RTOS/CCSTUDIO-SITARA: HeapBuf alignment parameter in CCS

Dear TI E2E,

I am setting up a HeapBuf instance for AM335x using the SYS/BIOS app.cfg. When using the GUI, I set the alignment=8 (because this is the worst-case structure alignment for ARM devices according to the SYSBIOS User Guide). However, if I look at the cfgScript, the alignment=0. I can manually change the cfgScript heapBuf.align=8, and the GUI also says 8. If I manually change the cfgScript heapBuf.align=0, the GUI says 8.

1. Is this expected behavior?

2. What is correct way to setup the HeapBuf alignment parameter for the AM335x target device?

I would appreciate any additional information. Thank you!
