export host-name=<Your HOST name>

This command needs to be run every time you enter the shell, or you can add it to /etc/profile to run automatically every time you enter the shell

Hi, I tried to enter this command in the console. I get the error export: host-name: bad vatiable name. I tried to add this command to the end of the file /etc/profile after rebooting I could not log in to the system and the client information did not appear on the dhcp server. There is an unnamed client. How can I solve this problem? There is definitely no option to add something to buildroot?

I'm sorry, I forgot the naming convention. You can't use minus signs “-”. You have to use underscores “_” instead.

Hello. Thank you, now everything is built in buildroot as needed, the hostname $(hostname) line itself has been added to interfaces. But I ran into another problem. I want to use OLED 0.96 128*64 i2c in the project. And for this screen I need to install pip3 install adafruit-circuitpython-ssd1306 during the installation the system tries to build sysv-ipc . But it runs into an error: it cannot find the gcc build environment because it cannot be on the board system, it refers to luckfox-pico/sysdrv/source/buildroot/buildroot-2023.02.6/output/host/bin/arm-rockchip830-linux-uclibcgnueabihf-gcc
I'm trying to build using this material https://github.com/tohfaakib/OLED_Stats

How can I build sysv-ipc? It will probably not be possible to install gcc on the board; there is not enough space on the FLASH.

Luckfox pico is not a multi-core single-board computer like Raspberry Pi. As a simple and low-cost embedded device, its own resources are limited. After installing gcc, it not only takes up a lot of storage space, but also cannot run due to insufficient memory when compiling large projects. It is recommended to use cross-compilation tools on PC for all compilation work.

Hello. I have a question about the SD card. The Ubuntu system is written using the SocToolKit utility. I have made some settings. And I want to make a backup copy. But the problem is that my card is 128 GB. How can I make a backup copy of only the contents and not the entire volume of the card? That is, I need a small image to then write it to any card.

At present, the solution of packaging the image from the board is still under development, and the only way to build the burning image is in the compilation stage
