Documentation: Proposal for warning: Incompatibility Issue with some wrover boards

[dierochade]

there are incompatible wrover boards, that give you flash errors and/or only boot when holding the boot hardware button.

This was discussed here (#182) and closed as resolved, but according to recent reports in this thread, it is still unsolved, at least for some users.

I have bought these: https://aliexpress.com/item/1005005885233367.html

And I also experience fatal errors on bootup, after flashing with the normal webtool:

I would suggest to issue an warning in the documentation or recommendation for compatible boards for the time being?

Just a heads up. I discovered that Tasmota32 Cam using the web programmer (https://tasmota.github.io/install/) boots without issue. The previous issue matches the same board I tested. Tasmota boots and the camera works. There might be something wrong with this (16 bits) project, that Tasmota (32 bits) solves.

The boards factory image:
