Hi, We've written a Windows 2000/XP based IDE (called ArmEd) which interfaces with the GNUARM toolchain & Insight debugger. It also uses OpenOCD to interface to the target JTAG port. You can create and configure projects very easily, then build, download & debug them. The IDE was developed for use with a LPC2214/FPGA development board but can be used with other LPC2xxx targets. An ...

I am customizing my makefile for use with the latest GNUARM C package. Is it possible to evaluate a simple mathamatic expression like this: .... UND_STACK_SIZE = 4 FIQ_STACK_SIZE = 0x100 # this does not work because it does substitutions. STACK_SIZE = $(UND_STACK_SIZE) + $(FIQ_STACK_SIZE) How do I ask make to evaluate mathamatically instead of symbolically ? Any advice ? Than...

Hello I'm working with gnuarm tools and a LPC2148, and i've a little program just to send you a feedback from a uart received char, based on the uart IRQ. The problem is that i can't get the ISRoutine working even when the program gets compiled without any warning or error. Could any one give a little help please?.. The declaration: unsigned long uartInterrupt (void) __att...

Hello to the group. I'll introduce myself as a hobbyist at this point (although we _are_ using one Armite on a quasi-regular basis at work). Leon Heller mentioned this group in a post in the sparkfun forum, and I see some posts here by rtstofer (thanks again for your help in the gnuarm forum Richard). Has anyone here used the philips VCOM driver for the lpc2148 on XP lately? It is included...

Hi, Newbi here. I have a GNUARM install with newlib and was wondering where could I find some delay routines. That are more or less precise to my LPC2103 system clock. Meaning it knows the actual clock speed and calculates the delay routines accordingly. Like delay_us(int) or delay_us(int) etc would be nice. Or if I already have it what library should I include. I have been looking here sin...

Hello I try to run simple circuit with LPC2138 chip. I plan to use lpc21isp utility to flash it under Linux. Yesterday I installed GCC-4.0.1 from gnuarm.com, BUT I did not find lpc2138.h, startup.S and .ld files to build code for FLASH and RAM of LPC2138 chip.

Greetings: I successfully completed James Lynch's excellent tutorial using an Olimex LPC2148 header board. I was able to flash a LED by executing the gcc compiled examples loaded into either RAM or FLASH memory. However when I try to expand the tutor example by adding calls to library functions I find I get loader errors. It would appear the loader is able to find the object code ...

I am developing firmware for a custom LPC2138 board, using GNUARM/Eclipse. The project is at an advanced stage, nearing completion. I am using custom start up code, and a custom linker script. However, the entire project must run as a 'managed make' under the Eclipse GUI. I am not allowed to create stand alone makefiles. As I mentioned, I have a very effective code running on the ...
