Compiler/TMS320F28069M: What different BIOS.cmd and nonBIOS.cmd

user5053976

Part Number: TMS320F28069M

Tool/software: TI C/C++ Compiler

Hi TI team,

I'm using F28069M and ccsv7.3

With knowledges and info about BIOS.cmd file and nonBIOS.cmd fil, BIOS.cmd include PieVectable so I don't need use InitPieVectTable() to init PIE vector and nonBIOS.cmd does not include PieVectable so I must use InitPieVectTable() to init for using PIE table interrupt.

Therefore, why we have 2 file option BIOS and nonBIOS instead of using file BIOS.cmd for all project with its convenient?

I think my question is a subjective questions but I usually think about this when I choose cmd file for my project.

Please help me

Thanks all a lots

Best regards

Hi Ozino,

I think I understood different about theory between BIOS and nonBIOS file but I cannot understand that why we have 2 file option BIOS and nonBIOS instead of using file BIOS.cmd for all project with its convenient?

In my opinion, we can use the BIOS.cmd file for every project.

I mean what pros and cons of these file.

Best regards,

Danh,

Since these .cmd files are from such an old product I'm having trouble locating them to help answer your query. Would you be able to attach the BIOS.cmd and nonBIOS.cmd (or just cut-and-paste inline)?

In general, the BIOS.cmd file could be defining symbols that are used by the BIOS PIE code which wouldn't be needed for a non-BIOS app. This would not have any impact on a non-BIOS app except for crowding the symbol namespace.
