Linux BSP reconfiguration to use another timer for OS ticks

Other Parts Discussed in Thread: AM3352

Hello all,

Our customers are using AM3352 processor in their product and we are working with them on porting Linux to their board. They need 1ms timer for their hardware and are asking Linux to use Timer0 for schedule ticks.

Can we disable timer1 in Linux and configure the board initialization code to use Timer0 for schedule ticks?

Thanks and regards

Rajam

    Timer0 runs from an RC oscillator is not reliable to be used as the primary clock for the kernel. Moreover, the current implementation in PSP releases is the most optimal one for AM335x. Any change here will throw up some or the other issue.
