not work Generic Timer

syuchan

I am working Own RTOS on FireFly-RK3288.

I have problem.

I want to use Cortex-A17 Generic Timer(CP15 c4 registers).

But, Even though timer is enabled, not work counter.(countup/countdown not work)

ID_PFR1's generic timer extension is 'implemented'.

What do I need for?

Same initialization-code is work on cortex-A7 development board.

can you try my u-boot binary from http://androtab.info/rockchip/u-boot/ ?

if you're using own loader code, try to init TIMER7 like this https://github.com/linux-rockchip/u-boo ... c6f60332c9
