hello.

I am trying to create custom firmware for CM3588 NAS Kit Board.

So, I have the following questions about the emmc partition immediately after purchase.

Q1. The emmc partition of the current CM3588 NAS kit board is confirmed as follows. What I'm curious about is if I mount the spi flash physically and then write the bootloader (u-boot) to the spi flash, does the RK3588 read the bootloader (u-boot) of the spi flash first?

(parted) print list
Model: MMC A3A561 (sd/mmc)
Disk /dev/mmcblk2: 61.9GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number Start End Size File system Name Flags
1 8389kB 12.6MB 4194kB uboot
2 12.6MB 16.8MB 4194kB misc
3 16.8MB 21.0MB 4194kB dtbo
4 21.0MB 37.7MB 16.8MB resource
5 37.7MB 79.7MB 41.9MB kernel
6 79.7MB 113MB 33.6MB boot
7 113MB 147MB 33.6MB recovery
8 147MB 61.9GB 61.7GB ext4 rootfs


Q2. Another question I am curious about is what is the purpose of two partition below?

Error: /dev/mmcblk2boot1: unrecognised disk label

Disk /dev/mmcblk2boot1: 4194kB
