I can't get interrupts on the ARM side in OMAP-L138 with SYSBIOS

Other Parts Discussed in Thread: OMAP-L138, SYSBIOS

I try to get interrupts on the ARM side in OMAP-L138 which works with SYSBIOS (from GPIO, for example), but I can't. These are some screenshots which helps to understand my configuration:

As you can see the flag from the periphery was raised, but the interrupt didn't occur. The global interrupt flag is enabled, the IRQ interrupts are enabled.

I don't call any special function in the code to enable interrupts, I think SYSBIOS should do it itself.

What is the problem?

I will look into your issue shortly.

That's correct, since you have "Enable at startup" checked then the Hwi itself will be enabled by SYS/BIOS.

I consulted a colleague about this, and he believes that the "Event Id" is not used for the ARM and that the "Interrupt number" should be set to 44.

The "Interrupt priority" of -1 should be OK, and the "Event Id" field is "don't care" (and I would suggest setting to 0 so as to not later believe that a non-0 value means something).
