I.MX6UL running at 696Mhz

[zc_tee]

Hi all,

I now have the i.mx6UL IC that is suppose to run on 696MHz with me now (MCIMX6G2AVM07AB).

However, it seems that it is still running at 528MHz max.

From the kernel source code (kernel version 3.14.52),  the operating points seems like limited to 528MHz only (arch/arm/boot/dts/imx6ul.dtsi file).

                                    operating-points = <

                                                /* kHz   uV */

                                                528000  1175000

                                                396000  1025000

                                                198000  950000

                                    >;

                                    fsl,soc-operating-points = <

                                                /* KHz   uV */

                                                528000  1175000

                                                396000  1175000

                                                198000  1175000

                                    >;

May I know is there any patches for kernel 3.14.52 that allows the imx6ul to runs at 698MHz? Anything else that i need to change in the kernel source code to make it runs at 696MHz?

Thank you.

Regards,

Tee

Hi Tee

one can look at Linux 4.1.15_2.0.2 Patch "i.MX 6ULL@800M" on link
https://www.nxp.com/products/microcontrollers-and-processors/arm-based-processors-and-mcus/i.mx-appl...

https://www.nxp.com/webapp/Download?colCode=L4.1.15_2.0.2_iMX6ULL&appType=license&location=null&Pare... 

and make similar modifications for 698 option. Unfortunately I am not aware of such patches for kernel 3.14.52.

Best regards
igor
