You using M29W320DB (bottom boot) chip right?
Yes
What is the flash configuration that you are using with BDI2000? Can you paste that part of BDI config file?
WM32 0x80000004 0x0000FFC0 ;CS0 start = 0xFFC000000 WM32 0x80000008 0x0000FFFF ;CS0 stop = 0xFFFFFFFF WM32 0x80000300 0x00047800 ;BOOT ctrl
Are you using the CFI driver from top of the tree?
No, I've done the porting for my board with the 1.1.4 version. I'll try to do the porting to the top of the tree.
If not can you please use the one from top of tree? Also it would be great if you provided "flinfo" command output as well.
What exactly was your command?
mmh 0xffc000aa 0x9800
or
mmb 0xffc000aa 0x98
The output it's the same for both commands,
This output is looking like for x16 but byte reversed. Is it possible that hardware designer reversed the data bus? If not your CS programming/logic for the flash might not be correct... Also check BYTE pin of your flash parts. For x8 mode it should be pulled low.
But, U-Boot is running properly from this flash. If the hardware was wrong could be it possible? We have another board with the same schematics mounted with a spansion flash and we haven't got any problem. Could be a bug in the mounting process or is it a different behaviour of the flash accesing the CFI ?
