Hello everyone,
I m using MV 4 and DM355 EVM.
I want to use timers and generate 1MHZ frequncy from GPIO pins.Using timer IRQS.
My quesions are
1-how to use high resoltion timers and its IRQ form kernel space driver ??
I have tried but some how the APIs in
/arch/arm/mach-davinci/time.c
#1. scedule_hr_timer_int
#2.get_arch_cycles
I am getting warning at compile time : scedule_hr_timer_int is undefined !!!
though I have added </asm/arch/hrtime.h> in my kernel driver code
I have also enabled HIGH_RES_TIMERS in my configurations.
It is getting initialised whie bootup I have also checked it using printks.
2- Is there any other way to use timers apart form High resolution timers ???
I just want timer interrupt at 1 Mhz from kernel space.
Please help.
thank you
