I realize now that I posted this thread to the wrong list.

I see now that there an RFC for multi-core support and a patch for refactoring armv7m_nvic - should I wait for those to be integrated? When will that be included into the mainline?

I'm trying to create a Atmel ATSAM4sd16c chip support (part of the ATSAM4 family) but I'm running into an issue with the NVIC code.  I modeled it after the STMicro implementation and created a Machine based around one of our boards, but I am running into an issue where although the call to armv7m_init() seems to set up the NVIC correctly and map it to 0xe000e000 and jump into the nvic_readl(), but never jumps to the vector in the firmware (kernel).   

Is there any documentation (other then code tracing) for how the interface for armv7m_nvic.c should be used?

Thanks much,
