Generally, in upstream CFI flash memory driver uses buffers for write operations. That does not work with AMD chip with id 0x2201 and we must resort to writing word sized chunks only. That is, to not apply general buffer write functionality for this given chip. Without the patch kernel logs will be flooded with entries like below: MTD do_erase_oneblock(): ERASE 0x01fa0000 MTD do_write_buffer(): WRITE 0x01fa0000(0x00001985) MTD do_erase_oneblock(): ERASE 0x01f80000 MTD do_write_buffer(): WRITE 0x01f80000(0x00001985) MTD do_write_buffer_wait(): software timeout, address:0x01f8000a. jffs2: Write clean marker to block at 0x01a60000 failed: -5 MTD do_erase_oneblock(): ERASE 0x01f60000 MTD do_write_buffer(): WRITE 0x01f60000(0x00001985) MTD do_write_buffer_wait(): software timeout, address:0x01f6000a. jffs2: Write clean marker to block at 0x01a40000 failed: -5 References: http://patchwork.ozlabs.org/project/linux-mtd/patch/20210309174859.362060-1-sandberg@mailfence.com/ Signed-off-by: Mauri Sandberg <sandberg@mailfence.com> [added link to usptream fix submission] Signed-off-by: Petr Štetiar <ynezz@true.cz> (cherry picked from commit 8cc0fa8faceadac85353bb1a96e074518ef124e2)
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!
Development
To build your own firmware you need a GNU/Linux, BSD or MacOSX 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.
gcc binutils bzip2 flex python3 perl make find grep diff unzip gawk getopt
subversion libz-dev libc-dev rsync which
Quickstart
-
Run
./scripts/feeds update -a
to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -a
to install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfig
to select your preferred configuration for the toolchain, target system & firmware packages. -
Run
make
to 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.
