Hi, everyone!
I'm a bit confused about the flash chip and the partitions on it so i'm
hoping than someone out there knows what is what.
During normal boot '/dev/mtdblock1' is used as boot device. After a
NFS-boot I can mount /dev/mtdblock/1 which is then equal to the content
of the '/dev/mtdblock1' partiton. This indicates that the ~30Mb linux
device is actuallt partition1 of the flash device.
In the documentation and from the boot messages from the kernel the
following information is given.
>> Creating 3 MTD partitions on "NAND 32MiB 3,3V 8-bit":
>> 0x00000000-0x00004000 : "TS-BOOTROM"
>> 0x00004000-0x01d04000 : "Linux"
>> 0x01d04000-0x02000000 : "RedBoot"
This indicates that 256Kb is "TS-BOOTROM", ~30Mb is for "Linux" and ~2Mb
is RedBoot.
>From "fis list" i get the following:
>> (reserved) 0x60000000 0x60000000 0x01D04000 0x00000000
>> RedBoot 0x61D04000 0x61D04000 0x00040000 0x00000000
>> vmlinux 0x61D44000 0x00218000 0x000A8000 0x00218000
>> RedBoot config 0x61FF8000 0x61FF8000 0x00001000 0x00000000
>> FIS directory 0x61FFC000 0x61FFC000 0x00004000 0x00000000
Which indicates that, flash adress space starts at 1.5Gb, first we
have ~30Mb reserved space, then 256Kb RedBoot followed by 670Kb vmlinux
and the 4Kb of RedBoot config and 16Kb of FIS directory.
I'm confused, how are all these figures connected?
