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,-Jim
