Hi AVRs

some people have contacted me asking where the JTAGICE schematics is -
it seems that the original URL where it was is not available and that also
links to it are cleared in Google cache, real achivement from Atmel side
if they really did force google to clear the entries. The originally posted
JTAGICE schematics (original drawing from Atmel), was initially released
by Atmel, and did not have _any_ copyright notices. Still - as Atmel sees
that as a mistake they made - I am not making the original drawing available
(actually its deleted from my desktop) - well to make its own ICE that can
be BOOTed to mimic Atmel JTAG*ICE can be made without so or so - there
are several people who have done it and it functions well. From historical
reasons I attach the photo of the first proto that worked as JTAG*ICE
on the photo the big-green is JTAGICE (with ATmega163) and the smaller
PCB is target device being debugged (ATmega16), both have ISP connectors.

antti wishes happy ICE age!
BTW it was to my surprise that PICers are doing self-made PIC ICE boxes
for years, MPLAB 5 had the firmware for Microchip ICD debugger :)

This attitude of the uC companies really irks me. We've got a whole bunch of ideas that could produce some really cool application that would *support* companies like atmel, but they all refuse to open their specification... funny how a "standard specification" can get so "un-open"!

Anyway, Atmel is not the first I've been dissapointed in with this attitude and IMO, they are only hurting their own market.

well atmel has a short list of friends - those who are not on the list are not
treated as 'possible friend' but directly unfriendly. This personal experience.
People who spent weeks and months hunting down silicon bugs on Atmel
product, and report them to Atmel land automatically on no-friends lists!
Everyone has of course freedom to select their friends. Atmel seems to
have made wrong choices - Kanda (biggest friend) is doing collapse, and
Equinox who always felt that is not big enough friend seems to have discontinued
almost all AVR related products (i.e. stopped new development for Atmel).
And new friends are not recognized - so the Atmel user community really
cant expect that Atmel supports companies and people who would create
tools that do benefit Atmel. This is silly.

Make that a VERY short list of friends ... Their attitude is well beyond my power of understanding. Thank you again for your ICE schematice, Antti. Talking about mistakes, the ICE one is not at all singular. Some while ago I downloaded a support file for their ARM microcontrollers (please note that anyone at all could download it at that time) and I found there (among other things) the sources for ARM Angel Debug Monitor, a complete VxWorks library, uC/OS-II sources and others ... Needless to say, all these things cost money in the real world. So this wonderful people at Atmel don't have many friends, but on the other hand they don't seem to be too bright ...

ROTFL, yes, I found registration key to WinDriver also in Atmel distribution :)
shortlisted.
well there was Kanda, kinda of.
all others even friends have had trouble that friends dont have.

the "beyong power of my understanding" is a very good comment -
I heard the german version of it recently so its kinda common thinking.
Thats actually kinda sad for the AVR community.
