Hi,
MPC852T target board with 8MB flash, which kind foot file system is the
best selection among of:
1. Cramfs
2. EXT2
3. JFFS2
4. RAMDISK
Thanks advance!

During creating jffs2 ,I modified the file /drive/mtd/maps/rpxlite.c just
like the file tqm8xxl.c,I refered the manual DULG.after loading and running
the kernel,display some following message:
init_rpxlite_mtd: chip probing count 0
request_module[cfi_cmdset_0002]: Root fs not mounted

Hi,
Our board was bought from a company. This company use TQM823L board
files in PPCBoot 1.1.5 as a model and it made some changes accroding to
their hardware connections(but these changes are trivial). And the pc
card voltage is 3.3V.

I understand that your board is neither a rpxlite nor a TQM8xxL - so
which

Hi,
in some elderly code for a VME-supporting 824x-board from
our company I found the following line in ppc_md.setup_io_mappings():
io_block_mapping(0x8000, 0x8000, 0x1000, _PAGE_IO);
This is obviously meant to map a window of VME IO memory into
virtual address space. What puzzles
Because our board will be turned on and off frequently, so I think high
stability is the important, and a R/W file system is prefer selection
too! Another performances such as speed of booting is not the focus!
Now our system can runs ok, I use EXT2 FS as the root file system build
in a 32M

How about speed when
Just to add to Wolfgang's comments, turning off power without warning is not
simply a file system problem. It is a hardware problem that NO file system, no
matter how robust it is, can survive. The memory chips (flash, EEPROM,
battery backed RAM) require a finite amount of time to actually
I am using the linuxppc_2_4_devel tree from http://ppc.bkbits.net/ and a
ramdisk which I downloaded from Wolfgang Denx's FTP site. The compile
environment is the latest ELDK. I have this tree and ramdisk working just
fine on an MPC8260 processor. I took that support and changed a few lines

I sent a message earlier today about getting a swap_dup: Bad swap file
entry 0e18d55c error. I found the problem and fixed it and wanted to share
it with people who are still learning this stuff, like myself.
After 2 days of pounding on my head I found the file

I still have so more to do like verifying FEC and PCI. Also I did it on 2.4
which I believe is done or close to being. I can provide a patch when I am
done.
