Re: [microblaze-uclinux] problems with flatfs



hi
u can tri in the path as
Kernel config -> mtd support -> mapping chips -> cfi physical memory
map(1st option).
if u select this option then u can change 2 to 4 as i think.
although we have this option disabled.
and no problem in flatfd.

Hello together,

thanks for your hints, but I've got a closer specified problem to solve
now:
when booting, uclinux should print the following lines on minicom:

....
microblaze auto-config flash probe(0x21000000,8388608,2): 800000 at
21000000
 amd/fujitsu extended query table v1.0 at 0x0041
flash: ....
flash: ....
number of cfi chips: 1

what I get instead is:

....
microblaze auto-config flash probe(0x21000000,8388608,4): 800000 at
21000000
cfi: found no flash device at location zero
....

can you tell me where i can change the 'four' at the end of the brackets
to a 'two' ?

thanks,

sigi
