Hi All,
=09I am porting Linux on the custom board PMC8266 (having MPC8266
microprocessor) based on the ADS8260 board.I am using ELDK1.1.1 and
Linux2.4.24.
I am trying to load JFFS2 filesystem , the JFFS2 filesystem image is
at address 0xFC160000 and the flash size is 32mb
I am getting the following messages:-
physmap flash device: 2000000 at fc160000
CFI: Found no Physically mapped flash device at location zero
kmod: failed to exec /sbin/modprobe -s -k jedec_probe, errno =3D 2
kmod: failed to exec /sbin/modprobe -s -k map_rom, errno =3D 2
pmc8260 flash map (size->0x2000000 mem->0xFC160000)
CFI: Found no pmc8260 flash memory device at location zero
Can anyone please tell me what is happening and how can i set it right??

Hi Apoorv.
Is the Flash CFI complient?
The sharp flash that commes with the ADS8260 board is not.

Hi Tore,
Thanks for replying.
I am using Intel StrataFlash Memory (28F2563) and I have checked in
the data sheet it is CFI compliant.
So the problem lies somewhere else.

Check if flash-relative buswidth and interleave has been configured
within CONFIG_MTD_CFI_GEOMETRY.
