Buy ST Link programmer for STM32WL5JC

Which ST Link programmer is best for STM32WL5JC (Lora MCU) for advanced debug facility (still reading, ??trace, monitor??)

Hello @David_ 

I will recommend you to use the STLINK-V3SET. But you still can use other STLINKs (just make sure you are using an original one and not a clone (specially for the STLINK-V2)).

Best Regards.

Many thanks.  I read UM2448 Rev 8, page 24/51.  Is it correct that I should connect

SWDIO (of STLINK_V3SET) to PA13 (of STM32WL5JC),

SWCLK (of STLINK_V3SET) to PA14 (of STM32WL5JC),

NRST (of STLINK_V3SET) to NRST (of STM32WL5JC),

GND (of STLINK_V3SET) to GND (of STM32WL5JC)

Pin 1 of STLINK_V3SET is stated as INPUT.  Is that used by STLINK_V3SET to sense the supply voltage of the target board?  I should connect Pin 1 of STLINK_V3SET to the 3.3 volts supply line of the target board, right?

The STM32WL5JC does NOT has a pin named SWO.  Hence, Serial Wire Viewer (SWV) trace function is NOT available for the STM32WL5JC, right?

TIA

PB3 = JTDO / TRACE SWO
