Problem programming ESP32-WROOM-32 on own designed PCB
Posted: Mon Sep 21, 2020 1:29 pm
For programming I used the following steps (https://docs.espressif.com/projects/esp ... t-up-tools). I'm using for uploading J-Link in the command line and I receive in the command line programming and verify went OK (see added picture "command-line"). But the code isn't running on the ESP32, what do I wrong?
But when I upload the code to an ESP32 devkit V1 it works fine and the result in the command line is the same.
The RX and TX from the ESP32 on my own designed PCB are connected to another microcontroller (see added picture "schematic"), can this cause any problems?
I'm using the TDI, TDO, TMS and TCK also connected the 3.3V and GND.
