I’ m trying to speed up boot time and noticed that loading the kernel takes a lot of time:
[2.039394 0.001543] Read 5616192 bytes from volume kernel to 81000000
[6.389443 4.350049] No size specified → Using max size (52395)
Is the Read speed bound by the nand or bound by cpu speed?
Is there a patch available for uboot to run at 528 instead of 396 Mhz and/or speed up the nand?
Compared to a vf50 colibri the kernel takes forever to load, i don’t understand the big speed difference.
I’m running U-Boot 2020.07-5.3.0-devel+git.68f97c8d17f0 (Jun 24 2021 - 07:52:49 +0000)
