Hello, L4 hackers!
I use Pandaboard for my practising with Fiasco.OC and L4Linux.
1) I got a problem with booting L4Linux with my own ramdisk. When I use 18 mb ramdisk, I got the following error:
24691072 bytes read
## Starting application at 0x81000000 ...
,,,[Everything is usual]
NET: Registered protocol family 17
List of all partitions:
No filesystem could mount root, tried: ext3 ext2 ext4 cramfs

To make ramdisk I simply create a file, write 18 Mb of zeroes to it (with dd), create in that file ext2 partition and copy there files from ramdisk-arm.rd
So, what should I do to get a proper working ramdisk?
2) Even more. If I create 20 mb ramdisk, I got this:
26788224 bytes read
## Starting application at 0x00000000 ...
Than the booting hangs. Why so?
Looking forward for your help, guys!
