Hello expert,
I am asking this question for our customer.
The customer uses TMS320f28377S, the CCS version and the compiler version are shown in the figure below.
Customer find that when the uninitialized data is allocated, if the addresses assigned by .ebss, .esystem, .cio and .data contain addresses after 0x10000, the program cannot run, and the following figure will be displayed after debugging.
For example, in the following figure, .ebss, .esystem, .cio, and .data are allocated to addresses before 0x10000, which can be debugged normally.
For example, if .ebss, .esystem, .cio, and .data in the figure below are allocated to addresses after 0x10000, the problem mentioned above will occur.
Since I don't have the EVM of the F28277S, I used the F28379D for testing, and I can't reproduce the customer's problem. I noticed that CIO is displayed in the upper left corner of the console table. Is it a problem of .cio allocation? Could you please kindly help me analyze it? I'm attaching the customer's .cmd file below
