Hi @feelfreelinux,
Thanks for reporting this. Are you using a ESP32 "Core" board with onboard USB?
Can you post the full esptool.py command line and output from esptool.py, please? If you're using a make flash type target, you can run make flash V=1 to see the full command line.

We've reproduced this bug internally and there's a fix on its way.
In the meantime, you can ignore the error - the data is flashed 100% successfully in both cases.

This should be now fixed in master. Please do a git pull origin master followed by git submodule update to get updated esptool.py.
