CCS/CC1310: Crash attempting to access AUX_AIODIO0 from scifInit in code generated by Sensor Controller Studio

Chert Vindle

Part Number: CC1310

Tool/software: Code Composer Studio

I used Sensor Controller Studio to setup a UART emulator to get a 2nd UART on this part. I selected no OS for the project. I imported the code into my Contiki-NG based project as best I could understand from the html file generated by Sensor Controller Studio. Now, when trying to use the code generated, I get a crash in scifInit(). It appears that the code is trying to access location 0x400C1004 AUX_AIODIO0), but when I view that location in the debugger it shows up as all ???? So, it appears that that memory location is not enabled and I'm not sure why or what that means.

Chert,

If you are implementing it to a TI-RTOS application, set the Operating System to TI-RTOS.

I am not using Ti-rtos. As indicated, I am using Contiki-NG.

Here are some screenshots showing how the code is about to try and read from location 0x400C1004, but the debugger seems to show that region of memory is unaccessible. I don't understand why.

Chert,

Thank you for providing these screenshots to work with. We're still looking into this and will get back to you shortly.

Hi Chert,

Sensor Controller support for Contiki-NG is not fully developed. I know for sure we haven't tested it, but it could very well be that it "just" works with the current version of Contiki-NG. Just make sure that you use the SimpleLink platform on Contiki-NG.

Either way, you need to set OS to "TI Driver Porting Layer" in your SC project, since Contiki-NG uses NoRTOS (not TI-RTOS).

I got it working. I am still using the "no OS" option Sensor Controller Studio (changing to TI Driver Porting Layer caused all sorts of compiling issues.) The problem was I wasn't including the call to scifOsalEnableAuxDomainAccess();
