Hi team,
We installed a sdio interface WIFI module on the Pico Max, and also porting the driver to the kernel.
It works fine for sdio 1 wire. But as long as we use 4 wire sdio, the SDIO R/W error occurs.
Could you please give some advice about the possible reason for this case?
WIFI module on pico max
Hello, we have no plan to adapt the wifi module to the SD card slot of pico max, we can't be sure if your hardware design is correct and matches our design.
So we have not encountered a type of situation, unfortunately we can't provide relevant advice.
In the past, some members of the community have adapted RTL8723bs and used 4-wire SDIO drivers, and we have not continued to maintain after the subsequent SDK update, you can refer to https://blog.csdn.net/qq_28877125/artic ... /133148418
