Hi all,

We have a MPC5200B custom board and we are evaluating the Numonyx
M29W128 Flash as a second source for the Spansion's S29GL128.
I've checked the top of the tree version of the U-Boot (u-boot.git) CFI
driver and the Numonyx Flash is not detected. This is the U-Boot debug
output:

This is the debug output for the Spansion Flash that works fine.

So the problem seems to be that the Numonyx Flash do not put the CFI
query information in the odd bytes as you can see here:
	fwc addr fe000000 cmd f0 f0f0 16bit x 8 bit
	fwc addr fe0000aa cmd 98 9898 16bit x 8 bit
	is= cmd 51(Q) addr fe000020 is= 5100 5151


I've checked the U-Boot mainling list and I've found only something
about a M29W128 bug but in a coldfire architecture. So I think the
Numonyx Flash has been tested in some boards but I don't knwon if there
is full support in U-Boot for it. If not, is there a patch available or
in process? Any clue will be welcomed.

TIA,

Hi all,

I'm sorry, I sent to the list the debug messages of a older U-Boot

Hi all,

This is a patch to fix the NUMONYX's M29W128GL cfi detection bug in my
Lite5200B based custom board. I thing I's only a starting point for a
more formal patch valid for any kind of architecture (big and little
endian) and flash layout (I've only check it in a 16x portwitdh 8x
chipwitch).
I'm not a CFI flash expert and any feedback about this issue will be
welcomed.

TIA,

Hi,
Did you manage to solve this problem eventually?

Yes, and I submitted a patch only valid for my board architecture and 
flash layout.
