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: reading image.elf 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 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(1,0) CPU: 0 PID: 1 Comm: swapper Not tainted 3.13.0-l4 #1 [<0200c624>] (unwind_backtrace+0x0/0xec) from [<020054c0>] (show_stack+0x10/0x14) [<020054c0>] (show_stack+0x10/0x14) from [<0222e63c>] (panic+0x7c/0x1b8) [<0222e63c>] (panic+0x7c/0x1b8) from [<022f2c40>] (mount_block_root+0x25c/0x29c) [<022f2c40>] (mount_block_root+0x25c/0x29c) from [<022f2f44>] (prepare_namespace+0x160/0) [<022f2f44>] (prepare_namespace+0x160/0x1b4) from [<022f2894>] (kernel_init_freeable+0x1) [<022f2894>] (kernel_init_freeable+0x174/0x1b8) from [<0222ccf0>] (kernel_init+0x8/0x118) [<0222ccf0>] (kernel_init+0x8/0x118) from [<020077d4>] (ret_from_fork+0x14/0x20) [<020077d4>] (ret_from_fork+0x14/0x20) from [<00000000>] ( (null)) panic: going to sleep forever, bye 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: reading image.elf 26788224 bytes read ## Starting application at 0x00000000 ... Than the booting hangs. Why so? Looking forward for your help, guys!
