Dear Brendan,

Another question : I am looking at a Spansion CFI flash

http://spansion.com/products/support/datas...-p_00_a11_e.pdf (http://spansion.com/products/support/datasheets/s29gl-p_00_a11_e.pdf)

1. It allows for both regular read operations and page read operations (page read operations are much faster !). Using the CFI controller and IDE HAL is there some way to switch to page read operations to speed up the read access to this flash ?

2. For booting from this flash - can the standard CFI boot loader be used (and thus all I have to do is connect up the flash signals and set the correct reset address and then carry out a reset and the boot process will be automatic (assuming that I have set the correct execution adress from which the code is to be run !))?
