Hi all,
I'm sorry, I sent to the list the debug messages of a older U-Boot version. Here are the debug messages of the current U-Boot version.

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.
