HW: wire mods required to enable JTAG
Created by: jadonk
Confirmed feedback on the board's JTAG:
I finally manage how to use the Allegro Board Viewer.
It’s confirmed that the JTAG pins are shorted together. I’m not sure if they even connected to the SOC.
It looks like R199 and R200 are just connected together in this photo above. SOC -> R200 -> R199 -> SOC ( the red trace that has the letter JTAG_RTCK on it)
And the pins 9-11 on the JTAG connectors are directly connected to each other
So we can cut this trace, and the trace between R199 and R200, then blue wires to the R200 and R199. We only have to do 1 blue wire.
That will probably fixe it :-)
