d0cda60442 In the current implementation we only use very high priority interrupts (levels 0, 0x10 and 0x20 in CORTEX-M speak) but that means there are loads of lower priority ones that are effectively unused. I have *not* changed the semantics of these levels but have 'shifted' them to be based around the midpoint of the available interrupts (0x80) rather than at the top end....that allows for interrupts to be defined above (or, indeed, below) them as needed by the application. This should have no functional effect on existing code but adds in a clean capability to define higher priority interrupts. 2018-12-03 17:41:59 -06:00

a6682a9bef Squashed commit of the following:
arch/arm/src/max326xx and configs/max32660-evsys/src:  Fix some issues with GPIO setup of output pins.  Correct polarity of on-board LED output.  The on-board LED is now functional.

    arch/arm/src/max326xx: WFI instruction in IDLE loop seems to interfere with stability.  Commented out for now.  Needs to be investigated further.
