J-Link LITE with Cortex-M33

Is it possible to use LITE to debug a Cortex-M33 (specifically Nordic nRF9160/61/51)?

I do not see it listed on https://www.segger.com/products/debug…k-lite-cortex-m (Cortex-M0/M0+/M1/M3/M4/M7 cores supported).

However, Cortex-M33 is listed here https://www.segger.com/products/debug…f-known-devices as "J-Link debug probes" general support, and the particular microcontrollers are listed here https://www.segger.com/supported-devices/nordic-semi/nrf91

I would appreciate any info about someone having tried that.

Hello,

It looks like the website is outdated. Since J-Link LITE V9, debugging Cortex-M33 targets is supported.

For a complete overview of all J-Link models, their features, and supported cores, please refer to the following link:

Thanks for you prompt response, Simon. The info we had found was a bit ambiguous, and now it is all clear.
