Regardless, I might want to beta test it for you -- I have been working with a board that has two different FLASH devices on it. I'll have to give that one a little think. --wpd > -----Original Message----- > From: Andrew Lunn [mailto:andrew@lunn.ch] > Sent: Wednesday, August 04, 2004 3:14 PM > To: eCos Disuss > Subject: Re: [ECOS] Flash infrastructure rework > > > > However in the background i took a step back and overhauled > the whole > > flash infrastructure in what i hope is a clean and > consistent API with > > all the features required: > > > > Multiple device drivers at the same time > > Multiple instantiations of the same driver > > Probing to detect what is actually on the board > > Support for boot block devices which have different > size blocks > > Thread safe when used with the kernel > > Does not pollute the name space > > Optional backward compatible with old drivers > > Optional backward compatible with old API > > Able to support multiple JFFS2 filesystems > > Redboot to be able to access multiple devices > > Documentation! > > This is about ready to go live.
