One minor comments regadring the Dragonboard Documentation referenced by Steve in his above e-mail:,
I just read the text from the Dragonboard:
On page 13 of the DragonBoard Hardware Manual: “APQ8016 SoC JTAG interface is routed to J15. If the use of JTAG is required, J8 need to be soldered to the board. The connections and connector pitch meets the 96Boards specification for the JTAG interface.”
and I think there is a minor error in the following statement: … J8 need to be soldered to the board…
Since J8 in Section 1.1 Board Overview is the Low Speed Expansion Connnector
So the Dragonboard Docu should say … J15 need to be soldered to the board … ?
In addition looking at J15 on my Dragonboard it looks that one needs a 2x10 Header like the FTSH-110-01-L-DV, versus the 2x5 Header FTSH-105-01-L-DV mentioned in the Hikey Docu. I nealry overlooked this.
