- The link to "FPGA Core Creation Guidelines" appears to be broken in the Wiki - can anyone point me to the relevant information?
Hi
Wat are recomended type of male headers mating with the Industrial IO Development Kit expansion IO connectors J700-J702.

This seems to be a problem with the latests Angstrom repos. I was able to find a forum post related to this. https://groups.google.com/forum/#!topic/beagleboard/bsiWha74mc8

Has anyone had any luck getting "missing" Angstrom packages installed when using the 2012-08-10 MDK? The two examples I've been looking for are sudo and ntp:

I just followed the [[DSP_Hello_World]] tutorial and didn't have the same build errors you did. It should be noted though that the example files in the latest MDK were not updated and would exhibit these errors you mentioned.... - MW 11:12 AM Software Development: RE: Data Transfer over DSPLink

- Keep in mind that the OMAP-L138 also has built in pull-up and pull-down resistors on just about every pin.
On reset, IIRC, most of the pins have weak pull-ups enabled. Search for the PUPEN register in the TRM and check the state. Un... - CR 12:02 PM Software Development: RE: GPIO Output immediately after power on

there are 2 possibilities for where pins are being enabled and potentially toggled. A lot of this depends on which pins you are talking about too.
