Hi DHANUNJAY

it can be changed running code from iRAM for changing system PLL,

check sect.18.5.1.3.3 System PLL, sect.18.5.1.5.3 PLL clock change

i.MX6DQ Reference Manual: http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf.

In runtime the same procedure can be used. For example bare-metal please

create service request.

Best regards

igor
