Hi Simon, i'm using a ESP32-S3 DevkitC-V1.1 board and there is a issue about the JTAG for upload/debug.

I have some dubts about wiring between ESP_PROG and Target board.

There is a issue about the e-fuse? 

my connections are:
https://www.visualmicro.com/page/ESP32S3-JTAG-Debugging.aspx

at this time I have not changed the fuses, they are still the original ones. Should I change them?


the output is this:
Program size: 663393 bytes (used 51% of a 1310720 byte maximum) (6,85 secs)
Minimum Memory Usage: 43088 bytes (13% of a 327680 byte maximum)

Hi Simon

Hi simon
in attach the 2nd efuse report.

[SOLVED]
Hi Simon, I made the change on the eFuse, it is now TRUE. Then I brought GPIO3 = LOW with a jumper, aswell as it works fine is you left open GPIO3. Everything works!

I would like to point out these things to keep in mind:
1.) if you connect ESP_PROG in a different PC USB, the win11 driver SW does not see it. It only works on a specific USB port.

2) the JTAG connections for the ESP32-S3 devkit1.1 board indicated in your page are wrong. you show the pinout on the TOP side of the board, but if you turn the board BOTTOM side, you will see that the nice Chinese have a different pinout you have to follow the one on the bottom side. The Chinese will hardly become masters of the world if they keep doing things like this!!!!
