Wifi over SDIO on P4

[JohnnyZ]

Try it without SD card, and it will work. Or specify SDIO1 (slot 0) because examples use same SDIO2 for both SD card and SDIO WIFI.

Code: Select all

    sdmmc_host_t host = SDMMC_HOST_DEFAULT();
    host.slot = SDMMC_HOST_SLOT_0;

I have tried, but no luck yet.!

I get the following error message.

E (587) sdmmc_io: sdmmc_io_rw_extended: sdmmc_send_cmd returned 0x107
