Issues flashing esp32-S3 on Adafruit Qualia board

[karunt]

When I try to flash a project (idf.py flash monitor --port COM3) on the esp32-s3 chip mounted on an Adafruit Qualia board (using the ESP-IDF environment), the build happens successfully, but then the program doesn't execute, or at least the monitoring of it doesn't seem to happen. Here's the output I get after the entire code is written to the chip:

It stays stuck at

until I manually kill the command. Any idea what might be going on and how to resolve this situation?

"waiting for download," is likely related to a mismatch in the COM port settings or a problem with the board configuration. In your output, you flash the device on COM3 but the monitor attempts to connect to COM4.

@liaifat85 - Apologies for the typo - I indeed flashed it to COM4. No issue with the port there. Anything specific about the board settings I ought to look out for? I'm not familiar with the Adafruit Qualia board, but it's one that comes with a built in connector for a LCD screen. I've been working mostly with ESP dev boards, so this is new territory for me, and I can't find any other guidance online.

Turns out that ESP-IDF is simply waiting for user to hit the Reset button on the Qualia board to begin executing the program on it. The Qualia board requires pressing of the Reset button to launch new firmware on it. That solved my problem.
