CCS/AM4379: BiSS-C debug causes CCS crash

Michael Kapuscik
Prodigy 60 points
Part Number: AM4379

Tool/software: Code Composer Studio

I'm trying to setup a BiSS-C implementation from www.ti.com/.../tidep0022 on a IDK437x evaluation board and every time I try to connect to ICSS0_PRU0 while debugging my CCS crashes.

I have been trying to follow the steps listed in tidu794a on pg 34 as close as I can however they seem to be a little out of date and as such I have had to combine my existing GEL files with the BiSS example ones.

The crash seems to happen directly after I run PRU_ICSS_PRCM_Enable and then try to right click on the PRU in the debug view and connect to target.

I created a completely new project as well as a new target configuration and was able to replicate the problem.

I am running CCS 6.1.2 on ubuntu 16.04 64bit.

Any help is appreciated,

-Mike

    Hi Mike
    In part - because this is a small stand alone example there will be some gel differences with the CCS gels in C:\ti\ccsv6\ccs_base\emulation\boards\idk_am437x\gel. Did you encounter a problem with the project gels?

    Did you see the e2e discussion: e2e.ti.com/.../1493629

    As a word of caution - This is a small stand alone example that was developed as a demonstration of the PRU's ability to support the BiSS Protocol. This is not part of an SDK and is not intended to be used for product development. This design is a precursor to a development of a BiSS Master interface that would be part of the PRU-ICSS-INDUSTRIAL-DRIVES package.
