Hello, I tried booting the large-memory ARM platform and kernel with the latest gem5 dev source code. The boot process dies with a "cannot open root device" error. I used the unmodified arm-ubuntu-natty-headless.img disk image. Any suggestions? Thanks!
My command line is; ./build/ARM/m5.opt configs/example/fs.py --machine=VExpress_EMM --kernel=vmlinux.arm.smp.fb.3.2 Terminal output is; Kernel command line: earlyprintk console=ttyAMA0 lpj=19988480 norandmaps rw loglevel=8 mem=1024MB root=/dev/sda1 ... Root-NFS: no NFS server address VFS: Unable to mount root fs via NFS, trying floppy. VFS: Cannot open root device "sda1" or unknown-block(2,0) Please append a correct "root=" boot option; here are the available partitions: Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(2,0) [<80015190>] (unwind_backtrace+0x0/0xf8) from [<803565ac>] (panic+0x64/0x190) [<803565ac>] (panic+0x64/0x190) from [<80460c80>] (mount_block_root+0x194/0x238) [<80460c80>] (mount_block_root+0x194/0x238) from [<80460e0c>] (mount_root+0xe8/0xf0) [<80460e0c>] (mount_root+0xe8/0xf0) from [<80460f64>] (prepare_namespace+0x150/0x18c) [<80460f64>] (prepare_namespace+0x150/0x18c) from [<80460954>] (kernel_init+0x170/0x174) [<80460954>] (kernel_init+0x170/0x174) from [<8000f5f8>] (kernel_thread_exit+0x0/0x8)
