Generate clock frequency of 26MHZ

velayutha_perum — Sat, 27 Jul 2019 07:05:33 GMT

Dear Team,

I am using Imx6ull in our design. I want to configure this pin CCM_CLK1_P to give output of 26MHZ? But when i search like CLK1_P, I can see this bit in 5 to 6 registers. I do know to which register we have to enable it.

My requirement is i need to generate 26MHZ with this pin.

Can you help me on this?

Thanks

Peru

Hi Peru

one can try to output clock CLKO1,2 using CCM_CCOSR register, described in

sect.18.6.21 CCM Clock Output Source Register (CCM_CCOSR)

i.MX 6ULL Applications Processor Reference Manual

Use divider CLKO1(2)_DIV : /8, 26MHz *8=128MHz and

generate 128MHz on some unused clock, for example "sai1_clk_root" or

spdif0_clk_root, depending on application.

Best regards
igor
