G531H connect to Easy JTAG - GSM-Forum

Hi,
I'm sorry but i'm newbie and i need to know how i can connect it?
I saw the picture where CLK CMD DAT0.
But my questions is if GND on PCB = GND on JTAG and Cable
But
CLK=?
CMD=?
DAT0=?
My cable named with :
N.G=?
TDI=?
TRST=?
SRST=?
TD0=?
TMS=?
TGK=?
NC=?

So what CLK,CMD and DAT0 equals to this table?

is it TDI=CLK?
or what?
Please forgive me newbie.
Another question in the PCB z3x has a picture of eMMc removed from PCB and the pinout on PCB so i have to desolder the eMMc in order to connect it or what?
Or i can solder the wires while the eMMc in on board?
Here is a picture:

PLEASE FORGIVE MY ARROGANT AGAIN.
THANK YOU.

that cable is not for direct emmc connection, that is for old jtag method.

2 different methode . jtag metode and direct emmc metode . cable is different you must buy new cable to do direct emmc

Hi
Cable is fine and you can use for direct eMMC
So,
From right side:
Brown is CMD
Orange is CLK
Green is Dat0
From left side first Black wires is GND
number of CMD is 1 and CLK is Number 3 also Dat0 is Number 5 for VCC and VCCQ you can use any wires between (7,9,11,13,15,17,19 )

I Hope i explain clear...
