I just went from a 5402 to a 5416 because the 5416 has more on chip RAM. I set the MP/MC=1 and OVLY=1. If my .text fits below 0x4000, everything is fine. If .text grows so that some is below 0x4000 and some is above 0x4000 (but below 0x5000) I keep getting runtime errors. The linking is always OK no matter what. Is there something special I need to do to use 0x4000 to 0x7FFF? Can anyone suggest anything to help? Thanks! |

With C5416 there should be no issues with prog mem until you hit 0x8000, then you have possible DROM and other data mem related considerations. My guess would be that you have some buffers or other memory usage made outside the scope of what the CCS linker knows, and there is a conflict. Please study the .map file carefully and see if you can get some clue as to what else might be using mem at 0x4000. Jeff Brower system engineer Signalogic |

Can you post your map file? It would help.
