When i use uboot boot linux, uboot read nand zimage, the speed of operation is very low !
U-Boot 2019.04 (Sep 02 2021 - 10:10:49 +0800)
CPU: Freescale i.MX6ULL rev1.0 528 MHz (running at 396 MHz)
CPU: Industrial temperature grade (-40C to 105C) at 47C
Reset cause: POR
Model: Freescale i.MX6 ULL 14x14 EVK Board
Board: MX6ULL 14x14 EVK
DRAM: 256 MiB
NAND: 256 MiB
In: serial
Out: serial
Err: serial
Normal Boot
Hit any key to stop autoboot: 0
NAND read: device 0 offset 0x500000, size 0x500000
5242880 bytes read: OK
It takes 5 seconds to read zimage data, no file system.
How to solve it？
Best regards
