hi now the chip I am using is tms320c6201 ,the reset mode is to boot from external flash memory and the memory map is selected for map1. when initialized sections are burned to flash memory, the flash memory distribution is as follows : the .vec and .text sections are located in the first 64k and the .vec is at the 0x1400000. the .cinit and .data sections' location begins with 0x1410000. as described above, when power is on, the first 64k in the flash memory is automately copied into interal program memory( that is to say: 0 address), after that, program begins to execute some initialization,the .cinit section is copied into the .bss section, finally, main program begins to run. something I don't understand is that when the .data section is copied to interal data memory and how can i do this? otherwise, from the work I have finished, I find that the main progam can still work normally even if I don't consider the .data section. why is so? please help me. thank you very much! |

hi, "The assembler creates the default sections .text, .bss, and .data.The C/C++ compiler, however, does not use the .data section."
