Hello, My sw has overflowed pFlash1 memeory, and I want to put sw in pFlash2. Currently, I have already placed some constant strings in pFlash2, using the linker, and the AT command for Ext_Ram_Mirror. How will I add sw to pFlash2, and how should I handle the const data

Hello I need more than the 4K of X.RAM of my DSP56F807, I'd like to use P.RAM in the program memory. - What is the used of this RAM? Can I use a part of it to store some variables of my application? How can I specify the linker to locate my variables in this RAM.

Hello all, I need your help, since I am unfamiliar with the linker, nor could I understand its behaviour from the SDK. I am using internal RAM for data variables. I want to use external RAM (32K) for large data arrays, of two types: 1. One variable (r/w) da

Hi all. I need to place a large buffer in external RAM, let's say: int buffer[40000]; I declare it this way and it perfectly fits in memory. But when I want to make a reference to any element of this array above 32767th, for example: buffer[32768] = 0, the linker states an erro

Hi all, indeed, Peter described what happens and he's right - the CW *doesn't* check if your data exceed the size of pFlash. The thing it actually does is that it checks whether your data fit into particular MEMORY segment. However, this doesn't prevent your data from exceeding the s

Hello, I'm trying to build a stand-alone application that processes a lot of data that has to be stored in external data memory. I plan on using about 4MB of external data memory by expanding the 16bit address space with 5 GPIOs. My problem is that I do not understand how to setup th

I want to link in an interrupt vector table (written in C). I assume I need to create a special section - starting at 0x4 or what ever, and then link the table at this location. Specifically, how does one do this? I know how to create sections in the linker command file, and I

Hello again The previously posted advice works fine for non-string data, and by defining a separate linker section one can place constants in P-ROM: in the C source file, define the section and open it: > #pragma define_section mysection ".mysection.text&

I have a nasty problem where when I emulate everything works great but when I run out of flash it blows up. I've narrowed the problem down to some .asm files I have included in the project from the MSL. I need to do some right shifting and I included the .asm files from C:\Program Files\Metrowerks\CodeWarrior5.1\M56800 Support\msl\MSL_C\DS

Hi Roger, Here's how we do that sort of thing here (an example from one of our products, in the "linker.cmd" file). This example is for an '807 chip and external Data (X) memory, but the same thing will work for external P memory on the '803 and '805 chips. You do ha

I'm about to start development on a new product using the 56F8323, and I would prefer not to work within the CodeWarrior and Processor Expert environment. Are there any example projects using a basic make file to build with commmand line tools? I'm also after a register header file, linker file etc. Is anyone else working with the command line tools?
