Andreas Böhler 9ee6ac00c4 ramips: Add support for SERCOMM NA502S 
The SERCOMM NA502s is a smart home gateway manufactured by SERCOMM and sold
under different brands (among others, A1 Telekom Austria SmartHome Premium
Gateway). It has multi-protocol radio support in addition to LAN and WiFi.

Note: BLE and audio are currently unsupported.

Specifications
--------------

  - MT7621ST 880MHz, Single-Core, Dual-Thread
  - MT7603EN 2.4GHz WiFi
  - MT7662EN 5GHz WiFi + BLE
  - 128MiB NAND
  - 256MiB DDR3 RAM
  - SD3503 ZWave Controller
  - EM357 Zigbee Coordinator
  - Telit UMTS module
  - Rechargeable battery
  - speaker and microphone

MAC address assignment
----------------------

LAN MAC is read from the config partition, WiFi 2.4GHz is LAN+2 and matches
the OEM firmware. WiFi 5GHz with LAN+1 is an educated guess since the
OEM firmware does not enable 5GHz WiFi.

Installation
------------
Attach serial console, then boot the initramfs image via TFTP.
Once inside OpenWrt, run sysupgrade -n with the sysupgrade file.

Attention: The device has a dual-firmware design. We overwrite kernel2,
since kernel1 contains an automatic recovery image.

If you get NAND ECC errors and are stuck with bad eraseblocks, try to
erase the mtd partition first with

mtd unlock ubi
mtd erase ubi

This should only be needed once.

OpenWrt logo

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.

binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.6+ rsync subversion unzip which

Quickstart

  1. Run ./scripts/feeds update -a to obtain all the latest package definitions defined in feeds.conf / feeds.conf.default

  2. Run ./scripts/feeds install -a to install symlinks for all obtained packages into package/feeds/

  3. Run make menuconfig to select your preferred configuration for the toolchain, target system & firmware packages.

  4. 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.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
