Refer to Section 6.1.1 of the document `EBC77_Series_Single_Board_Computer_UG_EN.pdf` in documents directory. ### Ubuntu image burning Insert SD Card into EBC7700 then enter the following command (it might takes 20 minutes depends on SD card performance) ``` => es_fs write usb 0 sbc-ubuntu-24.04-preinstalled-server-riscv64_20251211_0111_41.img mmc 0 => reset ``` Demo output ``` => es_fs write usb 0 sbc-ubuntu-24.04-preinstalled-server-riscv64_20251211_0111_41.img mmc 0 Write progress: 87%:+++++++++++++++++++++++++++++++++++++++++++ ``` ### Essdk deb packeges install If you find that installing essdk deb packages using `apt install` is too slow, you can download the essdk and ffmpeg deb packages from essdk_ffmpeg_251030.zip [here](https://github.com/eswincomputing/ebc7700-sbc-ubuntu/releases/tag/2025.10.30) and install them by `dpkg -i XXXX.deb`. ## Download from network disk If you are unable to download images from GitHub and you are in China, you can try downloading them [here](https://pan.baidu.com/s/1Gb-byFiH3-IZeW0jE2lckQ?pwd=2xti). ## Login to the board Using Serial Console Default username and password for ubuntu image is `ubuntu`. On first boot, user will be prompted to change the default password. ## FAQ **Q**: How to burn or update software? **A**: Please refer to EBC77 Series Single Board Computer User Guide Chapter 6 Burn program, the section provides a detailed introduction to the installation and update of Bootloader and Ubuntu system images. --- **Q**: How to switch from HDMI to MIPI DSI output? **A**: Follow the steps below: Firstly, when the power is disconnected, you need to connect the raspberry 7-inch screen with the MIPI DSI interface. After startup, log in to the ubuntu system. Refer to the following command to modify the dtb files that the ubuntu system depends on. After completing the command and restarting, you can use the MIPI DSI interface to output. ``` sudo su cp /lib/firmware/6.6.92-2025-eic7700/device-tree/eswin/eic7700-sbc-a1-mipi.dtb /boot/dtbs/6.6.92-2025-eic7700/eswin/ ln -sf /boot/dtbs/6.6.92-2025-eic7700/eswin/eic7700-sbc-a1-mipi.dtb /boot/dtb-6.6.92-2025-eic7700 reboot ``` In addition, if you want to switch back to HDMI, the user needs to operate the following command and then restart. ``` sudo su ln -sf /boot/dtbs/6.6.92-2025-eic7700/eswin/eic7700-sbc-a1.dtb /boot/dtb-6.6.92-2025-eic7700 reboot ``` --- **Q**: Which models of sd cards are recommended for loading system images? **A**: The following models of sd cards have been verified to be compatible with the EBC77 Series Single Board Computer. - SanDisk Ultra 32GB A1 - SanDisk Ultra 64GB A1 - SanDisk Ultra 256GB A1 - Kingston SDCS2/64GB A1 - Kingston SDCS2/256GB A1 --- **Q**: How to use 2lanes camera? **A**: At present, need to change the dts and compile kernel. Follow the below steps to config 2lanes imx219 dts: - find the eic7700-sbc-a1-camera-imx219.dtsi - change property phy_mode=<5> under vi_subsys node - change property num_lanes = <2> under mipi_csi2_x node - change properties lanes = <1 2> and lanes-dp-dn = <0 0> under csi2_dphy_hw node - change properties data-lanes = <1 2> and link-frequencies = <456000000> under imx219_x node You can adapt other sensors based on this imx219 dts.
