David Sidrane 7c3850902f omnibus-f4sd nsh: Disable ARCH_IRQPRIO & ARCH_HIPRI_INTERRUP ... This insures the common exception handler will not be re-entered. The handler does not support nested interrupts and the interrupt stack pointer and context will be overwritten resulting in hard to debug hardfaults. If all the priorities are equal the NVIC prevents the preemption. The startup code defaults all the priorities to the same value 128. This change safeguards in 2 ways 1) By disabling CONFIG_ ARCH_IRQPRIO: up_prioritize_irq cannot be called. This will insure that all HW interrupts are at the same priority. 2) By disabling CONFIG_ARCH_HIPRI_INTERRUP, the common exception will disable any interrupts during interrupt processing.		7 years ago
