Hi all,
while trying set up a live system booting from a build in cardreader in an
acer one 110 I run in the following problems:
I put the kernel and initrd.img into the boot-partition on the harddisk (ssd)
because the cardreader isn't bootable.
But unfortunately the the initrd-scripts could't find the live image on the
cardreader device.
The cardreader device is correctly recognized by the kernel an the sdcard
gets the devicenname mmcblk0. The first partition: mmcblk0p1.
But in any way the cardreader doesnt't behave like another block device. I
thought it could be because of the strange numbering of partitions like
mmcblk0, mmcblk0p1 instead of mmcblk0, mmcblk01 - according to sda, sda1, ...
After booting the initrd-scripts tries to find a live image in the /dev/sda
partitions but after a while I get a shell from initrd. Via shell I can mount
the parition e.g. mount -t ext2 /dev/mmcblk0p1 /mnt - for me the evidence
that the block device is correctly recognized and works.
So far I tried to identify the part in the initrd-scripts where the
block-devices are inspected. But without result.
Also I tried to make only one partition in the device so mmcblk0 is already
the blockdevice where the image is in the subdir /live.
Now the initrd script fails with the error:
panic No supported filesystem images found at /live.
Any Ideas?
How to modify the initrd in a way that also mmcbkl0p1 is queried for the live
filesystem?
