TMS320F28027: L0 SARAM

Seven Han

hello，

Cause the program is relatively large, this space （0x008000-0x009000）is not enough. Can i put part of the program into 0x3f8000-0x3f9000? thank you very much。

Hi Seven,

I think address range 0x3f8000-0x3f9000 cannot be used as L0 SARAM is dual mapped to 0x008000-0x009000 & 0x3f8000-0x3f9000. The L0 memory block is mirrored - that is it can be accessed in high memory or low memory.

Thanks
Vasudha

Vasudha is right. L0 space is dual map so you can use only one of these two address range for code/data placement.
