Does the JLink Pro POE require an adapter to connect to an ARM Cortex Debug connector?

------Question for 8.12.28 Please Put your question below------

There are two pinouts for 20-pin connectors for ARM programming. My target device says that it supports J-Link, but it uses the Cortex Debug 20-pin connector, which is different from the published J-Link pinout. Does the JLink Pro POE include the required adapter?

Hello @karl.papadantonakis

The J-link Pro PoE kit does not come with an adapter, it comes with a J-link Pro PoE, a 20-pin ribbon cable, and a USB cable.

Hi karl.papadantonakis,

I believe @anthony_14117 correctly shows what comes with the J-Link Pro PoE kit, part number 8.12.28.

If you intend to use the J-Link Pro PoE debug probe to program/debug the EFM32PG23 Gecko present on the PG23-PK2504A development board rather than use the J-Link debugger integrated onto that dev board, then you will need the 8.06.00 J-Link 19-pin Cortex-M adapter cable.

@David_1528 Yes, I was thinking of using a J-Link Pro PoE to program the MCU on the EFM32PG23 (aka PG23 Pro Kit). The 8.06.00 adapter looks like exactly what I need for this, and confirms that the connectors are indeed different. Thank you!
