Hello @Alaa-Aim, can you please invoke ESP-IDF environment in your terminal and try to run openocd -f board/esp32-bridge.cfg?

@Alaa-Aim is it possible that you either have selected wrong pinout when flashing esp-usb-bridge or wrongly connected the target to esp32s3?

@Alaa-Aim is it possible that you either have selected wrong pinout when flashing esp-usb-bridge or wrongly connected the target to esp32s3?

@Dzarda7 , I Tried to import the project (https://github.com/espressif/esp-usb-bridge)to Espressif-IDE , But I had no luck, so I used ESP-IDF 5.3 CMD, as below :
1- idf.py set-target esp32s3
2- idf.py menuconfig
3- idf.py build
4- idf.py -p COM7 flash

I configured as below

[Dzarda7]

You have wrong pinout, the one you are setting using menuconfig refers to the one on ESP32-S3 and you need to connect it to the corresponding pins on ESP32 (MTDI, MTMS, MTCK, MTDO), as you can see the blue ones in the pin description.

So you mean I have to use the default configurations ? as shown below ?

and use the table below for connection

F:\Espressif\WorkPlace\esp-usb-bridge-1.1.0

from the official schamatic for Esp-prog 2 as shown below

am i right ?

[Dzarda7]

You do not really have to if you changed them in the menuconfig, also did you connect the ground? VDD is better to be separate, linear regulator on the devkits might not be powerfull enough to run both boards at the same time.

Yes, only GND and common, could you please guide me how to import the project ( [https://github.com/espressif/esp-usb-bridge] ) to Espressif-IDE ? so I can compile it using GUI ? I couldn't do that by myself.

[Dzarda7]

I cannot unfortunately, I have never worked with Espressif-IDE, I tried it now, but it did not really work properly on my machine. If you want, you can try VScode plugin.

@Dzarda7 , many thanks, I'll try use VSCode

@Dzarda7 I managed to import the project to Espressif-IDE, flash it and it worked ,

[Dzarda7]

@Alaa-Aim happy to hear that!
