I am using CHERTS unofficial DevKit. My flash is using dio. I did not touch anything on the SPI speed. How do I find out what is the SPI speed used?

Could you duplicate the problem on your side by doing a fresh flash again? It will be easier for you to troubleshoot that way.

I added some text effects like scroll in the SSD1306 example (latest SMING version) and flashed to a nodemmcu board v0.9 connected with a I2C screen.

Aftert flash, the screen (and esp) works fine, but if I power off and power on (dettach and attach usb cable from pc) it begins to give the following error, rebooting again...again... until I have to flash again to work fine.
