How i.MX6SDL AXI_CLK_ROOT is created?

Hi community,

I have a question about i.MX6SDL CCM.

I confirmed EIM ACLK(aclk_eim_slow) is created from AXI clock root (396MHz) in Which frequency is correct for i.MX6SDLACLK_EIM_SLOW_CLK_ROOT? .

However, according to the reset value of CCM_CBCDR register (chapter 18.6.6 in IMX6SDLRM Rev.1), AXI clock root seems to be created from PLL2 396MHz PFD.

In addition, in Figure 18-2, AXI_CLK_ROOT is same as DTCP_CLK_ROOT, but the default clock frequency of DTCP_CLK_ROOT is 270MHz in Table 18-3.

So I'm confused how AXI_CLK_ROOT is created.

Would you let me know what is correct?

Best Regards,

Satoshi Shimoda

Hello Satoshi Shimoda,

I'm sorry for the late response. There is an Excel i.MX6 Clock Configuration aid which may be useful to clarify some questions, do you have access to this spreadsheet?

Hi gusarambula

Could you please send me this Excel sheet for clock config? This sounds very helpful!

Thanks in advance,
