Hi All, In the document of "Porting Xenomai dual kernel to a new ARM SoC", section "flow handler" states: If the flow handler is “handle_edge_irq”, and the system locks up when the first interrupt happens, try replacing “handle_edge_irq” with “handle_level_irq”.
Could anyone explain why “handle_edge_irq” can cause system to hang while “handle_level_irq” doesn't? I searched the archives but failed to find any discussion on this topic. Thanks!
