Not working with RPI4

[waynewu411]

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?

Unfortunately I don't have a 4b to repro with, and given that the SDIO interface changed on this latest SoC I'm not surprised that it doesn't work.

I'll leave this open in case anyone else wants to take a look.
