The Quartz64 model A I purchased should be here in a few days. I would like to connect a JTAG/SWD debugger to it.
Where could I find documentation where this is described? In the schematics for the board, I see mention of JTAG in few places, but I am not sure where physically the pins are on the board.
Can anyone provide specifics? Also, aside from the RK3566 datasheet are there any reference manuals/guides for the board? Where can I find these? Also, the same for the Quartz64.
No response from Pine64? I understand the board is not ready for production use, and I am using it only for exploring/experimenting. Surely, a JTAG is present that was used for the UBoot and Linux porting efforts.
An article https://crwulff.blogspot.com/p/rock64.html I came across by a Chris Wulff (thank you Chris), is about JTAG/SWD on Rock64. Apparently the what appear to be two JTAG pins (TCK and TMS), seem to really be SWD pins (SWCLK and SWDIO). Similarly on the Quartz64 schematic I see ARM_JTAG_TCK and ARM_JTAG_SWD.
Is it true that Quartz64 follows the same as for the Rock64? After all Quartz64 is after Rock64/RockPro64.
Could anyone please confirm that indeed the ARM_JTAG labelled pins are actually SWD and not JTAG, and Chris Wulff's article/blog is applicable to Quartz64?
