After a check after Nguyen Hoan Hoang remark.

"if jlink senses 0V, probably you have a bad connection. Verify that you actually have 3.3v on the pin target of jlink"

i finally find my mistake, I swapped the pinout row, i came into that conclusion by measuring a negative voltage in pin19 of jlink while performing the command: power on !

it's power up as i mentioned on my question using this pinout: PTR5518 pin 9 and JLINK pin 4 to ground. PTR5518 pin 10 and JLINK pin 1 to Vcc (3.3 Vi used an arduino as external power) PTR5518 pin 4 to JLINK pin 7 (SWDIO). PTR5518 pin 5 to JLINK pin 9 (SWCLK).

For low cost debug jtag that can also be used for mass production, have a look here.

That is probably because your board is not powered up. VTarget should be connected to your board's power source. It does not provide power to your board. It requires power from your board.

OK for mass production, i'm not yet ready for that, i just want to program my module. why it gives me VTarget = 0.000V ?

May be, the EDU license only allows for education and personal hobby use. It does not allow commercial or mass production use. You are infringing the Segger license.
