Hello Group, I am using GNU compiler for my LPC2136 & want to write a byte on some memory location.Previously I used the Real View Compiler for KEIL & there was a inbuilt command _wbyte(location,char) for writng the same.There is another command _at address for writing to a memory location.But when I use this command in GNU compiler,both of these command are not recognized & the program is not g...

Hi, Below is a simple startup sequence that fills the stack areas and initialises overall state, before jumping to 'C'. Please don't bother pointing out there are more efficient ways of doing this: I know there are. It gets the job done.... Note that this is designed to work with a GNU link file which reserves the space for th

I seem to be having problems trying to program my Phycore LPC2994 module when I use the GNU toolset. I have tried using both JTAG and the Philips utility, and neither of them will successfully program the chip. It will instead have the the previous program. If I used the Keil

There's been a few occasions (including one current one) of people looking for examples of the files you need to get a basic program up and running using the GNU tools. My question is whether there would be any interest in having such an example placed in the Files section of the group? I'd be willing to put a core together and make it publically available, to include: - startup.s fil

I'm looking for a good book or online resource that explains GNU GCC makefiles for the LPC2xxx series. Something that you may have used to learn makefiles not just a Google search result (I already did that). My dilemma is that I see many example code for WinARM, YAGARTS, CodeSourcery and the make files never seem to work unilaterally between then even though they all use GNU GCC. Thanks. ...

Hi, I'm using the EE_demo_1_1 on a 2194. I've chnaged the sectors in order to write in the 5, 6 and 7 sectors with addresses 0000A000 and 0000FFFF. I've also moved the BUFFER_SIZE to 512 etc. etc. All works fine. Now I'm trying to move the same example to be used with GNU compiler. The code hangs when the iap call is made, may be it's for different stack management from the Keil com...

Hi all, I need someone to point me to a tutorial on configuring gnu makefiles & linker scripts for the LPC2138. I just started using Sourcery G++ (an ARM optimized eclipse/gcc), but I honestly haven't found any information on how to set up the environment for a specific MCU. I stopped using scripts in the days of DOS, and until now my MCU projects have all been done with tools ...

Hi all! I have a problem that I can't fix with GNU ARM Toolchain and math functions. Maybe someone has experimented floating point math function with GNU ARM Toolchain and can help me... This is the problem: when using floating point arguments, some math functions cause a program crash with "data abort" or "undefined instruction". I've done some tests with the newlib math functions w...
