Hello, I have tried a few implementations, with the number of samples: 30,000 --> 300,000 --> 600,000. I had no issues with 30,000 or 300,000, as far as I can tell. I haven't made any changes to extram_pool_sz, and don't actually know where the default for this is set. If you could please

[beagleboard] Update: libpruio (fast and easy D/A - I/O) - version 0.6.4b

In version 0.6.4 some speed optimizations in the ARM code are done. This may lead to race conditions between ARM and PRU in sequences of fast ???->setValue() function calls. The bug is fixed in version 0.6.4b, which I uploaded today. Also the re-muxing in the DTOR is fine again. Regards --

[beagleboard] bone kernel questions.....

Couple of questions regarding the bone kernels 1) Is there a reason update_kernel doesn't install the various "extras" for the bone kernel like it does for the ti kernels? I don't really care as I don't need them, but it kind of surprised me that libpruio and such were not installed.

[beagleboard] Can't get Dallas 1wire to present a device

Hi! I'm trying to forward port some stuff to latest uboot and kernel. Part of it relies on Dallas 1Wire. But I can't seem to get devices to appear on the bus. Here's what I've done # Ensure have the latest overlays $ git clone https://github.com/BeagleBoard/bb.org-overlays.git $ cd bb.overlays
