MOD54415 eDMA Documentation problem

Post by keckrl »

If anyone is trying to figure out how to use eDMA in the MOD54415 and is confused by documentation that inconsistently specifies both 16 and 64 DMA channels, it is probably because you have revision 4 of the MCF5441x Reference Manual. The eDMA chapter in this revision is wrong. Correct documentation can be found in the revision 3 manual.
You can find it by searching the Freescale forums or try this link:

Note this thread also mentions problems with the DMA timer documentation as well.
It would be nice if Netburner would point this out and include the revision 3 manual in the documentation collection.

Noted and noted, this issue has come up before (on this same forum) and we've discussed including it as you mentioned. We'll review this, and I'll get back to you on this.
