[U-Boot-Users] Re: problems with the strataflash driver in U-boot

[Josh Fryman]

no dice.  here's the configuration in chip terms, followed by my config
settings, followed by the driver ouput.  

suggestions?

-josh

two banks.  each bank is 32bit data, 32MB in size, made up of 2 chips in
parallel.  each chip is 16MB x 16bit data, organized as (128) 128KB 
sectors.

wiring:   0-32MB = 2x Intel 28F128J3A-150

          address space 0x0000 0000 - 0200 0000

               Shared:  Flash A0     = Gnd
                        Flash A1:A23 = PXA A2:24
                        Flash CE     = PXA FlashBank 0 CE

               Separate:  Chip A:  D00:15 = PXA D00:15
                          Chip B:  D16:31 = PXA D16:31 

          address space 0x0200 0000 - 0400 0000

               Shared:  Flash A0     = Gnd
                        Flash A1:A23 = PXA A2:24
                        Flash CE     = PXA FlashBank 1 CE

               Separate:  Chip A:  D00:15 = PXA D00:15
                          Chip B:  D16:31 = PXA D16:31
