 +====== Arcadyan ARV4518PW (SMC-7908-ISP) ======
 +
 +===== Known Supported Versions =====
 +^ OpenWrt Versions Supported ^^^
 +| Backfire 10.03.1 | Attitude adjustment 12.09 | Barrier Breaker 14.07 |
 +
 +There are two hardware revisions. The revision is in the bottom label:
 +
 +  * R01: Backfire 10.03.1, but without wifi. Doesn'​t work with Attitude Adjustment because nobody tested the patches. Full support since [[https://​dev.openwrt.org/​changeset/​35352|R35352]].
 +  * R01A: Since Backfire 10.03.1.
 +
 +Although the boards seems to be identical, the R01A has a 33 MHz independent crystal for the PCI bus clock in the back side of the board, while the R01 uses the Danube 33MHz internal clock as blogic noted.
 +
 +===== Hardware Highlights =====
 +^ CPU                          ^ Ram    ^ Flash   ^ Network ​  ^ USB   ^ Serial ​  ^ UART   ^
 +| Lantiq Xway Danube @333Mhz ​  | 64MB   | 4MB     | 4 Ports   | 1x    | Yes      | ?      |
 +
 +
 +==== Openwrt status ====
 +  * ADSL modem is working with Annex A.
 +  * FXS works and can be used with Asterisk or [[http://​code.google.com/​p/​danube-voip/​|danube-voip]].
 +  * USB works.
 +  * WIFI works in trunk since [[https://​dev.openwrt.org/​changeset/​34939/​trunk|R34939]] and in AA since [[https://​dev.openwrt.org/​changeset/​36510/​|R36510]]
 +
 +Note: When using integrated ADSL the SoC runs very hot, so would be a good idea to replace the stock heatsink to avoid issues, while working only as a router the heat emission is low.
 +
 +===== Installation =====
 +  - -> [[doc:​howto:​obtain.firmware]]
 +  - -> [[doc:​howto:​generic.flashing|Install OpenWrt (generic explanation)]]
 +
 +==== Flash Layout ====
 +Please check out the article [[doc/​techref/​flash.layout|The OpenWrt Flash Layout]]. It contains an example and a couple of explanations.

 +
 +  * Recommended to make a backup of the whole flash before starting, specially the "boot params"​ partition as it has the calibration info for wireless to work and the base MAC addres.
 +  * This device comes from factory with [[doc:​techref:​bootloader:​brnboot]] as bootloader. It can be used to load u-boot via uart and the xmodem protocol to ram, as a second stage bootloader.
 +  * Use target Lantiq GPON/XWAY, subtarget Danube, target profile ARV4518PWR01 or ARV4518PWR01A.

 +==== Serial Port ====
 +  * Serial port is at 3.3v and the bitrate is 115200.
 +  * Going horizontally from the marked pin (1): 2:RX, 3:TX, 5:GND, ( 6.+3.3v No need to plug this one).\\ {{:​media:​arcadyan:​danube_serial.png?​200|}}
 +  ​
 +==== U-Boot images ====
 +  * uboot-lantiq-arv4518PW_brnboot meant to be loaded from brnboot as a 2nd stage bootloader, on memory.
 +  * uboot-lantiq-arv4518PW_flash meant to be flashed into the unit as the main bootloader, at 0xB0000000-0xB000FFFF.
 +  * uboot-lantiq-arv4518PW_ramboot meant to be uploaded via UART by the cpu if flash'​s bootloader is broken, for rescue purposes.
 +  * If kernel ignores parameters from u-boot, remove the preceding - in linux'​s hardcoded cmdline. ​
 +
 +
 +==== UART boot ====
 +To enable UART booting in the ARV4518 board, just shortcut R80 and put the left side of R65 to +3.3V and…
 +
 +<​code>​ROM VER: 1.0.3
 +CFG 04
 +Read EEPROMX
 +X
 +UART</​code>​
 +
 +**Done!**
 +
 +  * Then upload the uboot.asc version from uboot-lantiq-arv4518PW_ramboot.
 +
 +==== SPI ====
 +**[[wp>​Serial_Peripheral_Interface_Bus|Serial Peripheral Interface]]** ​
 +
 +The Lantiq Danube has a SPI interface. In some boards it is used to drive a SI3050, while in others like the ARV4518PW only the solder pads are present, so could be a chance to attach a SPI device to the board. In this board the possible location of the SPI pads is in U41.
 +
 +The SPI interface signals should be the same that there are in the Huawei [[ toh:​huawei:​hg556a#​spi|HG556 ]]
 +
 +This is still work in progress.
 +
 +=====TODO=====
 +  * Enable vlan support as default, like in some other boards.[[https://​dev.openwrt.org/​browser/​branches/​attitude_adjustment/​target/​linux/​lantiq/​base-files/​etc/​uci-defaults/​network|UCI Defaults]]
 +  * Add support for hardware revision R01 in Attitude Adjustment. Possible [[http://​www.mediafire.com/?​7csza44e5xcyocg|patch]].
