SD card not recognized by ubuntu(armhf)/xfce

Former Member
Former Member over 12 years ago

Hi community,
i copied the ubuntu file system and boot files to SD card (fat32 and ext4 partition), similar to http://www.wiki.xilinx.com/Ubuntu+on+Zynq, (but without initramfs).

Now i would like to modify the files on the fat32 partition, but the mmcblk0p1 (and 2) do not show up in /dev.

dmesg | grep mmc
mmc0: no vmmc regulator found
mmc0: invalid maximum block size, assuming 512 bytes
mmc0: SDHCI controller on e0100000.sdhci[...] using ADMA
mmc0: new high speed SDXC card at address aaaa
mmcblk0: mmc0:aaaa SU64G 59.4 GiB
mmcblk0: p1 p2
EXT4-fs (mmcblk0p2): mounted filesystem with ordered data mode. Opts: (null)

the output is the same like with other linux implementations...the only difference, mmcblk0p1 and p2 show up in /dev.

Can you tell me, what is the problem there? why is mmcblk0p1 not showing up? Are there other ways to mount the sd card?
the card also doesn't show up in df -h....

thanks in advance for every hint.

    Do you know the maximum size of SD card actually supported? I think ZNYQ officially supports SDHC and that some SDXC cards have backward compatibility. So officially SDHC tops out at 32GB, but you have got a 64GB SDXC card running.
