Hello Everybody, I have bought an Olimex LPC-P2129 prototype board, an ARM-JTAG Dongle and I have downloaded a trial version of Rowley CrossStudio. I am able to write a small program to flash a LED and that works. I am now trying to work with the CAN capabilities of this board, but I can't seem to get it working. Is there maybe someone who can he

Hi, I recently acquired a CrossConnect for ARM, along with CrossWorks. I have developped a prototype board using the same JTAG system as MCB2300 from keil. The board power is working fine, at 3.3V. However, every time I try to program (fresh programming) the LPC2368, I allways get the "Cannot identify target" annoying message. I have already tryed with 1, 10 and 100 clock dividers, every one wit...

Hello: I'm using an USB Bootloader and want to run a FreeRTOS application which works standalone (with no bootloader in flash). However, if I burn the bootloader onto my LPC2148 and then load the FreeRTOS app (linked in the starting address 0x2000) it will eventually provoke a Data Abort exception. I tried to trace it with the JTAG but I think that I might be breaking the normal behavio...

Hi! I am now deciding on which IDE and compiler to use and with that I have done some searching over the net and came across some tests that were made with IAR, GNU and KEIL compiler and according to that report the GNU compiler was the best out of these three. With this I found CrossWorks that should provide GNU compiler support and debugging over JTAG. Since I have already bought MC...
