RE: [avr-gcc-list] r-engineering the JTAG-ICE protocol

[J.C. Wren]

        I guess one could.  Depends on whether that image replaces the entire
contents, or just some small portion.  From a legal standpoint (assuming
Atmel cares at all), disassembling code might be construed as copyright
infringement, whereas reverse engineering by sniffing the signals isn't.
Pure speculation, and just something we *may* want to keep in the back of
our minds.

        Of course, this problem would be a little easier if Atmel would just
exhibit some common sense like everyone else that supports JTAG, and release
the relevant commands.  I *personally* care little little about the
debugging commands, but care a lot about the programming sequences.  But
then, I debug the old fashioned way, with printf() and I/O bits.  I've
always found gdb to be extremely cumbersome.

Hi John,

is it not possible to dissasemble the JTAGICE firmware? Or what kind of file
is the Upgrade.ebn? As I see in my JTAGICE a normal ATmeg163 is inside.

Regards,
Juergen
