Nano clone with CH340

I am unable to debug a Nano clone using a CH340 instead of the usual FTDI.   

Should I be expecting this?

If I set a tracepoint (no break) and build/upload DEBUG profile (automatic debugging is on) the program appears to halt (as though on a breakpoint). In the meantime the vMicro debug trace screen shows "Launching debugger" but nothing subsequently happens.


Am I able to debug these boards?  If not, I can switch to a genuine UNO since i only use these as a cheap alternative but it would be nice to be able to work with them directly.


Cheers,

Jason.

Hi,

The debugger just uses standard serial. So you should set the tool bar to Release and try your own serial at 115200 to see if it works.

If you can send serial to the monitor with println("Hello World") then debug should work okay with trace points. If you can send a serial message from the monitor and receive on the arduino with serial.available() and serial.read() then break points should also work.

If the standard serial does not work then try at a lower speed
