stm32l432kc dev board debug interface?

[OCosk]

I have a STM32L432KC board purchased by a colleague. I installed STLink device drivers according to sheet and try to set it up. However, it never gets recognized as a STLink device (neither on Windows 7 nor on Mac OS Majove) but rather as a J-Link device when I power it on via USB and the jumper is off. Does any idea why is it that? Production error or am I missing something ? (Note: stm directly connected to laptop without any other peripherial)

Segger provided a firmware to create a J-Link OB, this was likely applied.

See Chapter 3 https://www.segger.com/downloads/application-notes/AN00021

Use it as a J-Link, or convert back
