Moooore advice

Started by Jannie du Preez November 21, 2007
Hello everyone,

We are just starting off here and need a little advice, It seems that as 
far as a GNU debugger programmer for ARM9 is concerned the OpenOCD 
system is the way to go, for this you need a DLC5 Jtag cable or 
equivalent, How slow is the DLC5 Jtag cable in practise, is it usable or 
will it frustrate me? Does any one have a Gerber file or a eagle board 
layout/Schematic for a DLC5 Jtag PCB. I know there are commercial 
versions available to purchase such as the ARM-USB-Tiny but I am eager 
to get going and live in South Africa where I can find no commercial 
system to work with OpenOCD. We did purchase a KEIL ULINK2 jtag unit but 
the cost of the compiler is forcing us to look at other options. I am 
fairly certain the KEIL UNLINK2 jtag unit will not function with OpenOCD.

Are there any other chips that have enough RAM and ROM to host a Linux 
kernel?

Any other options I should consider?

Thanks


Jannie

You can get a JTAGKey, or the Olimex ARM USB JTAG device, or even a cheap wiggler clone.

Can you mail order stuff? It's all available for shipping.

I think that's true. This is odd because the circuit for that device is widely known (at least for the first version of it).

AVR32. Go look at the Network Gateway board. I seriously doubt if you'll find a better price for a well supported linux board. http://edageek.com/2007/03/26/atmel-avr32-networking/ http://www.linuxdevices.com/news/NS2837651365.html Eric
