The manufacturer Cudy usually releases signed openwrt firmware, to
facilitate the migration from the proprietary version to the official
versions of openwrt. In contact with the manufacturer tells me that only
releases the firmware of the WR3000H if and only if
there is an official version. With this proposal I pretend to have an
initial operative version so that they do their part, and facilitate to
the users the possibility of using openwrt. In the present state, it is
only possible to use this firmware by uploading and installing it with
UART connection.
AX3000 2.5G Dual Band Wi-Fi 6 Mesh Router (WR3000H)
Hardware
--------
MediaTek MT7981 WiSoC
256MB DDR3 RAM
128MB SPI-NAND (XMC XM25QH128C)
MediaTek MT7981 2x2 DBDC 802.11ax 2T2R (2.4 / 5)
4 LAN MediaTek MT7531 PHY
1 WAN RTL8221B-VB-CG 2.5Gbps PHY (C22)
2 Radios MT7976CN
UART: 115200 8N1 3.3V
MAC:
LAN MAC: label mac
WAN MAC: label mac + 1
2.4G MAC: label mac
5G MAC: label mac + 1 with LA bit set
Installation
------------
1. Connect to the serial port as described in the "Hardware" section.
2. Power on the device + press reset pin. Keep pressing reset pin to
enter the U-Boot shell (The recovery.bin image load process must fail).
3. Download the OpenWrt initramfs image. Place it on an TFTP server
connected to the Cudy LAN ports. Make sure the server is reachable at
192.168.1.88. Rename the image to "cudy3000h.bin"
4. Download and boot the OpenWrt initramfs image.
$ tftpboot 0x46000000 cudy3000h.bin; bootm 0x46000000
5. IMPORTANT: Make backup from original firmware. System -> Backup
/Flash Firmware -> Save mtdblock contents. All mtdblock one by one,
keep unaltered (BL2, u-boot-env, Factory, bdinfo, FIP, and ubi).
6. Transfer the OpenWrt sysupgrade image to the device using scp.
Install with sysupgrade.
Warning for BL2 and U-BOOT developers
-------------------------------------
The nand partition layout from vendor is slightly diferent from "standard".
The FIP partition starts at 0x3c0000 be carefull with BL2 to BL31.
The UBI partition start at 0x5c0000 be carefull.
DO NOT OVERWRITE bdinfo partition it contains hardware MAC definition
Layout is start-end (not start size)
- 0x000000000000-0x000007800000 : "nmbm0"
- 0x000000000000-0x000000100000 : "bl2"
- 0x000000100000-0x000000180000 : "u-boot-env"
- 0x000000180000-0x000000380000 : "factory"
- 0x000000380000-0x0000003c0000 : "bdinfo"
- 0x0000003c0000-0x0000005c0000 : "fip"
- 0x0000005c0000-0x0000045c0000 : "ubi"
ALLWAYS for U-BOOT operations check this
setenv mtdids nmbm0=nmbm0
setenv mtdparts nmbm0:1024k(bl2),512k(u-boot-env),2048k(factory),256k(bdinfo),2048k(fip),65536k(ubi)

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.
