Device Management
This document introduces how the SDK manages devices, including the configuration files of devices, how to add new devices, and how to achieve adaptive support for different devices through EEPROM.
Configuration Files of Devices
A device (Device), also called a board or board type. Taking DEB1 as an example, it corresponds to BPI-F3, and usually includes the following configuration files:
bsp-src/uboot-2022.10/arch/riscv/dts/k1-x_deb1.dts
bsp-src/uboot-2022.10/arch/riscv/dts/Makefile
bsp-src/uboot-2022.10/board/spacemit/k1-x/configs/uboot_fdt.its
bsp-src/uboot-2022.10/include/configs/k1-x.h
bsp-src/linux-6.1/arch/riscv/boot/dts/spacemit/k1-x_deb1.dts
bsp-src/linux-6.1/arch/riscv/boot/dts/spacemit/Makefile
buildroot-ext/configs/spacemit_k1_defconfig
buildroot-ext/board/spacemit/k1/env_k1-x.txt
bsp-src/uboot-2022.10/arch/riscv/dts/<board>.dts
The dts of the device in u-boot.
bsp-src/uboot-2022.10/arch/riscv/dts/Makefile
The Makefile of the dts of the device in u-boot.
bsp-src/uboot-2022.10/board/spacemit/k1-x/configs/uboot_fdt.its
The configuration file of the u-boot FIT Image.
bsp-src/uboot-2022.10/include/configs/k1-x.h
The configuration of the K1 chip in u-boot.
bsp-src/linux-6.1/arch/riscv/boot/dts/spacemit/<board>.dts
The dts of the device in the kernel.
bsp-src/linux-6.1/arch/riscv/boot/dts/spacemit/Makefile
The Makefile of the dts of the device in the kernel.
buildroot-ext/configs/spacemit_k1_defconfig
The configuration of buildroot.
buildroot-ext/board/spacemit/k1/env_k1-x.txt
The env of u-boot.
Adding a New Device
If the new device is modified based on DEB1, in order to quickly bring up and verify the functions, it can be modified based on the configuration of DEB1. Usually, only the following configuration files need to be modified:
bsp-src/uboot-2022.10/arch/riscv/dts/k1-x_deb1.dts
bsp-src/linux-6.1/arch/riscv/boot/dts/spacemit/k1-x_deb1.dts
After the bringup and function verification are completed, it is recommended to add a new device to the SDK. For example, to add hs450:
- Using
k1-x_deb1.dtsof u-boot as a template, addbsp-src/uboot-2022.10/arch/riscv/dts/k1_hs450.dts. - Modify

Achieving Adaptive Support through EEPROM

Writing Numbers Using tlv_eeprom
Writing numbers refers to writing information such as product_name into the EEPROM. Currently, the information in the EEPROM is encoded in TLV, and the tlv_eeprom command of u-boot can be used to write numbers.
- Connect the debugging serial port of the device to the PC. When the device starts, press the
skey on the keyboard in the PC serial terminal until entering the u-boot shell.Autoboot in 0 seconds
=> - Burn the
product_name, for example,k1_hs450.=> tlv_eeprom set 0x21 k1_hs450
=> tlv_eeprom write
Programming passed.Programming passed.indicates that the writing is successful. For versions v1.0beta3.1 and later, please name it after the file name of the device dts (without the suffix) to facilitate the automatic loading of the dtb by u-boot. - Use
resetto check if the dtb ofhs450can be loaded. If it is normal, u-boot will have the following print.product_name: k1_deb1
detect dtb_name: k1-x_deb1.dtb
The SDK also supports reading the following information from the EEPROM:
- Serial Number:
0x23 - Base MAC Address:
0x24 - Manufacture Date:
0x25 - Device Version:
0x26 - MAC Addresses:
0x2A - Manufacturer:
0x2B - SDK Version:
0x40Among them, the MAC Address will be updated to the dtb as the physical address of the network card.
Number Writing Tool
Under development.

Since the official u-boot source code does not include our k1-x_bit-brick.dtb, we need to add it ourselves following the steps above. The files that need to be modified are as follows:
