Dear "A. Geisreiter",
In message 006201ca1c0c$55a62ea0$00f28be0$@de you wrote:
CFG_FLASH_USE_BUFFER_WRITE is already defined in the project-header file. I have configured the CPU registers for access the flash memory with maximum speed. But I think it is although very slow. If I use Windows CE to copy something to the flash memory I have transfer rates of 140kB/s. With U-Boot I have only 75kB/s. What else can I do to increase the transfer rate?
I guess the PXA270 suffers like all (?) ARM from the fact that data cache is not effective. Jean-Christophe has been promising for some time to submit patches that are supposed to fix this.
I have no idea though when these might hit mainline.
Best regards,
Wolfgang Denk

Hello! I'm from outer space, and I've made myself look like a signa-

know it feels good to you, because you're smiling. I'm very horny, so
