I have measured the voltage of TP702 in imx6ul-evk is 1.4V, but CPU frequency is only 396MHz in U-boot. Are there any way to set it to 528MHz? BTW, I can not understand the meaning of following description in imx6UL RM p.157:
Target frequency of the core (including Neon and L1 cache) is 528 MHz non-overdrive
over the specified temperature range:
• 528 MHz non-overdrive over the specified temperature range
Thanks for explanation.
