Is there any interest in support for executing Python scripts at specific times during debugging with Atmel Studio ? I am currently thinking of providing hooks for:

H1. Calling a script when a breakpoint is hit (with "auto continue" if desired)
H2. Calling a script at reset (Launch, Reset)
H3. Calling a script when evaluating a watch expression (potentially changing watched expire)

In a script, one should be able to
F1. Eval a watch.
F2. Read/write memory and registers
F3. Print to the output window
+ all the features provided by the IronPython distro we package with Studio.

Please take contact if you have any interesting ideas.

I know we got told off for being hostile to developers but seriously, don't you think you should fix the existing product before adding new features?

"hooks" are always welcome but as long as the mechanism doesn't break anything else and it doesn't sap implementation effort from things like AVR Toolchain (most importantly) or fixing other issues in the eye candy (less importantly).

What, for example, are Atmel's plans for adopting 4.7.1? Now that the __flash mechanism and LTO seem ready for human consumption it'd be good to see them in a readily accessible toolchain that has support for a wide range of AVRs.

What is the rationale behind Python specifically?

(The hostile snide remark would be: Surprised you didn't pick VB scripting... :wink:)

As of January 15, 2018, Site fix-up work has begun! Now do your part and report any bugs or deficiencies here. 

No guarantees, but if we don't report problems they won't get much of  a chance to be fixed! Details/discussions at link given just above.

Cliff: Sorry, I am not involved with the toolchain and don´t know their schedule.

Johan: IronPython is already part of the Studio distribution because of ASF, so it was a good place to start.

We´ve fixed and are fixing a lot of bugs in the upcoming 6.0 release; meanwhile it is refreshing to plan for and think about new features. So your input is certainly appreciated.

So far I´ve seen people use scripts to:
- On ARM : support debugging in RAM by initializing SP and PC to custom values at launch. In Studio 6, solved by using a custom field in the Tool options pane.
- On ARM : reset peripherals on core reset. Now hardcoded for ARM in Studio 6
- On ARM: disable-enable interrupts when stepping. Coming as an option for all MCUs in Studio 6
- gdb, MS DevStudio ,etc : pretty print complicated structures. This one is a valid case for scripting in Studio 6
- tracepoints: do something when hitting a breakpoint. Studio 6 can currently print a message with variables, and optionally continue execution. Script support here would potentially allow for taking snapshots of memory space and vars and do intelligent diffs.

Have you seen a cool/useful use of hooks/macros in embedded debugging ? Speak out :)

Well I presume you know TI's "gel file" system?

Yahoo! I've wanted this for a very long time. This makes it enormously more usable. Still, can you add another option to make it perfect: Allow interupt routines to run, step only following the current thread?

Interrupts would be serviced whenever running freely, like when stepping over a function call, or running to next breakpoint. This may not be enough, but there´s the easy workaround of setting a breakpoint and run freely whenever you want queued interrupts to be serviced.
At least this is the theory. We´re anxious to see how this turns out in practice :)

Now I do, thanks :)
Fairly big chunk of functionality, but unlikely we will get time to implement anything of that magnitude. Interesting to note that TI split their IDE in a GUI bit and a debug server, not unlike Atmel Studio, and that they provide separate scripting engines for the two components.

You mean that even with an interrupt pending, I can single step without falling into the interrupt server, but if I step over a function call or run to cursor, the pending interrupts get served? Sounds like a very good solution. When this will be out? Next week, please? :-)

Except that theirs is based on Eclipse and is available for all operating systems :lol:

BTW if anyone here thinks AS5/6 is "bloatware" look at the size of my \Program Files\Texas Instruments\ in the following picture!

Admittedly this is because I have quite a few of TI's library code packages installed:
