Hi everyone:

I compiled uboot-2018 and used command `dd` to flash u-boot image, it outputs following

U-Boot 2018.03 (Dec 12 2022 - 15:46:27 +0800)

CPU:   Freescale i.MX6ULL rev1.1 792 MHz (running at 396 MHz)
CPU:   Industrial temperature grade (-40C to 105C) at 32C

Board: MX6ULL 14x14 EVK

switch to partitions #0, OK

The SD card's partition is following guide

p [lists the current partitions]
d [to delete existing partitions. Repeat this until no
unnecessary partitions
are reported by the 'p' command to start fresh.]
n [create a new partition]
p [create a primary partition - use for both
partitions]
1 [the first partition]
20480 [starting at offset sector]
1024000 [ending position of the first partition to be used
for the boot images]
p [to check the partitions]
n
p
2
1228800 [starting at offset sector, which leaves enough space
for the kernel,
the bootloader and its configuration data]
<enter> [using the default value will create a partition that
extends to
the last sector of the media]
p [to check the partitions]
w [this writes the partition table to the media and
fdisk exits]

What should i do next?

Hi @jax_wang,

Please provide me with the following details,

The command that you are using to flash the u-boot image to the SD Card and the u-boot image name.
Please try rebuilding the u-boot image.

Thanks & Regards,
Dhruvit.
