Other Parts Discussed in Thread: OMAP-L137

Hello.  I'm interested in interacting with another device via u-boot.  I've done som research and I don't see how I can utilize an interrupt handler via u-boot and the OMAP-L137.  Any suggestions/help would be appreciated.  Thanks.

    Hello,

    AFAIK, U-Boot in general does not support interrupts. All the peripherals are implemented in polled mode. I have not heard of an instance of anyone using interrupts in U-Boot and adding support for interrupts would be involved task (need to take care of context switching etc).

    Thanks,
