For ST40 targets you need to read carefully how to connect the JTAG port. The TRST pin is not the regular TRST pin on pin 1 of JTAG.
The start sequence of TRST is very important to allow it enter TRAP ON mode.

Not able to download the file. Just attach in here or send email. Do you ever get TRAP ON? If not it will not work.

NT pin 1 will not work. You also can try different timing on power on. SV8000HD is using ST7100 and it works. Your must not be SV8000HD so XML tweaks might be needed.

You seem to have many targets that is not listed in the xmls. If you cannot make them work you need to consider donate the devices. However I saw you keep quite after a while. ST7100 is ST40 core and you posted in ST20 forum.
