OK !! i have check 60000000 freq its stable for 2.4G and 5G wifi modes

&sd_emmc_a {
status = "okay";
// vim2 wifi dont work
// max-frequency = <50000000>;
// wifi work again but failed on 5G AP mode
// max-frequency = <100000000>;
// stable freq is 58823530
max-frequency = <60000000>;
};

Hi,

Thanks for debugging, it's really weird since "high-speed" should be limited to 50MHz, 100MHz is SDR-50.

timing spec: 0 (legacy) should be timing spec: 5 (sd uhs SDR50)

what is your kernel version exactly ?

Could you retry with the following in the sdio DT node :

         cap-sd-highspeed;                                                    
         max-frequency = <50000000>;

and

         cap-sd-highspeed;                                                       
         sd-uhs-sdr50;                                                           
         max-frequency = <100000000>;

and on either test cat /sys/kernel/debug/mmc0/io
