This commit introduces OpenWrt U-Boot all-in-ubi layout support for the CreatLentem CLT-R30B1, enabling: - Fully-featured U-Boot - Effective recovery mechanisms - Prolonged device lifetime by allocating most of the flash to UBI (which takes care of wear-leveling) - Maximum available storage space for OpenWrt - Unified firmware across different device variants OpenWrt U-Boot UBI flash instructions ------------------------------------- Using the installer image ------------------------- To simplify the installation process, this method uses a fork of Daniel Golle's (@dangowrt) UBI Installer https://github.com/dangowrt/owrt-ubi-installer 1. Ensure your router is running the latest generic OpenWrt firmware. Upgrade it if necessary. 2. Obtain the installer image: Build the installer from source https://github.com/andros-ua/owrt-ubi-installer/tree/clt-r30b1 or download a prebuilt image from the https://github.com/andros-ua/owrt-ubi-installer/releases 3. Flash the openwrt*creatlentem_clt-r30b1-ubi-initramfs-recovery-installer.itb image using sysupgrade. 4. Wait for installation: the green status LED will blink rapidly, indicating that the all-in-UBI installer is running. 5. Once the installation finishes, the status LED will turn solid white (lime) for 5 seconds. 6. After the device reboots, perform a final sysupgrade using the openwrt*creatlentem_clt-r30b1-ubi-squashfs-sysupgrade.itb image. Return to stock layout ---------------------- 1. Flash openwrt*creatlentem_clt-r30b1(-112m)-initramfs-kernel.bin via sysupgrade 2. Copy files to /tmp on the device via SCP: BL2.bin u-boot-env.bin Factory.bin FIP.bin openwrt*creatlentem_clt-r30b1(-112m)-squashfs-sysupgrade.bin 3. Restore stock MTD partitions: apk add kmod-mtd-rw insmod mtd-rw i_want_a_brick=1 mtd write /tmp/BL2.bin BL2 mtd write /tmp/u-boot-env.bin u-boot-env mtd write /tmp/Factory.bin Factory mtd write /tmp/FIP.bin FIP 4. Install the system: sysupgrade /tmp/*sysupgrade.bin Recovery -------- Use mtk_uartboot to recover corrupted BL2 or FIP via UART: https://github.com/981213/mtk_uartboot Stock layout ---------------------------------------- | dev: size erasesize name | | mtd0: 00100000 00020000 "BL2" | | mtd1: 00080000 00020000 "u-boot-env" | | mtd2: 00200000 00020000 "Factory" | | mtd3: 00200000 00020000 "FIP" | | mtd4: 07000000 00020000 "ubi" | ---------------------------------------- OpenWrt U-Boot UBI layout ---------------------------------- | dev: size erasesize name | | mtd0: 00100000 00020000 "BL2" | | mtd1: 07f00000 00020000 "ubi" | ---------------------------------- Signed-off-by: Andrii Kuiukoff <andros.ua@gmail.com> Link: https://github.com/openwrt/openwrt/pull/20666 Signed-off-by: Jonas Jelonek <jelonek.jonas@gmail.com>
OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.8+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.
Related Repositories
The main repository uses multiple sub-repositories to manage packages of
different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
