Subject: [U-Boot] CFI Flash write speed
Date: Thu, 13 Aug 2009 13:51:00 +0200	[thread overview]
Message-ID: <006201ca1c0c$55a62ea0$00f28be0$@de> (raw)

Hello Mr. Denk,

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?

Thanks,
Andreas
