Message-ID: <8cad0aa0901210815q730730e7md31f32900ea4c1e5@mail.gmail.com> (raw)

I am now trying to use an initial RAM filesystem.
I have this:
"checking if image is initramfs... it is"
And then, after some hardware detections:
"List of all partitions:
1f00 8192 mtdblock0 (driver?)
No filesystem could mount root, tried: ext3 ext2 cramfs
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0)
Rebooting in 180 seconds..."
When using a NFS root file system, it is ok.
I have passed these args to my kernel:
bootargs root=/dev/ram ro init=/linuxrc noapic acpi=off nofb
I tried also root=/dev/ram0 but it is not working better.
My kernel .config contains:
CONFIG_BLK_DEV_INITRD=y
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=16
CONFIG_BLK_DEV_RAM_SIZE=8192
Do I need to have MTD_RAM = y ?
Is there any other thing I should set to Y for it to work ?
Thx & Regards,
JM
