Hi Community ,
Im working on the debugger ofLPC55S69 ,trying to use the microcontroller and program it with external Debugger .
Board :LPC55S69
Debugging using SWD.
PROBLEM:
Thank and Regards

Hello @ujwal_kumar_N_L ,
1. If you mean with 'dump the code to the microcontroller' the programming and flashing of it, then yes: you can use SWD for this. You don't have to use a J-Link, you can use any other debug probe supporting the LPC55S69, e.g. MCU-Link (Pro) or P&E Multilink.
2. You need SWCKL, SWDIO and GND. SWO is a trace pin, see https://mcuoneclipse.com/2021/05/22/swo-with-arm-cortex-m33/
3. Use a J-Link, or program the J-Link firmware on the board. Or use the NXP MCU-Link Pro or non-pro, or use a P&E Multilink. Choice depends on your needs and budget available.
