"Embedded" Linux computers (continued again)

For those of you with the Rock 2, you might want the below pin mappings.  The Radxa folks were kind enough to send me the mappings that I was looking for.  I have not fully tested them all but I have tested the ones that are the same as the original Rock and they work great!  So at this point, it's a shootout between the Odroid and the Rock2.  Let the testing begin.  They are both functioning as they should with no issues whatsoever.  (Note that I have not used I2C or serial yet on either of them) GPIO0_A0 = 0GPIO0_A1...

We have the Odroid in hand and it's working great.  I was able to get my whole software stack running on it, which is really great. In the mean time I've been conversing with the Radxa folks on the rock2 square and was able to get the GPIO sort of working.  Currently it's using the sysfs system in Linux, which is pretty standard.  The issue now is that I don't have a mapping for GPIO numbers to actual pins.  If anybody has this information, please let me know where to find it as it would be nice to get the rock2...

Based on my research I had chosen the Radxa Rock 2 as the brains for the Singularity Robot (that I posted a while back).  Now that I have been working with the Rock 2 for a while I've realized some harsh realities.  It appears that Linux isn't fully supported on the Rock 2 setup.  This includes the GPIO not working along with who knows what else.  A good friend chose to go with the Odroid XU4 and he is having great luck with it.  GPIO and all, sigh.  This is not to say that the Rock 2 is not a...
