Thanks to all... Turns out my error was not changing the default value for the PMST in c5000.gel which sets the MC bit to 1. *********** REPLY SEPARATOR *********** On 6/9/2001 at 9:24 PM Scott Barnes wrote: >Matt, > >> I should then be able to load my text segment into saram0-3 at >> 0x28000.

Do you specify Page 0 > with address 0x28000-0x2FFFF or Page 2 with address 0x8000-0xffff? It's the former. Don't let the word "PAGE" in the linker control file confuse you; the linker's pages are used only to separate program and data space. Program space is linker page 0, while data space is linker page 1. Also, be aware that overlays affect all program (XPC) pages, not just the first one. If the on-chip DARAM really occupies 0x80- 0xFFFF as you say, then the overlay will make DARAM appear at those addresses on every page. (Take this with a grain of salt, as I'm not familiar with the '5416 memory map.) Back to the linker: here is a snippet from a linker control file for the '5402. DARAM lives at 0x80-0x3FFF, and internal ROM is off (MP mode). ---- MEMORY { PAGE 1: SCRATCHPAD: origin = 0x0060 length = 0x0020 PAGE 1: FASTDATA: origin = 0x0080 length = 0x3f00 PAGE 1: INTVEC: origin = 0x3f80 length = 0x0080 PAGE 1: DATA: origin = 0x4000 length = 0xC000 PAGE 0: PROG0: origin = 0x8000 length = 0x7F80 PAGE 0: BOOTVEC: origin = 0xFF80 length = 0x2 PAGE 0: PROG1: origin = 0x14000 length = 0xC000 PAGE 0: PROG2: origin = 0x24000 length = 0xC000 PAGE 0: PROG3: origin = 0x34000 length = 0xC000 } ----- Regards, Scott

The same thing holds for using DSP/BIOS to handle memory management, define the segment with the address and in the linker call it Page 0 (for program memory). Brian ----------------- Brian C.

Can anyone "unconfuse" me? I'm using a 5416. I in MC mode with the overlays on. This mode should allow on chip daram from 0x80- 0xffff. I should then be able to load my text segment into saram0-3 at 0x28000. XPC=2, address 0x8000-0xffff. I'm confused how to do the linker command file for this. Do you specify Page 0 with address 0x28000-0x2FFFF or Page 2 with address 0x8000-0xffff? Or do you do it with overlays??? I cant find an example anywhere. thanks
