Cortex Debug + ETM Interface

The Cortex Debug interface connector provides JTAG and SWD debugging and emulator support for the Freescale Kinetis K60N512 Cortex-M4 device. This interface allows application debugging and programming of on-chip and off-chip Flash devices.

Serial Wire JTAG is capable of Serial Wire Output for target debugging in addition to allowing application programming and debugging of on-chip and off-chip Flash devices as in standard JTAG.

The Cortex Debug connector also provides instruction-level trace (ETM) debugging support for the Kinetis device at the Cortex Debug connector.


The 20-pin Cortex Debug header (Samtec FTSH-110-01) works with the Keil ULINK2 and ULINKpro and many third party tool vendors.


  • ULINK2 users will need a 10-pin to 20-pin cable not shipped with older ULINK2 adapters. Those users should contact Keil Sales for help in acquiring this cable.
  • When using ULINK2 or ULINKpro, make sure the jumpers at location J10 and J12 are removed.
  • The ULINK2 adapter does not support ETM trace.
