@all,

Subject: XMega PDI Debugging ready for use  -  Posted: 14.06.2012 - 18:13   -  
@all
:tanz: :blob4: XMega PDI Debug/ICE in-circuit emulator

Beta version for the XMega PDI-debugging (ICE) is ready now.
It consists of the enhanced AVRsim (Simulator) and a
firmware update for the programmer ISP3 debug versions.
The most important functions are working:
  • Run
  • Stop
  • CPU Reset
  • ASM single step
  • Pascal single step
  • Breakpoint in the ASM window
  • Breakpoint in the Pascal (source) window
  • Update of the registers (R0..R31) on a stop
  • Update of the IO-registers on a stop
  • Update of the variables on a stop
  • Changing of the registers, IOs and Vars by the user within the SIM.
Not ready yet:
Data BreakPoints.

Breakpoints:
All Xmega provide only two internal breakpoints. If more are
necessary then the user must insert them into the source as
fixed breakpoints with this:
Pascal: Debug_Break
ASM: Break
These breakpoints can permanently reside in the source because
they are only recognized by the XMega if it is in the debug mode.
So the count of the breakpoints is unlimited.

The programmer ISP3 Debug must be updated with the included
firmware. Attention: older ISP3 Debug (before mid 2011)
must be updated by E-LAB. The firmware date can be seen in
the AVRprog by clicking the button with the magnifying class.

The Merlin optimiser supports debug_break, but is slightly less efficient because delayed memory write is not implemented when this directive is present.

@all,

the current AVRco update/download contains all necessary components for XMega PDI in-circuit debugging.

Hello Rolf,

my ISP-3 Programmers were sent in to e-lab last year for updating. I have added the information from the magnifying glass as a pdf. So, do I have to send in my programmers again? Their status is slightly before "Mid 2011"?

Regards, Michael

@all,

the new (revised) XMega128A1U are available now. But please be careful.
These device have USB on board but show all the earlier bugs and problems
of the first XMega generation. A long list of bugs in the current datasheet.
The current chip release is "L".

If you want to have a real working USB, ADC, DAC etc. then wait for the
final silicon release >= 'M'.

poor performance of Atmel (as often usual).
At least they treat the erratas not as "top secret" :bandit:
(like Mega256x and PDI debugging --> :P infos)
