Improper Command Sequence

[Fry, Dan]

Hi List,

I'm still trying to get JFFS2 up and running on an atlas demo board. 

I have four 64Mbit Intel Strata Flash chips which are seemly being detected.


physmap flash device: 2000000 at 1c000000 
Physically mapped flash: Found 2 x16 devices at 0x0 in 32-bit mode

Physically mapped flash: Found 2 x16 devices at 0x1000000 in 32-bit mode

JEDEC ID: 89 15

0: offset=0x0,size=0x40000,blocks=64

1: offset=0x1000000,size=0x40000,blocks=64  


However when I attempt to mount /dev/mtdblock0/ as JFFS2 I get the
following: 

JFFS2: Erase block at 0x00000000 is not formatted. It will be erased

JFFS2: Erase block at 0x00040000 is not formatted. It will be erased

JFFS2: Erase block at 0x00080000 is not formatted. It will be erased

JFFS2: Erase block at 0x000c0000 is not formatted. It will be erased

JFFS2: Erase block at 0x00100000 is not formatted. It will be erased

JFFS2: Erase block at 0x00140000 is not formatted. It will be erased

JFFS2: Erase block at 0x00180000 is not formatted. It will be erased

JFFS2: Erase block at 0x001c0000 is not formatted. It will be erased

JFFS2: Erase block at 0x00200000 is not formatted. It will be erased

Questions :
1) Does MTD support Intel Strata Flash??
2) Could there be a locking problem? 
-- I looked through the code and it seems that locking is handled.
