mkI clones are available at a wide range, starting from do-it-yourself setups. All you need is an ATmega16, a MAX232, and a 7.3xx MHz crystal. However, keep in mind that the mkI firmware is at its limit, and won't be developed further by Atmel. Thus, you are limited with any mkI device (regardless of whether a genuine Atmel one or any of the clones) to the AVRs supported by the existing firmware. The most recent AVRs supported by it were the AT90CAN128 and ATmega169. Anything newer (AT90CAN32/64, ATmega640/1280/1281/2560/2561, ATmega329x/649x, ATmega325x/645x, ATmega164/324/644) cannot be handled with it. Obviously, debugWire and AVR32 support are also only present in the mkII ICE. There has been some reverse engineering of AVRs private debugging JTAG instructions, and as a result the FreeICE project has been formed, but there doesn't appear to be have been any progress within the last couple of years. -- NEU: inter:gator Version 2.0 - intelligenter Finden: http://www.intergator.de J"org Wunsch Unix support engineer [EMAIL PROTECTED] http://www.interface-systems.de/~j/ _______________________________________________ AVR-chat mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/avr-chat
