Re: [U-Boot-Users] Flash Programming Time
What exactly do you mean by "standard algorithms" - that would be the CFI driver. Are you really using this? Did you set CFG_FLASH_USE_BUFFER_WRITE in your board config file?
Best regards,

Hello Wolfgang, i basically use the at91rm9200dk configuration but adjusted for larger Flash size. I think too it's the CFI driver which is used. The definition of CFG_FLASH_USE_BUFFER_WRITE in this configuration file has no influence to programming time. Can you tell me where i have to change to implement the "buffered write" ?

No, it ain't.

The at91rm9200dk configuration uses it's own driver, which does not handle this.

Change the code to use the CFI driver.
