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)

fastboot key pressed
Fastboot: Got bootloader commands!
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?
