What is the Expected Behaviour?

Flashing without error (warning in this case, as the flashing works)

More Information

Having an issue with esptool since upgrading from 4.1. Same error was present in 4.2 and recently upgraded to 4.3 and this did not rid of the issue. Therefore I'm reporting this in case anyone else has the same issue.

Note that this does not prevent flashing and neither an operational issue. Both the flash and application functions correctly. Just a nuisance really and can't figure out what cause it.

Error occurs for C2, C3 and S3 modules. Addition note: Esptool 4.1 works perfectly fine. This error does not occur. (e.g. environment: ESP-IDF 4.4.2 and Esptool 4.1)

dobairoland commented 2 years ago

Hi @GTCLive. ESP-IDF 4.4.2 is bundled with esptool==3.3.x. Esptool v4.0 is not supported there. This should be a wrongly setup environment for Eclipse. Please report the issue for the eclipse plugin. Actually, the reported backtrace is not happening from esptool. Esptool doesn't use asyncio.
