[RFC] Integrating SEGGER SystemView into Mynewt
Hi,
I'm working on wiring SEGGER SystemView to Mynewt. "SystemView can
record data from the target system while it is running. The recorded
data is analyzed and the system behavior is visualized in different
views." More info here: https://www.segger.com/systemview.html
Right now it is possible to run the app and see some events, tasks,
interrupts. It's still work in progress and some things might be off.
I include a screenshot of the application. It shows the visualization
of events when using bletiny app.
I would love to get your feedback on some things:
- package structure, file and folder naming
- tracing api
- (current and future) placement of tracing api calls
I'm also having some issues with unexpected ISR events showing up. As
you can see in the screenshot there are some PWM, PDM, SWI4_EGU4 and
QDEC. The problem is I never made trace calls from these ISRs. In
fact, I couldn't find any usages of ISR with these IDs in the source
tree. ISR trace functions do not have ISR ID as an argument.
SystemView checks specific address when receiving ISR event, so maybe
there is something wrong with this address.
Anyway, here is the link to my branch:
https://github.com/michal-narajowski/incubator-mynewt-core/tree/systemview.
I'm looking forward to any comments.
Best regards,
Michał Narajowski

Seems like you put IRQn in description string instead of Interrupt ID so
they do not match:
https://github.com/michal-narajowski/incubator-mynewt-core/commit/2636b6027ebcbb73dfa36ab6129e087df4042ffa
The Interrupt ID is IRQn+16 so you just need to update numbers and it
should be fine then. See here for reference:
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0552a/Cihfaaha.html
(VECTACTIVE at the bottom).
BTW, this is probably why SysTick was set to 15 by default in mentioned
commit (it's IRQn = -1).

Hi Marcio,
I'm replying to the mailing list too because it is important. Yes, it
is possible to use SEGGER RTT console with SEGGER SystemView.
SystemView is using a different channel than the console. And you can
use it on my branch because SystemView was added on top of RTT.
Best regards,
Michał
