Guys,

I tried to connect J-link to my STM32 board,
Does anyone know why J-Link can not recognized my board ?

Which jumper setting should I consider well ?

can I use JTAG for power supply on Pin 19 ?

is it possible if my chip (STM32 chip) burned ? overheat from my solder ? or just VDDA issue ?
 

Why not use the SWD interface
Very simple

 

Thank you guys, it's working now...I tested for the code....no problem
