Robin,

I am assuming that you are using uClinux with 'romfs' as your rootfilesystem. If this is the case, you should create your 'uImage' with 'image.bin' and not 'linux.bin'. The 'linux.bin' is just the kernel and does not include the romfs image in it.Also noticed that u have given "root=/dev/mtdblock" as kernel command. Are you placing your 'romfs' image at that address ? Another point of note is your Flash memory space, which Iis just 4MB. I am assuming you are 'bootm' ing your image from Flash address.Is your uImage size bigger than that by any chance ?

Wolfgang:

Sorry - I was not trying to make a bug report - just ask a quick question if anyone else had seen any issues with large (5.5Meg binary images) being turned into large (3Meg) gzip files.

Here is the full description (sorry for the previous typo):

make a kernel that includes a large file in the romfs (we are using mp3 file - so it is fairly uncompressible - not sure if this is the issue or not). When this mp3 is not included the romfs, uImages (and bootm) continue work OK.

to make the bin: bfin-elf-objcopy -O binary linux linux.bin

to creat the gzip: gzip -9 linux.bin

to create the uImage: (WORK_DIR)/u-boot_1.1.3/tools/mkimage -A Blackfin -O Linux -T kernel -C gzip -a 0x1000 -e 0x1000 -n "Bfin uClinux Kernel" -d linux.bin.gz uImage

I have three files linux (elf file) linux.bin (binary) and uImage (compressed)
