Intruction trace with Kinetis KV46

zorrotz — Fri, 19 Oct 2018 07:36:44 GMT

Is it possible to use Intruction Trace funtionallity of MCUXpresso IDE version 10.2.1 with Kinetis KV46 and Multilink Universal FX debug probe?

When I launch Intruction Trace "target not supported" error is generated. I have tried deleting the launch configuration, but it doesn´t work.

Hello Pablo Igor Vicente,

It seems the Instruction Trace function on MCUXpreso IDE doesn't support KV series,

only support KL and K series.

While I will configure it with development .

Have a great day,
TIC

Unfortunately the KV46 silicon does not appear to implement the Coresight Embedded Trace Buffer (ETB) that MCUXpresso IDE requires to provide instruction trace capability.

For comparison here is the list of "Coresight" debug components detected with Kinetis K64 (as displayed by a LinkServer debug connection):

Content of CoreSight Debug ROM(s):
RBASE E00FF000: CID B105100D PID 04000BB4C4 ROM (type 0x1)
ROM 1 E000E000: CID B105E00D PID 04000BB00C Gen SCS (type 0x0)
ROM 1 E0001000: CID B105E00D PID 04003BB002 Gen DWT (type 0x0)
ROM 1 E0002000: CID B105E00D PID 04002BB003 Gen FPB (type 0x0)
ROM 1 E0000000: CID B105E00D PID 04003BB001 Gen ITM (type 0x0)
ROM 1 E0040000: CID B105900D PID 04000BB9A1 CSt TPIU type 0x11 Trace Sink - TPIU
ROM 1 E0041000: CID B105900D PID 04000BB925 CSt ETM type 0x13 Trace Source - Core
ROM 1 E0042000: CID B105900D PID 04003BB907 CSt ETB type 0x21 Trace Sink - ETB
ROM 1 E0043000: CID B105900D PID 04001BB908 CSt CSTF type 0x12 Trace Link - Trace funnel/router

vs the more limited Coresight capabilities implemented on KV46:

Content of CoreSight Debug ROM(s):
RBASE E00FF000: CID B105100D PID 04000BB4C4 ROM (type 0x1)
ROM 1 E000E000: CID B105E00D PID 04000BB00C Gen SCS (type 0x0)
ROM 1 E0001000: CID B105E00D PID 04003BB002 Gen DWT (type 0x0)
ROM 1 E0002000: CID B105E00D PID 04002BB003 Gen FPB (type 0x0)
ROM 1 E0000000: CID B105E00D PID 04003BB001 Gen ITM (type 0x0)
ROM 1 E0040000: CID B105900D PID 04000BB9A1 CSt TPIU type 0x11 Trace Sink - TPIU

Note the lack of ETB (along with the lack of ETM / Embedded Trace Macrocell which generates the tracedata to be collected by the ETB).

Regards,

Thank you.

I haven´t seen that is only available in K series.
