Hi, I make my student research project my aim is running petalinux v0.40 on a microblaze XUPV2. My Hardware is running fine, but i have problems with my romfs.I start the board and push the image.elf in my ram and I get this KernelMessage: Linux version 2.6.20-uc0 (t...@tool) (gcc version 3.4.1 ( PetaLinux 0.20 Build -rc1 050607 )) #8 Thu Oct 22 13:55:38 CEST 2009 setup_cpuinfo: initialising setup_cpuinfo: No PVR support in CPU.

So I check if my romfs is in my image.elf microblaze-uclinux-objcopy --add-section=.romfs=software/petalinux-dist/images/romfs.img --adjust-section-vma=.romfs=0x901ab000 --no-adjust-warnings --set-section-flags=.romfs=alloc,load,data software/petalinux-dist/linux-2.6.x/linux software/petalinux-dist/images/image.elf BFD: software/petalinux-dist/images/image.elf: warning: allocated section `.romfs' not in segment microblaze-uclinux-objdump -x software/petalinux-dist/images/image.elf |grep romfs 32 .romfs 001e6c00 901ab000 901ab000 001a694d 2**0 00000000 l d .romfs 00000000 901656b4 l O .text 00000004 __exitcall_exit_romfs_fs 901a7d34 l .init.text 00000034 exit_romfs_fs 901a91d4 l O .initcall.init 00000004 __initcall_init_romfs_fs6 901a2228 l .init.text 00000084 init_romfs_fs 90188bf4 l O .data 00000020 romfs_fs_type 900b3c78 l .text 0000002c romfs_get_sb 90188c14 l O .data 0000004c romfs_ops 900b3ba8 l .text 00000038 romfs_alloc_inode 900b3be0 l .text 00000030 romfs_destroy_inode 900b39a8 l .text 00000200 romfs_read_inode 900b3008 l .text 00000064 romfs_statfs 900b3c64 l .text 00000014 romfs_remount 90177780 l O .rodata 0000003c romfs_aops 900b37a4 l .text 00000204 romfs_readpage 901777bc l O .rodata 0000006c romfs_dir_operations 900b33c0 l .text 000001d8 romfs_readdir 90188c60 l O .data 00000054 romfs_dir_inode_operations 900b3598 l .text 0000020c romfs_lookup 90188cb4 l O .data 00000020 romfs_modemap 90188cd4 l O .data 00000008 romfs_dtype_table 900b2e0c l .text 000001fc romfs_fill_super 900b306c l .text 000001a8 romfs_strnlen 900b3214 l .text 000001ac romfs_copyfrom 901ba20c l O .bss 00000004 romfs_inode_cachep 901ab000 l d .romfs 00000000 90000990 g .text 000000a8 get_romfs_len 90000980 g .text 00000010 get_romfs_base Thank you for your help.
