Different vendor firmware versions use different BBT table sizes. The
checksum is calculated over the entire table, so the size must match
what the bootloader expects.
The Genexis Platinum-4410 bootloader was compiled with a BBT table
size of 250 entries (MAX_RAW_BAD_BLOCK_SIZE as found in vendor code).
Without this fix, the BBT checksum validation fails:
[ 0.391948] spi-nand spi0.0: Dosilicon SPI NAND was found.
[ 0.397651] spi-nand spi0.0: 128 MiB, block size: 128 KiB, page size: 2048, OOB size: 64
[ 0.407370] en75_bmt: found BMT in block 1023
[ 0.450160] en75_bmt: BBT not found and econet,can-write-factory-bbt is unset, giving up
Add a new DTS property 'econet,bbt-table-size' to configure the BBT
table size. If not specified, defaults to 1000.
After this patch:
[ 0.407021] en75_bmt: found BMT in block 1023
[ 0.449159] en75_bmt: found BBT in block 943
[ 0.453491] en75_bmt: BBT & BMT found
[ 0.457152] en75_bmt: blocks: total: 1024, user: 943, factory_bad: 0, worn: 0 reserve: 81
[ 0.465390] en75_bmt: 117 MiB usable space

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.
Sunshine!
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 python3.7+ 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.
