Correct - and everything basically works, just the endianess and timing issues. > >> I have a feeling >> that even with timeout_volatile set to zero >> > Instead of tuning the global cache options, you should just read the > chip's node in the /uncached/ directory. That way, the chip is read *in > any case* (and the cache is updated). Aha - I'd missed that in my first read of all the documentation, I'll try that this evening. If that fixes the timing issue reading VAD from the ds2438 chips then its only the endian bug on the ds2413 to tackle (and I have a PIO.BYTE workaround for that!!)
