Not working with RPI4 - Githubissues

Hi there,

I'm using this project to integrate an ESP8266 HAT based on https://hackaday.io/project/8678/instructions for three kinds of RPI hardwares, including 3B+, 3A+ & 4.

It works perfectly on 3B+ & 3A+.

On RPI4, the module failed during initialisation with the following message:

Can anyone have any suggestion on this issue?
