Hi,
We're trying to bring up a new i.mx6q design and using DS-5 over jtag. The CCM_CBCMR (0x020c4018) register value observed is always 0x004A0324 and not 0x00022324 as indicated in data sheet.
Does the boot-rom modify default register values or is there some other setting (e.g. efuses) that we need to look at to know why our register values don't match defaults?
thanks,
Tarak

Yes, the boot ROM can change clock settings, using fuse parameters, please look at section 8.4.3 (Clocks at Boot Time)
and section 8.3.1 (Boot eFUSE Descriptions) of the i.MX6Q Reference Manual.
