-Supported under the OpenWrt target ''​au1000''​ https://​dev.openwrt.org/​wiki/​au1000 +{{:​media:​toh:​meshcube_klar_freigestellt.jpg}} 
-Supported ​since OpenWrt Kamikaze.+ 
 +The "​MeshCube"​ (MTX-1) was one of the first extensible Wireless hardware built with "mesh routing"​ and community support in mind.  "​AccessCube"​ was the commercial marketing term for exactly the same hardware. Later a "​singleboard"​ variant was sold by T-Systems as "​Internet Box". Allthough the HW is not produced any more, a few "​cubes"​ keep running in community networks, especially Berlin. ​Supported ​since OpenWrt Kamikaze ​under the OpenWrt target ''​au1000''​ https://​dev.openwrt.org/​wiki/​au1000

 + 
 +==== Installation using the TFTP method ==== 
 + 
 +See [[doc:​howto:​generic.flashing.tftp]]. 
 + 
 +We need a TFTP Server on a PC. On the MeshCube you connect the Serial port, and enter YAMON bootloader. First we need to erase the flash: 
 + 
 +<​code>​ 
 +YAMON> setenv ipaddr FREE_IP.IN.YOUR.NET 
 +YAMON> setenv bootserver IP.OF.YOUR.TFTP_SERVER 
 +YAMON> erase 0xbfd00000 0xf0000 
 +YAMON> erase -s 
 +</​code>​ 
 + 
 +Then we can load the kernel and filesystem:​ 
 + 
 +<​code>​ 
 +load /​openwrt-au1000-au1500-vmlinux-flash.srec 
 +load /​openwrt-au1000-au1500-jffs2-128k.srec 
 +</​code>​ 
 + 
 + 
 +==== Serial and JTAG ==== 
 + 
 +The MeshCube has a Serial and JTAG connector at the front, just above the power plug. See 
 +-> [[doc:​hardware:​port.serial]] and -> [[doc:​hardware:​port.jtag]] for general information about the JTAG/serial port, cables, etc. 
 + 
 +The following serial port settings are used: 
 + 
 +| bps   | 115200 | 
 +| data bits   | 8    | 
 +| parity  ​ | None   | 
 +| stop bits   | 1    | 
 +| HW flow control | no     | 
 +| SW flow control | no     | 
 + 
 +The Serial/JTAG Port has the following pin-out, as seen from the front: 
 + 
 +| 02 | 04 | 06 | 08 | 10 | 12 | 
 +| 01 | 03 | 05 | 07 | 09 | 11 | 
 + 
 +The pins are assigned like this: 
 + 
 +| 01 | TXD (3.3v) | Serial | 
 +| 02 | RXD (3.3v) | Serial | 
 +| 03 | VCC (3.3v) | | 
 +| 04 | TCK   | EJTAG | 
 +| 05 | RST#   | EJTAG | 
 +| 06 | TMS   | EJTAG | 
 +| 07 | DINT   | EJTAG | 
 +| 08 | TDO   | EJTAG | 
 +| 09 | GND        | | 
 +| 10 | TDI   | EJTAG | 
 +| 11 | GND        | | 
 +| 12 | TRST   | EJTAG | 
 + 
 + 
 +The "​T-Mobile Internet Box" has a connector close to the Ethernet port with the following pinout: 
 + 
 +| 1: GND | 2 | 
 +| 3 | 4 | 
 +| 5 | 6 | 
 +| 7 | 8 | 
 +| 9: RX | 10: TX |
