Developing environment is: CCS ver  5.4.0.00091; MCSDK Packages: 3_00_01_12

Bootmode:  ARM SPI Little Endian mode.

I have observed the below errors thrown by ARM while executing our application code on DSP.

Could you please provide the reason for this behavior ? How to avoid it ?

Thanks in advance.
