TMS320F28335: F28335 cmd

Part Number: TMS320F28335


Dear all,

By viewing the F28335.cmd and DSP2833x_Headers_nonBIOS.cmd file, I have some questions about CSM_PWL:

CSM_PWL     : origin = 0x33FFF8, length = 0x000008

Both page1 and page0 are allocated space, the address is the same, and the compiler will not complain. Which area will be allocated to it after compilation? Will this cause the chip to be locked?

thank you.

    It's not causing any linking issues because the application isn't trying to fill both the DSP2833x_Headers_nonBIOS.cmd-defined "CsmPwlFile" section and the F28335.cmd-defined "csmpasswds" section. For example, a project that uses the DSP2833x_CSMPasswords.asm file will use the "csmpasswds" section, but as long as nothing is placed in "CsmPwlFile", it will be ignored and there will be no errors.
