BeagleBone Black SRM released from asciidoc version on wiki

I’ve updated https://github.com/beagleboard/beaglebone-black/blob/master/BBB_SRM.pdf such that we can use it as a template for future SRMs as well as to accept community edits.

Source is at https://github.com/beagleboard/beaglebone-black/wiki/System-Reference-Manual in asciidoc format. PDF conversion done with asciidoctor-pdf. Looking to move to asciidoctor.js in the future.

Wow, what board is your hand model holding ? Can’t tell. Every time I look at the opening picture. My eye goes straight to those bright red fingernails . . . Just sayin`

Looks like a much out-of-date BBB rev A5, based upon the stickers...

  Wonder what the model's nails look like after all these years with a
rev C BBB <G>
