espefuse.py stuck

[youngjun]

Hi,
I'm implementing custom board using ESP32-S3-WROOM-1.
I'm trying to download the firmware using esp prog.
The problem is that when I run espefuse.py on cmd, nothing is output in a stopped.

Code: [Select all] [Expand/Collapse]

1. python espefuse.py -p COM11 summary

The python is included in esp-idf. (version 3.11)
In vs code, [get eFuse summary] can read efuse status.

I'm using UART(TXD0, RXD0 pin) to read eFuse.
My OS is windows 10 64bit.

Does anyone know why espefuse.py stopping?

It was a comport driver error.
I deleted all the drivers, and the problem was solved.
