Hello,

I have this output:

Uploading 'Blink' to 'WEMOS D1 MINI ESP32' using 'COM12'
esptool.py v2.6
Serial port COM12
___
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
esptool.py v2.6
Serial port COM12
___
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header

when trying to hardware debug my blink.ino example on my esp32 wroom d1 mini.

Connection is like in the two added pictures. I only missed the 3.3V connection because if I do there is nothing blinking at all.

I see my debugger FT2232H Mini Modul in my device manager and I also used the zading wizzard for setting up my driver. I downloaded the vtp driver available on

https://www.ftdichip.com/Drivers/VCP.htm ;

and run the setup wizard.

When I connect the debugger to esp32 modul also compiling with arduino ide gets failed.

Many thanks in advance for any help

Other picture and output with verbose in next comments

Thanks for the report, and all of the detail.

Have you made all of the power connections around the Mini Module itself from the datasheet?
These are also pictured here

I assume that COM12 on your machine is for the FT2232H Mini Module?
If Yes - to upload via the Mini Module, it needs to be selected as a Programmer from the vMicro > Upload > Hardware Programmer menu.

No problem and glad it has resolved the issue.

There are some additional links shown in the Output Window when you select the debugger with the connection diagrams and guides on the options to select.
