Request for Clarification on SWJ-DP Interfaces

jashic khader batcha

Part Number: AWR2944

Hello Team,

Regarding AWR2944, i understand it is a cortex ARM based and it should be also supporting SWD(serial wire Debug).

10 pin Debug interface can be used for both Serial Wire Debug (SWD) or JTAG. A special sequence on the SWDIOTMS pin is used to switch between JTAG-DP and SW-DP.

AWR294x Technical Reference Manual, is not having any technical details about SWJ-DP or SWDIOTMS

Question: please clarify about SWJ-DP and is the interface available in AWR2944to use SWD(serial wire Debug) or any way to switch between SWD and JTAG?

Reference link: https://developer.arm.com/documentation/ddi0314/h/Debug-Access-Port/SWJ-DP?lang=en

Thanks in advance for the reply!!

Regards,

Jashic K

Hi Jashic,

You can refer to Chapter "6.2 Serial Wire and JTAG select mechanism" from "ARM Debug Interface ADIv5.1 Supplement" as mentioned in the reference link share by you.
