[U-Boot-Users] AT91RM9200 Timer Interrupts
Hi ,
We are using the reference design board from ATMEL AT91RM9200EK.
I currently see the u-boot for the at91rm9200, doesn't use the timer interrupts (cpu/arm920t/at91rm9200/interrupts.c)
Although the hardware timer is being configured to run freely, the timestamp value doesn't get updated unless the get_timer() function is explicitly being called.
We would like to know is there any specific reason why the timer interrupts are being disabled
Thanks,Balajee

Because they are not needed?
U-Boot is a boot loader, and doesn't use interrupts normally.

To implement get_timer() function for example. Can you suggest any other way to implement it in at91rm9200?
