CCM_CLK1_P clock output 8MHz generating settings

prabhu1 — Wed, 28 Nov 2018 06:35:50 GMT

Hi man/sir,

I am using i.mx6ull processor I need to generate 8MHz clock output in pin P17(CCM_CLK1_P), pls can u help how to generate a clock from i.mx6ull (settings in internal processor).

Hi prabhu

allowable options are described in sect.18.7.18 Miscellaneous Register 1 (CCM_ANALOG_MISC1n)

i.MX6ULL RM, seems there is no 8MHz option.

Best regards

Hi Igorpadykov,

Thanks for the reply, but I want to get the clock in CCM_CLK1_P pin expecting 8MHz clock (p17 pin i.mx6ull) what changes (any exact registers & dividers in inside processor) or from 24Mhz external clock source how to get 8Mhz clock inside processor? and connections between CCM_CLK1_P pin(p17) & 24Mhz clock inside IC ?

Hi Igorpadykov,

I need to generate 26MHz clock output in pin P17(CCM_CLK1_P), pls can u help how to generate a clock from i.mx6ull (settings in internal processor). Do you know which register is used to configure this PIN ?
