Re: [U-Boot-Users] How to add Timer Interrupt to u-boot?

Hi Robert,

Everybody knows how to add Timer Interrupt to the u-boot?

I wrote a fuction called timer0_isr(), and wanted to add it to Uboot, but I didn't know what to do, Does the uboot has a funciton like function request_irq() in linux kernel?

As Jerry told you, U-Boot generally avoids using interrupts.

For some architectures however we have code to allow using interrupts, e.g. from standalone applications. You can look at examples/interrupt.c which effectively was written with cpu/mpc5xxx/interrupts.c in mind. The latter was of course derived from the Linux version so it shouldn't be a big problem to do something similar for other architectures.

Cheers Detlev
