Part Number: TMS320F28069M
Other Parts Discussed in Thread: TMS320F28069, LAUNCHXL-F28069M
Hi,
We are working on TMS320F28069 microcontroller and using LAUNCHXL-F28069M launchpad.
We are using the SYS/BIOS [6.83.0.15] as the platform. Below are the details of tasks and ISRs
Task_1 - stack size = 512
Task_2 - stack size = 512
Idle Task - stack size = 256
System (HWi and SWi) Stack size = 1024
Heap size = 2048
Total ISRs - 6
Recently USB peripheral library (usb serial device) is integrated into the existing project. After that the task abort is happening.

Actually stack overflow is happening.
Increased the System Stack size, Total heap size, Task_1 and Task_2 stack sizes. But the issue is not resolved. Abort was happening again.
But when the Idle task's stack size is increased to 512 keeping all the other values (System Stack size, Total heap size, Task_1 and Task_2 stack) unchanged, abort is not happening.
Why the abort is not happening when the Idle task's stack is increase?
Regards,
Shijo Thomas
