Hi TI

I have a project where my linker cmd file complains about the .bss.

How can i make some more space for it?

Can i combine SRAM so i just make one memory location called SRAM with the legtht F800? or do i have to have 4 S0RAM, S1RAM, S2RAM, S03RAM memories with 3800, 4000, 4000, 4000 length?

Or can i put .bss in another location than SRAM?

You can combine different memory section into one and assign the section is is not fitting into on RAM block.

So if i understand, this is the same?:

S0RAM : origin = 0x20000800, length = 0x00003800
S1RAM : origin = 0x20004000, length = 0x00004000
S2RAM : origin = 0x20008000, length = 0x00004000
S3RAM : origin = 0x2000C000, length = 0x00004000

SRAM : origin = 0x20000800, length = 0x0000F800

That is correct.

Just one note that these RAM blocks are accessible from CPU as well as uDMA and EtnerNET DMA so when you combined them in one block then code/data allocated to this RAM section may split across different RAM block hence may provide different access time based on the arbitration.
