Multi-Core Support

Before proceeding with this article, please check out the generic article regarding Multi-Core debugging here. The DA1470 device include a Cortex-M33 and Cortex-M0. The debug related multi-core behavior of the J-Link is described for each core:



  • J-Link performs a default Cortex-M33 init sequence. No special handling is necessary.


  • The devices uses normal Cortex-M reset, no special handling necessary, like described here.


J-Link does not support Cortex-M0.
