ECAP0 in APWM mode on OMAP-L138

Dear E2E:

Thank you for your help.

1.  I use ECAP0 and ECAP1 in APWM mode to generate the different CLK frequencies.

2.  I have no problem with ECAP1 which setup for the low frequency of 1/2Hs (0.25Sec_low and 0.25Sec_high)

3.  ECAP0 is setup for ~50Hz and it starts normally - only if SWSYNC bit is enabled and set SWSYNC=1.

4.  If SWSYNC is set=0 - ECAP starts with normal output frequency but after ~23Sec.

5.  The time of 23Sec is ~((2^32)/184.5MHz) where v184.5MHz is ECAP0 frequency (SYSCLK2)

6.  I could not find any explanation for this ECAP0 behavior - especially because ECAP1 starts absolutely normal with SWSYNC=0. But the same exactly setup does not work for ECAP0.

7.  Can you please help to explain this ECAP0 behavior?

Thank you very much,

Boris Ruvinsky
