AM5726: DSP intermitted build errors for IPC program

Jon Lake

Part Number: AM5726

Hi,

I'm working on a program on the DSP2 core of the AM572x that uses the IPC packages from TI. I based the project off of the IPC examples provided in the SDK. The build occasionally fails, even when nothing has changed in the files or projects and it seems to be related to an overlap in definitions in the ipc directory and the utils directory. It doesn't fail every time, which had me thinking that maybe having a multithreaded build was occasionally building in an incorrect order, but I disabled multithreaded builds and I'm still seeing the problem.

Here is the build output I'm seeing:

Hello Jon,

Can you share more details about your environment? What SDK/s are you using and what version?

Best,

-Josue

Hi Josue,

I'm using components from the 06.03.00.106 SDK, with IPC 3.50.04.08 and CCS 9.3.0.00012. Here's the full list in my TI directory:

I'm also compiling headless on Windows with the command "C:/ti/ccs930/ccs/eclipse/eclipsec.exe -noSplash -data ./src_root -application com.ti.ccsstudio.apps.buildProject -ccs.autoImport -ccsbuildType full -ccs.configuration Debug -ccs.projects Xray_DSP, IOScannerDSP2".

I'm not sure if compiling multiple projects that are both IPC programs affects anything.

Thanks,

-Jon
