I have an ESP32-S3-WROOM-1-N8R2 on a custom board with a JTAG connector.
The JTAG connection is the following to the chip:
- jtag1.png (36.15 KiB) Viewed 470 times
- jlink2.png (10.95 KiB) Viewed 470 times
In the ESP-IDF configurations, I am creating the basic "hello world" project, where in "Choose ESP-IDF Board" I select ESP32-S3 (via ESP-PROG). I have done no extra configurations in the SDK Configuration editor, and all settings are the default ones. The pin header for selecting the power supply on the ESP-Prog is set to 3.3V.
When I flash the code, I have the following output:
Code: Select all

Project build complete. To flash, run:
ESP-IDF: Flash your project in the ESP-IDF Visual Studio Code Extension
or in a ESP-IDF Terminal:
idf.py flash
or
idf.py -p PORT flash
or
python -m esptool --chip esp32 -b 460800 --before default_reset --after hard_reset --port /dev/ttyUSB1 write_flash --flash_mode dio --flash_size 2MB --flash_freq 40m 0x1000 bootloader/bootloader.bin 0x10000 project-name.bin 0x8000 partition_table/partition-table.bin

Also, after flashing the code and trying to open the serial monitor to see the "Hello World", nothing shows up. Even after a reset of the device, I get nothing on the serial monitor.
I am not sure why I am getting the warnings and errors in the beginning when flashing as well. Does anyone have an idea what could be causing this?
Does anyone know what the issue could be with this? Is there something extra that I need to put as configurations for this board? Or something hardware related to the JTAG interface?
