[    1.279362] sdhci_msm 7864900.sdhci: No vqmmc regulator found
[    1.279759] mmc0: SDHCI controller on 7864900.sdhci [7864900.sdhci] using 32-bit ADMA in legacy mode
[ 7281.356236] mmc0: new high speed SDIO card at address 0001

i remember i saw the following when the SD card is connected successfully:


root@swi-mdm9x28:~# dmesg | grep 'mmc'
[    1.072562] sdhci_msm 7864900.sdhci: No vmmc regulator found
[    1.072576] sdhci_msm 7864900.sdhci: No vqmmc regulator found
[    1.072941] mmc0: SDHCI controller on 7864900.sdhci [7864900.sdhci] using 32-bit ADMA in legacy mode
[    1.200555] mmc0: new high speed SDHC card at address e624
[    1.208729] mmcblk0: mmc0:e624 SU08G 7.40 GiB
[    1.210479]  mmcblk0: p1
root@swi-mdm9x28:~#

After that I can mount SD card by the following commands:

mkdir -p /tmp/sdcard
/bin/mount -t auto -o sync /dev/mmcblk0p1 "/tmp/sdcard"
