I am still doing some testing and just added a fix today so that if a flash chip that supports both 8 and 16-bits is on an 8-bit bus the interface is set to 8-bits. I'll try and get patches out next week.
So far it's working fairly well on all of our boards, most of which have an 8- bit bus but one has a 16-bit bus. I had to change all of the defined addresses for AMD parts and calculate the 16 and 32-bit addresses by applying a mask. The CFI code *should* work if there's an 8-bit part on a 16-bit bus, but it probably will not support two 8-bit parts in parallel. That should be doable with some work. -Aaron On Thursday, March 24, 2011 09:59:07 AM Rogan Dawes wrote: > On 2011/03/24 5:07 AM, Aaron Williams wrote: > > I have it working on our 8-bit boards properly now, though I've only done > > some limited testing. > > > > I basically put in the correct addresses into cfi_flash.h and updated > > various addresses for 8-bit support.
