That is implemented in the 2.6 kernels. Are you sugesting a merge with
2.6 code? Or there is a patch that implements that in 2.4 kernels?

You probably need buffer writes enabled.

Look around, I've used buffered writes on a 2.4.25 kernel...

Hello all!

	I'm using a linux-2.4.31 based kernel in our board and we are using a AM29LV040B flash device. Our problem is that flash programming is a rather slow process. The responsible is the file cfi_cmdset_0002.c. Is there any patch that fixes this problem and enables fast programming mode?



Thanks for reading (and many more if you reply),
Filipe França.
