Hello.
I need to debug crazyflie 2.0 via JTAG. For this i connect JLink to debug adapter kit ( in 20 pin jack ) and connect debug adapter kit to crazyflie 2.0 via 6 pin jack. JLink can't detect quadcopter's chip. What I need to solder to connect quadcopter's chip with JLink via debug adapter kit?
Thank you.

Hi, no there is nothing to solder.
Make sure the addapter board jumper is set to NRST and that JLink is well configured for SWD. That is how I can connect it:
Code: Select all
$ JLinkExe -if swd
