PASDK-432:Temporary fix SYS/BIOS crash in Event Combiner Dispatcher.
See sample_cs.c, edma3OsProtectExit():
EventCombiner_enableEvent(ccXferCompInt[edma3InstanceId][region_id]);
- ccXferCompInt[0][0] is set to 0x88.
- This causes overflow w.r.t. acceptable range 0-127 of argument to
EventCombiner_enableEvent(). Overflowed value is 0x8, which is event Id
associated with IPC.
- SYS/BIOS then expects IPC to be handled via handler associated with
Event Combiner instead of HWI #5.
No handler is registered for Event #8, so SYS/BIOS crashes.
