* By reading 0x120100E4 You can see CPU The frequency of has been configured to ：
A53：1188MHz
A73:APLL FOUTVCO;(FREF x ( fbdiv + frac/ 224) / refdiv) , The calculation must be greater than 1000Mhz Of ,
This register is directly in the uboot Configuration during startup ,
But through cat /proc/cpuinfo See in BogoMIPS The content of 100M
By analyzing the code, you can know that this is calculated , change lpj The value of the BogoMIPS The value of the
modify
setenv bootargs 'mem=512M lpj=240000 console=ttyAMA0,115200
root=/dev/mmcblk0p3 rootfstype=ext4 rw rootwait
blkdevparts=mmcblk0:1M(boot),10M(kernel),1024M(rootfs) '
See is BogoMIPS yes 480M
Revised as ：
setenv bootargs 'mem=512M lpj=500000 console=ttyAMA0,115200
root=/dev/mmcblk0p3 rootfstype=ext4 rw rootwait
blkdevparts=mmcblk0:1M(boot),10M(kernel),1024M(rootfs) '
See is BogoMIPS yes 1000M
Why is it not in accordance with the actual situation clock How about matching ?
