that has an error “[ 813.366261] sdhci-tegra 3400000.sdhci: error -19 in autocal-pu-pd-offset settings”
I ignore it and use “fdisk /dev/mmcblk1” add a new partition that also has same error “sdhci-tegra 3400000.sdhci: error -19 in autocal-pu-pd-offset settings” then I input n,p,w to add a new partition. finally it has “/dev/mmcblk1p1”.But when I mount this block by “mount /dev/mmcblk1p1 /mnt” it reminder me as below:

[ 1590.029810] sdhci-tegra 3400000.sdhci: error -19 in autocal-pu-pd-offset settings
mount: wrong fs type, bad option, bad superblock on /dev/mmcblk1p1,
missing codepage or helper program, or other error

   In some cases useful info is found in syslog - try
   dmesg | tail or so.

and “fdisk -l” show:

Can someone help me.What the error " sdhci-tegra 3400000.sdhci: error -19 in autocal-pu-pd-offset settings",and why I can’t mount this block.

Hi zhangbaofeng,

I tried to new partition and mount /dev/mmcblk1p1 to /mnt are no problem.
I think you can try to format your SDcard to FAT format and try again.

Thanks!

It sounds like this is custom eMMC wired to the SD card interface, and not really an SD card. If this is the case, then perhaps there are other settings involved.
