[microblaze-uclinux] Flash memory in microblaze Uclinux



Hi,

I am using uClinux on microblaze, I am trying to add a flash chip
memory to my system to make it portable from everytime downloading
kernel into my system.
From john website, the flash part is still underconstruction, so is
there anyone successfully integrated a flash into your system?

I tried to read some value out from my flash chip, by using "mrd
0xff000000" in XMD (0xff000000 is my flash base address) , there were
FFFFFFFF comming out. is it alright? When I plot a uClinux into my
system, something like this:

MBVanilla flash probe(0xff000000,8388608,4): 800000 at ff000000
CFI: Found no Flash device at location zero

Creating 1 MTD partitions on "RAM":
0x00000000-0x0009b000 : "Romfs"

does it mean, found flash or not??
how can I check the flash chip avaliability under uClinux??

thx
SKY
