got around to integrating the protocol with a debugger. It seems like your usb-serial adapter got a pullup builtin because without a 10k pullup...
I have a ATtiny84a. Everything worked until I tried to upload new code via debugwire: ``` Unconnected. > device tty.usbserial-AH06TDUZ Connected to ATtiny84 on /dev/tty.usbserial10 at 30949 baud. fffffffe: ffff...
There used to be a 30ms interval between 2 debugWIRE access.  It seems dwReadBytes wait 23ms after receiving the last byte. ...
Works fine with ATTiny13A and CP210x. But doesn't work with ATTiny44A, because when tried to connect I got this message: ``` Unconnected. > device com5 WriteDebug, byte 1 of 1:...
This is a report that I successfully run dwire-debug on cheap PL-2303HX USB-UART dongle. Through gdbserver run by dwire-debug, I was able to attach gdb and load/execute(continue) the code on...

Similarly DwSend(Bytes(0x64)) on line 144 is also redundant since the following DwOut call...
fuses?
Dave, this tool is already very useful. Do you think it's possible there's a way to use debug wire to change fuses? If so, after initially enabling debug wire, it...
