Hi, I start my adventure with uC with arm7tdmi-s core.I presonally use lpc2114 but I have tested some example for lpc2138 and I think: where can I change position of top stack (which file)?? because my uC has only 128kB flash and 16kB SRAM. When I have used a Eclipse environment, I've done it in file boot.s ( .equ Top_Stack, 0x40004000) but in WinARM i can't see this! maybe it is done automatically? but I don't know that? because in Eclipse if I don't change it, a program does't work and in WinARM it works!?? Please anybody answer me on this question :) Thanks P.S sorry, if I did a lot of mistakes in this post, but my English isn't very well :):):)
It has nothing to do with WinARM or Eclipse. The first is a toolchain and some utilities, the second is an IDE into which you can integrate pretty much any toolchain. There is no one way to do this, and it is entirely dependent on your project and how you have set it up. If you are using or started from any of the examples provided with WinARM, then I believe that the stack position is determined by the linker script (and this is probably the most common method). I believe the file is probably called "ldscript" or similar (No WinARM installed here and I don't use any of the WinARM examples or scripts - none are much help on a Samsung S3C2410X - so I am not sure)
