[ts-7000] YAFFS2 difference between compiled and installed kernel.

[Andrés Sebastián Nagy <>]

Hi.

        I have a problem booting a TS-7260 with a new kernel binary generated 
from
tskernel-2.4.26-ts11-src.tar.gz, with ADEOS path applied. I had to make some
changes in a file in the kernel tree to boot with yaffs2: ts7250.c, some
changes to offsets of the partitions. It is strange that the source files of
kernel shipped with the TS-7260 doesn´t match with the binaries installed on
it.

        After i changed the file, and some other configuration files (to use
YAFFS2, and not YAFFS) the kernel was ready and everything is working ok,
but i have a warning in boot (Bad eraseblock n at xxxx):

Searching for NAND flash...
NAND device: Manufacturer ID: 0xec, Chip ID: 0xf1 (Samsung NAND 128MiB 3,3V
8-bit)
Scanning device for bad blocks
Bad eraseblock 0 at 0x00000000
Bad eraseblock 1 at 0x00020000
Using static partition definition
Creating 3 MTD partitions on "NAND 128MiB 3,3V 8-bit":
0x00000000-0x00020000 : "TS-BOOTROM"
0x00020000-0x07d20000 : "Linux"
0x07d20000-0x08000000 : "RedBoot"

        The warnings are not present when i boot with the kernel already 
instaled
in the TS (that haven´t adeos, so it not usefull to me). After some googling
and research it looks like its a behaviour related with yaffs
implementation... unfortunatelly, there are no patchs for kernel 2.4.x (at
least, i didn´t found any patch).


Any help would be very welcomed.


Thanks in advance.
