Read-Only Author Lucas Machado Posted 11-Jan-2005 11:43 GMT Toolset None	Using C16x DPRAM Lucas Machado Hello; How can I use DPRAM in XC167? I mean: how to correctly link a RAM memory area (in this derivative, 0xE0'0000 - 0xE0'1FFF) into one of the CODE target classes? My problem: I followed all the linking steps in AppNote #138, including the SROM class and the FLASH_CODE section directives: SROM (0xC00000-0xC1FFFF) ?PR?PFLASH%FLASH_CODE (0xE00000) [!] I have also added in the External Memory #2: RAM : 0xE00000 - 0x1FFF* But the debbuger still doesn't execute any code in this area (because uVision fits RAM External Memoryinto DATA classes). If I add DPRAM as a "ROM" External Memory, my routine won't copy code to this area! It seems like the ?PR?PFLASH section* isn't working properly, has anyone a clue? Thanks in advance, Lucas

I'm still not sure about my application, which is highly adapted from the AppNote #138 and the program you stated. Does the "acces violation error" related to it mean this is a just debug error, "not automatically detected by µVision2" (as is in the HTML help) and it won't be an effective problem when I run this into the XC167? FYI, the routine does not copy buffer data into the address I want. I consider the main question is : is the On-Chip Program Flash Module fully simulated by uVision? Thanks in advance, Lucas

Read-Only Author Keil Reinhard Posted 14-Jan-2005 13:36 GMT Toolset C166	RE: Using C16x DPRAM Keil Reinhard Use the MAP command as indicated in my answer to tell the uVision where you are using memory. uVision does not (yet) simuluation the in-System Flash programming feature of the XC16x devices.
