How to connect ULINK to Colibri iMX7. I did not find a description of six test points on the Colibri module (TDO, TCK, TDI, TMS, TRST, MOD, GND?). Can you tell me how to connect Colibri with ULINKpro D (pin-to-pin)?
Thanks.

The JTAG interface is located on test points on the underside of the module. You should use Colibri Evaluation Board to access it. And keep jumper JP29 in position 2-3. Find more information here.
I need to solder JTag connector directly on Colibri module. I want to debug M4 core on my device. I need to know, what are pin numbers. For example a = pin 1 JTAG TDI, b = pin 2 JTAG TDO,… And I also need to know where on module I can solder wire for signal JTAG SYSRESET, VREF and GND. Can you tag them in the photo of the module?

May I know which Carrier board you are using ?
I’m afraid you will void the warranty by doing that.
JTAG pogo pin header pin-out information is as follows.
1 | e | TDI
2 | d | TDO
3 | a | TCK
4 | b | TRST#
5 | c | TMS
6 | f | NC
Can you tag in the photo of the module where should I connect VREF (+3,3V) and GND for JTAG? If I get it right from Evaluation Board layout I don’t need any JTAG SYSRESET signal for JTAG on iMX7 because it is not needed.
I am using Carrier Board Iris. Thanks to the Evaluation Board photo I know now which test pin is which. 
I count on forfeiting the guarantee.
True table is (PCBs are attached to each other. One PCB must turn mirror.):
1 | e | TDI
2 | d | TDO
3 | a | TCK
4 | b | TRST#
5 | c | TMS
6 | f | NC
Can you tag in the photo of the module where should I connect VREF (+3,3V) and GND for JTAG?
You can take any 3v3 available on Iris Board as VREF. Refer Iris schemacits for 3v3 and GND availablity on headers.

My bad, you are correct, it is mirrored wrt to your naming on module. I too updated my table.
