There are two hardware revisions. The revision is in the bottom label:

- R01: only with backfire 10.03.1. Fixed in R35352.

- R01A: all versions.

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.

• ADSL modem is working with Annex A.
• FXS works and can be used with Asterisk or danube-voip.
• USB works.
• WIFI works in trunk since R34939 and in AA since R36510

Note: When using integrated ADSL the SoC runs very hot, so would be a good idea to replace the heatsink, while working only as a router the heat emission is low.

1. → obtain.firmware
2. → Install OpenWrt (generic explanation)

Please check out the article Flash Layout. It contains an example and a couple of explanations.
