CCS 6.1 with BeagleBone Black and PRU

Were there any other messages in the console window at the time you got that error? Could you please post the build console text verbatim?

Are you using the option --disable_auto_rts?

I did not change any settings, so they should be the defaults.

I suspect that, when you first set up your CCS project, you didn't realize you told CCS you are using the Cortex-A8 core on the AM335x device of the BeagleBone Black.  When you go through the project creation dialog, it defaults to the Cortex-A8 core unless you indicate otherwise.  The PDF attached below is one slide from a larger presentation about a PRU workshop.  This slide shows you to set up the PRU project in that workshop.  Your project setup will be very similar.

Thanks and regards,

I didn't create the project, I'm using the source files from here: processors.wiki.ti.com/.../PRU_Cape:_Building_Demos

I installed everything on a different computer and it gives me the same error.

Thanks
