I want to try https://www.youtube.com/watch?v=Q5GIZUsXb3I, but cannot see clearly how the J-Link is connected to QuickFeather 1.2 ?
Can anybody please help to show the connection of each pin?
Thank you ...
Bricked but how to connect J-Link?

Connect J-Link to QuickFeather 1.2:
JTAG Interface: The J-Link debugger typically connects to the QuickFeather 1.2 board via its JTAG interface. The JTAG pins on the QuickFeather 1.2 are usually labeled as TCK (Test Clock), TMS (Test Mode Select), TDI (Test Data In), and TDO (Test Data Out).
Ground Connection: Connect the ground (GND) pin from the J-Link debugger to any ground pin available on the QuickFeather 1.2 board to establish a common ground connection.
VCC Connection (Optional): Some debuggers might require a VCC connection. If needed, connect the VCC pin from the J-Link debugger to an appropriate power source on the QuickFeather 1.2 board.snow rider
Pin Mapping:
You need to ensure that the JTAG pins from the J-Link debugger are connected to the corresponding JTAG pins on the QuickFeather 1.2 board. The pin mapping information should be available in the documentation or datasheet of both the J-Link debugger and the QuickFeather 1.2 board. Ensure that you connect TCK to TCK, TMS to TMS, TDI to TDI, and TDO to TDO.

To connect the J-Link to the QuickFeather 1.2, you will typically need to follow the pinout provided in the QuickFeather documentation.
VCC (3.3V)
GND
SWDIO
SWCLK
RESET
Make sure to match the J-Link pins to the corresponding pins on the QuickFeather board. For detailed visuals and step-by-step instructions.

I also encountered the same case. I hope there is some expert who can help us connect each leg.
