physmap-flash physmap-flash.0: map_probe failed
uclinux[mtd]: RAM probe address=0x22f808 size=0x41f61000
Creating 1 MTD partitions on "RAM":

mtd: Giving out device 0 to ROMfs

uclinux[mtd]: set ROMfs to be root filesystem
TCP cubic registered

List of all partitions:
1f00 1080708 mtdblock0 (driver?)
No filesystem could mount root, tried:
Kernel panic - not syncing: VFS: Unable to mount root fs on
unknown-block(31,0)
From what i see, since at boot time i am copying image.bin comletely in
ram, and flash cannot be detected from MTD, since i have now enabled RAM
support, MTD now find the romfs on the ram, maybe this can be useful
just to see the next problem.
About the flash detection, ID of the SST Manufacturer is 0xBF, and
should be read at address 0 of the flash (mapped as 0xffc00000),
To read it, the datsheet shows:
Software ID Entry7,8 555H AAH 2AAH 55H 555H 90H
Actually, at reset, colilo run from the flash (on CS0), then, from
colilo i load image.bin into RAM, so i don't see any reason why th probe
fail..
I am going ahead analizing the msg, every idea is appreciated,
Manyt thanks,
Angelo

I have a 16bit word, 4MByte flash, mapped at 0xffc00000.
Do i have to set this address somewhere in the kernel, to allow
mtd to
detect it ?
It would also be useful to know the manufacturer and part # of the chip.
Apologies if this wa mentioned and I missed it.
