WebQuite likely the issue here is that the ISR ends before the bus cycle for accessing the interrupt flag has completed. Just spending a bit more time in the ISR and clearing the flag as early as possible should help. You might also try if a synchronization barrier (DSB) after clearing the flag helps.

WebAs shown in Figure 2.1 (p. 4) each IRQ line can be triggered by one or more interrupt flags (IF).
