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). > 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 > Best regards, Andrzej
