Discussion - Software / Re: Cannot flash a firmware via VNC2 Debug Module
« on: February 18, 2020, 04:30:51 AM »

Okay, I was using VNC2 Debugger with VCP driver.
I need to use D2XX drivers but it may disable any software using COM ports, right?

So does it means that I need to rewrite VID/PID on the EEPROM on VNC2 Debugger?
Would you teach me the way to do it or give any documentations?

>Can you also try programming directly within the IDE?

It also doesn't work correctly...

Thank you for your information! I will consider about using FT90x series.
But now I need to use VNC2 for the prototype of new product...

I'm developing V2DIP1-3D with VNC2 Debug Module.
But they don't work correctly...
I cannot flash a firmware via the debugger.

I tried FT_Prog and V2Prog, but both failed with errors.
Did I miss something?
