Hi, experts:
I have a question about IRQ statck pointer alignment.
In arch/arm/lib/interrupts.c :
In Interrupt_init(void) function:
IRQ_STACK_START = gd->irq_sp - 4;
IRQ_STACK_START_IN = gd->irq_sp + 8;
FIQ_STACK_START = IRQ_STACK_START - CONFIG_STACKSIZE_IRQ;
It seems not do alignment operation for IRQ_STACK_START /
FIQ_STACK_START .
Best wishes,
