About IPU clock source in i.MX6DQ.

[keitanagashima]

Dear Sir or Madam,

Hello.

Refer to Figure 18-8. Serial clock generation (Page.828) in MCIMX6DQRM(Rev.2).

I couldn't find the clock source of "ipp_di0_clk" & "ipp_di1_clk".

Is it external clock? And, please tell me the PAD which input the clock for IPU.

Best Regards,

Keita

Hi Keita

according to internal CQ (CT 44041259) design showed the following information:

for the ipp_di0_clk:
Alt2 of pin EIM_DA14 weim.WEIM_DA_A[14] ipu1.DI1_D1_CS ccm.DI0_EXT_CLK

for the ipp_di1_clk:
ALT2 of Pin EIM_DA13 weim.WEIM_DA_A[13] ipu1.DI1_D0_CS ccm.DI1_EXT_CLK
or
ALT2 of Pin EIM_EB2 weim.WEIM_EB[2] ecspi1.SS0 ccm.DI1_EXT_CLK

Hi Igor,

Thank you for your reply.

i.e. "ipp_di0_clk" & "ipp_di1_clk" are able to select and use as external clock from above PADs, aren't it?

(Is previous your answer mistake? It has already removed.)
