Don't afraid. linker.cmd is simple. If you compare my file ahd original file you can see that I have done little changes. The line: .bflash_ext (RX) : ORIGIN = 0x7000, LENGTH = 0x0DFF # boot flash memory extension is to define the new segment in norm

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

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 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

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

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

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
