I am looking very seriously at using the STR912 for an embedded Ethernet application. I want to use Olimex’s ARM-JTAG debugger, but their STR912 board is way overkill for my needs. The STR9 Dongle at DigiKey for $72 is a much better fit. There is also a new $49 COMSTICK, but I don’t know if it has an external JTAG connector and think it probably doesn’t. The goal of the COMSTICK is to coerce you into using Hitek tools.
Does anyone know if there is software already written that is compatible with OpenOCD and the GCC toolchain for the STR9 Dongle with working Ethernet?
For what it is worth, I am ultimately going to go with UDP communications.
Thanks!
The Hitex STR9 comstick is supported by opencod, it has integrated jtag dongle.
The ST dongle (497-5859-ND) will require a external jtag dongle to use it.

Thank you for your reply. One requirement for my ARM processor is that it serve as a communications coprocessor for a DSP. They will communicate over SPI and I have a need for the micro to be able to communicate rapidly over SPI. I would like to approach the 20 MHz pin limitation of the DSP. Well, I was floored when I found out the 912 can only operate at 4 MHz in SPI mode. This is much too slow. 12 MHz is probably the slowest I want to consider going at, and near the 20 MHz would still be better.
