Hi, I'm using an ARM-JTAG dongle interface (which uses parallel port, and is Macraigor Wiggler compatible) to program a TMS470R1A256 on a TMS470-P256 board (made by Olimex). I have been able to load the application to RAM and to flash, but when executed from flash, the applicaton runs 16 times slowlier. Using the debugging feature of the ARM-JTAG, I have stopped the execution in both cases...


Best dev kits for ARM Cortex?

Hi I've started porting a project from an 8 bit AVR to an ARM Cortex M3 MCU. I'm reasonably comfy with AVR, but I'm new to ARM Cortex. I found an NXP part that looked great, price and feature wise. I purchased an inexpensive LPCXpresso dev kit. However, the drivers and example code is simply awful. Buggy and poorly written, so development is more like reverse engineering than making actual p...

Hi all, Amontec just released a new configuration of the RAVEN on the Chameleon POD. This configuration enables the use of the rtck (return clock) for all ARM -s series. In fact, the ARM7TDMI-s ( and other ARM -s ), like Philips LPC21xx, use the rtck signal to control the baudrate of the JTAG. This means you can debug software running at very low frequency, but this means too that ...

Hi! I want to port uclinux to a new ARM7TDMI board. I could borrow a ARM MultiICE 1.4 JTAG debugger connected to parallel port.

And/or - Can I use the ARM sw tools and the MultiICE and use the debug ...

Hi All, As an amateur embedded circuit player, I have used couple of AVR and PIC microcontrollers in the past. In these days it is not to hard to find small, ARM based ready to use embedded boards under $100. They seems to have faster clock speed then most of the AVR and PIC boards. Can anybody shortly compare ARM with PIC ad AVR interms of (a) performance (b) software support (c) pr...

Hi, sorry, when this is off-topic but I didn't really know what other newsgroup to use. A general question on the instruction set of the ARM processor: Many of the ARM processors provide a normal ISA (32-bit) as well as an compressed 16-bit ISA (Thumb mode). It's obvious that the Thumb instructions are smaller than the 32-bit instructions resulting in a smaller program code if merely t...
