SD Card trouble...

    Hello Everyone...


    I'm having trouble accessing the SD-Card... During boot the carddriver detects it, but throws an:


    mmc1: SDHCI controller on 2194000.usdhc [2194000.usdhc] using ADMA

    sdhci-esdhc-imx: probe of 219c000.usdhc failed with error -16


    anyone? ;) Tested different working cards of different sizes, but no success..


    Thanx in advance,

    jochen

    Hi,


    which release you are using? fsimx6sx-V2.1?


    Do you have your own baseboard or do you using our starterinterface?


    sdhci-esdhc-imx: probe of 219c000.usdhc failed with error -16 belongs to usdhc4 what eMMC means. Do you have a PicoCOMA9X with eMMC?

    Hi,


    sorry for delay. Can you share which variant of PicoComA9X

    • PCOMA9X-V2-LIN
    • PCOMA9X-V3-LIN
    • PCOMA9X-V3I-LIN


    Do you see the SD-Card in /dev/ directory. It should be mmcblkXYZ?

    Hello PJ...


    It didn't show up in the /dev... That was my main problem... But meanwhile I got it working... first I got rid of the #define CONFIG_PICOCOMA9X_EMMC in the picocoma9x.dts which solved the -16 error, but didn't solve the problem, that the SD card didn't show up in /dev... I also had to get rid of the #define CONFIG_PICOCOMA9X_SD_A_CD line and after that everything worked fine...;)


    But thanks anyways...;)
