I'm using ADC0 with interrupts on CPU0 which works good, but when i enable USB FS Host on CPU1 i get random crashes on CPU0.
What happens is that the ADC0 irq is triggered but the fifo is empty.
It seems like it's a spurious irq but if the irq is just ignored there will be no additional irq that signals that data is available on in the fifo.
CPU0 runs in secure mode and CPU1 uses the unsecured memory space.
Could there be an issue with using USB-FS host and ADC0 from different cores?
I see that both are connected to the same AHB bus and both are also quite close in the memory map.
