JTAG interface? - duane - 12-20-2015 I am not asking for a connector (that would cost money) what I am asking for is this:
Will this be available? NOTE: I also see there are two JTAG-SEL pins, These need to be "modifiable" by some means. Option 1: A sufficient solution would be trace on the PCB that can be cut with a razor knife (this would be zero cost) please make these large enough that a human can actually do this. Option 2: Would be to use some zero-ohm components that can be removed or changed Also will need documentation about what these pins do, etc - they are not well documented in the existing PDFs on the Pine64 web site (the documents say the pins exist, but do not say what the pins do) -Duane.

Unfortunately we didn't bring out the solder pad. If you interest to dig further, there is Allwinner SoC data sheet on the Pine64 wiki page (http://wiki.pine64.org). RE: JTAG interface? - duane - 12-30-2015 Solder pads, or holes should be a priority future pcb revisions or spins. Reason: Many developers have access to arm64 jtag tools, your bring up process will be much faster and go further if this was available. -Duane.

I know boards have reached people already. Do you know what happened with this idea? Are there any JTAG pads on the final board?
