Hi - Just getting started with VisualMicro on ESP32. I can get it to work fine with serial debug, but am struggling with hardware debug on Windows 10.

I'm using a TIAO USB Multifunction Board. I believe I've got the JTAG connector wired to the correct ESP32 pins. I think I should be using the TUMBA config script, but I couldn't find how to select that script. So I copied the TUMBA config script ("/ftdi/tumpa.cfg") to "/ftdi/minimodule-lowcost.cfg" and selected that in VisualMicro.

Here's the output from Visual Micro after "Debug>Attach to process"):

Starting: "C:\ProgramData\vmicro\tools\openocd-espressif-esp32-10.0.1\bin/openocd.exe" -d2 -l 32_node32s\Debug/JayzVisualStudioTestSketch.ino_DebugOpenOCD.log}" -s s/" -f s/interface/ftdi/minimodule-lowcost.cfg" -c "set ESP32_RTOS none" -f s/board/esp-wroom-32.cfg" -c "init"
Starting: lf-gcc\1.22.0-80-g6c4433a-5.2.0/bin\xtensa-esp32-elf-gdb.exe" --interpreter=mi -ex "set remote hardware-watchpoint-limit 2" -ex "mon reset halt" -ex "flushregs" -ex "thb app_main" -ex "c"
"C:\ProgramData\vmicro\tools\openocd-espressif-esp32-10.0.1\bin/openocd.exe" exited with code 1 (0x1). 

Can anyone tell me if this looks like a driver issue, or if I've selected the wrong script, or anything else about how I should go about getting things to work? The "exited with code 1" error message doesn't give me much direction...

Thanks...

Yes, here it is:

More info: I used the driver that was pointed to on the DIYGadget site where I purchased the TUMPA (TIAO Universal Multi Protocol Adapter): TIAO_TUMPA_CDM_v2.12.24_WHQL_Certified

Also, I should mention I'm using X86 Windows 10, if that is an issue (Version 10.0.18362 Build 18362).

Thanks so much! Installing the suggested driver got things working.

To get the TUMBA board to work, I copied the TUMBA config file contents to the F2232 Mini Module config file so that I could select it from the Visual Studio menu. How could I make the original TUMBA.cfg file appear in that menu, so I don't have to perform this minor hack?
