Issues about DDR Freq on Boot

[tony_l_cai]

Hi all,

     How can I get the DDR Freq on u-boot stage? And I want to know the DDR freq on u-boot. I also want to change the DDR Freq to the max freq, can you help me?3Q~

  You may use U-boot command “clocks” to get information about DDR frequency.

To change default after reset configuration of i.MX6, DCD table may be used.

Please look at the following :

Also, please refer to i.MX6 Reference Manual, boot chapter for more details.

Have a great day,
Yuri
