Dears,

Thanks a lot

Not without knowing which board, test code, development environment, and which JTAG interface you’re using.

Dominic

Hi Dominic,

The board is LPC2294

The develop environment is Kiel

The test code is provided by Kiel for LPC2294

and the JTAG interface is LPT

Thanks a lot for you concern

Hi,

it’s “Keil”, not “Kiel”. I’ve never used their software, so I wont be able to help you. AFAIK Keil doesn’t support Wigglers, so you’ll have to use H-JTAG as your RDI server, or use one of the more expensive interface supported by Keil (i.e. U-Link, U-Link 2, J-Link). Search the LPC2000 Yahoo Group, IIRC using Keil with H-JTAG was discussed there more than once.

Regards,

Dominic

What software do you recommend?

Thanks

I’m just evaluating Rowley Crossworks with an LPC2138 development board and so far I’m really pleased with it.

I use an Olimex (macgraigor) wiggler JTAG and it worked really well straight away.

The only downside I can see for Crossworks is the lack of example programs.

I’m using GNU tools under Linux with OpenOCD. I’m sure other tool sets work good also, but once you learn gcc and other tools you can use other processors without learning a new toolset, for instance AVR or MSP430 chips.

OpenOCD is first class software and provides all you need to program and debug.
