Seems to fail in esptool.py too, but with timeout error (very quickly so must be very small timeout)

esptool_offline_log.txt

Offline log includes --trace equivalent of:

If I use --no-stub offline then it appears to be happy:

Can confirm it works fine in windows 11 using esptool-js.
We've had users reporting similar now too.

@brianignacio5 got a mac issue for you here, using the mini-1 modules of ESP32.
I tried using esptool 4.9.0 via pip install --upgrade --pre esptool on the mac and same broken result.
There is a mac update waiting for me, I'm on the macOS Sequoia Developer Beta for my Beta Updates to macOS.
I'm currently on 15.3 Beta (24D4034f). The Update is 15.3 too but no idea which release tag

Maybe worth noting the python version of esptool reports the chip revision as rev 3.1, whereas esptool-js just rev 3

Mac WCH Driver issue, just need to enable the driver extension via settings, see this post / video:
