I believe the 88F5182 has CESA as well, although as far I can see the main difference is that while the 88F6xxx (and MV-78xxx) CESA has an associated (to some extent can be considered as dedicated) TDMA engine, the one in 88F5182 does not, and can only use the generic purpose engine (IDMA). Our driver assumes TDMA and was only tested with 88F6xxx and 78xxx, so it seems there's some work involved with getting this to work on the 5182. Let me carve the code out for your reference so that you can try to extend it to work wirh Orion. >> BTW: out of curiousity, what is the platform based on 88F5281 you're using? > It's a TS-7800: > http://www.embeddedarm.com/products/board-detail.php?product=TS-7800 Does the generic DB-88F5XXX kernel config and existing code work with this device, or have you had to modify anything?
