Hi all, In my project I use a bootloader which forces my user-code to place it's vectors @ 0x40000000. But this is apparently easier said than done... I searched through Yahoo's group history and also on Rowley's faq. However, I'm not closer to the solution. I believe that the c runtime initializer would be able to copy my vectors to ram, but so far I haven't succeeded. I changed...

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.

Yes I know the issue of IDE choice is often discussed, but please bear with me on this. I'm a relative newbie with Philips lpc2xxx, but reasonably familiar with PIC microcontrollers. So far I have been playing round with the demo (16k limit) of the Keil uVision IDE + their jtag, and I am coming to the stage when I have to pay real money for a full IDE / compiler
