Hi TI:
Our customers need to expand the size of EXT_DATA when developing DSP applications.
But after the expansion, it was found that only a part of DSP application was started.
The log of the original normal startup is as follows：
The logs that cannot be started normally after expanding memory are as follows：

Memory expanded from 7M to 8M. The modification method is as follows：
The processor we use is am5718
Linux is running on A15
Linux SDK version 03.01.00.06
RTOS version 03.01.00.06
Do you have any suggestions
