HI, ganesh
Do i have to enable clock as well when using TIMER_getCount()? If i enable
it, the same error message (invalid CIO command) comes out.
Thank you

HI, Ganesh
Thanks for your answer. When i use TIMER_getCount() as you suggested, i always get 0. I have read through the help docoment about CSL, configured CDB file, used TIMER_start(). Anything else needed to be done to get it work? Thank you Yong

Hi Yong,
You need to perform initialization steps for
the Timer Module before you can start the module.
Also send across your code, if possible. I
will try and see what is the mistake you are committing.
BTW, you needn't enable the clock. The
clock is enabled through the Software only.
HTH,
Ganesh

Hi, Ganesh
My code in main()
Uint32 start, stop;
CSL_cfgInit(); //initialization function generated by CDB TIMER_start(hTimer1); start = TIMER_getCount(hTimer1); .....//other code
stop = TIMER_getCount(hTimer1); printf("start: %d\n", start); printf("stop: %d\n", stop); printf("cycles: %d\n", stop - start); in videocfg_c.c generated by CDB file
void CSL_cfgInit()
{ hTimer1 = TIMER_open(TIMER_DEV1, TIMER_OPEN_RESET); TIMER_config(hTimer1, &timerCfg0); } thanks

Hi Yong,
Did you set the configuration parameters for
the module properly ? Are you using the correct CSL for the chip ?
Have you set the parameters of timercfg0
correctly ?
Perform a reset timer before you config
your timer i.e. TIMER_config.
Also one more important thing is that you
need to multiply the difference by 8 i.e. any output from the TIMER module is
scaled down by 8. You are missing the multiplication by 8.
Kindly verify the same.
Thanks and Regards,
Ganesh

Hi Yong,
Change the parameters to the following and
verify:
Control register : 0x000002c0
Period register: 0xffffffff
Count register: 0x00000000
Also you can perform TIMER_reset(hTimer) as
even though it might open the timer in Reset mode, manually performing a reset
won't harm.
Try these. It should definitely
help.

Hi, Ganesh
I tried these, but unfortunately all TIMER_getCount() values are still
0. I tried TIMER_setCount(htimer1, 0x55), then TIMER_getCount(htimer1), the
value is 0x55. It seems the timer register remains constant and doesn't
increment at all.
Thanks
Yong

Hi Yong,
I cant comprehend why you are facing this .
Instead of setting the TIMER in CSL set in software and check...
