Re: [ts-7000] Re: config file for TS7200 and linux kernel 2.6.29 ?

[Balaji Ravindran <>]

Hi

This is where I get confused actually. My compressed vmlinux is 1.7 MB, and uncompressed is about 30 MB,so basically when I load the compressed one, kernel gets uncompressed to 30 MB, so that should be fine given the fact that I have 32 MB SDRAM on my TS7200.

Now, when it comes to compact flash. I have formatted my CF to ext2 (using gparted), and I mount it, and copy the debian rootfs to my mounted partition.

Yesterday a weird error happened, if I copy paste, my mail goes to sppam, so I will just type here.

It said, Kernel Panic – failed to mount root file system using ext3, ext2, mtdblock1

Before this line, I saw the log saying it identified my SanDisk CF, and found hda1.

Now, the question is, in my Host(where I compile my kernel), my CF is mounted as sdb1. And in my target(ts-7200) is it sdb1 ? Or hda1 ? Whats the difference basically? Why does it use different block device file system names.

Thanks

Secondly check that you have setup your root filesystem properly ? I used compact flash partitioned into a boot partition(mkfs.ext2 -I 128 /dev/sda1) and the rest for root file system (mkfs.ext3 /dev/sda2). What is your filesystem on CF.

It did uncompressing linux, and did not proceed any further. No error nothing. What could be the problem? Has anyone encountered this before?
