nrf52832 jlink ob debug on keil and SEGGER Embedded Studio 3.28

[mark]

I use another jlink ob board to connect to nrf52832, and when i use j-link v6.16c，it give a warning prompt "The connected j-link is defective", and i use jlink v5.12f, when i use keil to download hex file to board, and a pop-up dialog box appears "The firmware of the connected J-Link does not support the following memory access:Read @0x02000004 Flags:via AHB-AP"

Hi,

What kind of board is this "another jlink ob board" ? Is it a nRF52-DK ? Please try to update your J-link driver and see if that solves the problem. You can download the latest version here.

EDIT: Solved here.
