I have a curiousity question. I built the gnu arm toolset on one machine and used it for a while. Then I built it on another machine which runs a different...
Hi All, Just wondering if anyone on here has any experience of linking code for RAM execution (during development) against pre-built library functions in ROM...
... I was thinking about this to other day, believe it or not. I think you can do this a couple of different ways: 1. Compile/Link your program as an entire...
I'm having the same problem. I'd like to know how registers are used, assigned to variables, etc. Is there a document that explains the compiler to assembly...
... Be careful! I often use the gc option to strip dead code that would change the image layout. ... That is what the -j and -r options in objcopy are for. You...

... Why? I really struggle to see this as a valuable engineering exercise and if it is an academic exercise, well the gcc code is there to download :-). About...
Hi All, I am trying to understand what this does in the linker script *(.glue_7) *(.glue_7t) I can't find any references to this section. Any pointers would...
... Looking at that, my impression, is that I would say that that is for interworking Sections. I use a mix of ARM32 and Thumb code in this one project, check...
I was wondering if anyone had any experience with the Sam7X and Sam7S/Sam7A3 and could determine if either one was better. Basically, I've noticed that the...

Compile a piece of code and read the assembly code. Pretty much all variable passing is done in the same manner except some are pointers and some are data. dh...
... Hi, I think you are unfair about the AT91 series from Atmel. I think they are superb microcontrollers, because: - the peripherals (except perhaps for the...
I've never looked at Philips documentation, but if its worse then the AT91 series, it must be really bad. The documentation for those things is pretty ...
Hello... Is there someone working with an LPC2888. I am trying to use the GNU ARM toolchain, but I am experiencing some problems writing a linker script and ...
I never used Atmel ARM devices, but have a few experience with NXP parts. Now there are models with USB, and almost all new devices have a fast IO mode that is...
Hi, Im after some advice regarding ICE. I would like to be able to use MCU's from Atmel and Philips with ARM7, 9 cores (possibly the Analogue Devices ARM7...

CodeSourcery made some gcc extensions for the Cortex M3 (about 15 months ago, I think), but I never heard if these were rolled into the main gnuarm release? If...

Yeah its the driver issues that were of concern but as you say it could be grounding issues. What unit do you use? The appeal about the segger is that there...

The Segger is a very nice product but dedicated for the ARM7/ARM9. By its concept, the Amontec JTAGkey has the advantage to be an un-dedicated JTAG solution. ...
