Part Number: SK-AM62P-LP
I have tried adding the bootargs that supposedly reduce the boot time by 8+ seconds from the SDK AM62Px Linux Developer's Guide:
U-Boot=> setenv bootargs 'console=ttyS2,115200n8 fsck.mode=skip sysrq_always_enabled quiet'
And there seems to be no difference between the boot time with or without the bootargs. I am using the default image, and I have also tried this with the device tree method too, getting the same result.
Is there something I'm missing?
