Question, i.MX8M external clock sources

SLICE — Tue, 06 Nov 2018 06:06:21 GMT

Dear team,

Can I understand that the external clock sources which is written in your datasheet of i.MX8M(IMX8MDQLQCEC Rev.1, 3.1.4 External clock sources) are referred to the following pins?

CCM_EXT_CLK1 GPIO1_IO00 ALT6
CCM_EXT_CLK2 GPIO1_IO01 ALT6
CCM_EXT_CLK3 GPIO1_IO06 ALT6
CCM_EXT_CLK4 GPIO1_IO07 ALT6
(From RM, IMX8MDQLQRM, Rev.0, 8.1.1.1 Muxing Options)

Regards,

Miyamoto

Hello,

Yes, the mentioned in the Datasheet(s) "four clock inputs to the CCM from normal GPIO pads via IOMUX

can be used as the clock sources in the CCM", are the following:

CCM_EXT_CLK1 on GPIO1_IO00
CCM_EXT_CLK2 on GPIO1_IO01
CCM_EXT_CLK3 on GPIO1_IO06
CCM_EXT_CLK4 on GPIO1_IO07

Have a great day,

Yuri
