I am using imx6-sololite based system based on EVK board. I was facing problem with boot because of low capacitance on supply voltage to core. I reduced the clock by blowing BOOT_CFG2 Fuse as follows
imxotp blow --force 5 0x08000430
Now, I would like to increase the Core and DDR clock either in uboot or kernel. Would you point me to peice of code that I can use to do the modifications?
