DSP has a problem with printf function running away in CCS environment [Copy link]

When I used the simulator to connect to DSP C5509A in CCS environment to debug an RTC program, I found that the output window did not output time information regularly. I thought it was a problem with the interrupt vector setting at first. After single-step debugging, I found that the program ran away in the printf function. I was puzzled. After searching, it said that the heap and stack were not set, but they were already set in the CMD file. Later, I found that it was a problem with the compilation and connection command settings. The heap size and stack size were only allocated 500. I deleted 500 and CSS automatically allocated or set them to twice. It was done~~~

The settings are as follows: Project->Build Options->Linker->Basic under stack size and heap size
