Avalon is the first product name of Avalon project. Avalon is a project which produces [[bitcoin]]  ASIC<ref>https://en.wikipedia.org/wiki/ASIC</ref> mining machine. the project created by 张楠赓<ref>http://www.canaan-creative.com</ref> <ref>https://bitcointalk.org/index.php?action=profile;u=38132</ref> and Yifu Guo<ref>http://bitsyn.com</ref> <ref>https://bitcointalk.org/index.php?action=profile;u=68196</ref>. this project started at later 2012 with a bitcointalk<ref>https://bitcointalk.org/</ref> thread<ref>https://bitcointalk.org/index.php?topic=110090.0</ref>. Avalon project have three different ASIC, named A3256, A3255, A3233, have two type of bitcoin transaction machines. Avalon1 and Avalon2. right now Avalon project people working very hard on third generation machine. named Avalon3. it is 2U size, using the newest 40nm ASIC, (7GHS/chip, 0.7Watt/G).

== FT232焊接不良 ==
|valign="TOP" style="background:#D4EDFB;border-left:5px solid white;border-right:5px solid white;border-bottom:5px solid white;" |
FT232的QFN焊接不良，存在假焊或者虚焊的现象，测试的时候正常，运输震动以后焊点脱开导致问题。维修方法：拆下FT232芯片，清理焊盘和芯片再重新焊上去就可以了，100%能修好。

== 红灯 ==
|}
红灯的意思是电源故障。这里有很多可能，所以这样看：
# 确定电源没有故障。部分质量差的电源无法正常工作就会红灯。
# 确定电源连接线没有松动。
# 观察模组是否有烧坏或者碰掉的元器件，必要时可用排除法，逐个模组上电检查。在确定故障模组以后可以先拆下这个模组维修，其他模组可以照常运行。


== 冒烟 ==


冒烟情况比较多，常见于电容C1和Project字样下方的4颗电容。
= Where to Buy =
这是由于这几颗电容本身负载比较重，而且超频以后电流大幅度提高造成的。现在建议有烧坏的模组就拆下不要使用，因为电容损坏以后会发生短路，会导致电源保护（红灯）以及。如果尚有维修价值的话，可以更换这几个电容。C1的型号为680uF/2.5V 钽聚合物电容，但是可以不安装。而Project下面的那4个电容从左到右是4.7uF/16V/0805, 22uF/16V/1210, 22uF/16V/1210, 4.7uF/16V/0805. 材质是X5R或者X7R，直接更换就可以。

如果是板子的一些没有元器件的地方冒烟，那么可能是PCB背面的防护层被划破与地短路。这种情况比较难以维修。

== 开机连不上192.168.0.100 ==
= References =
=== 蓝灯不亮 ===
<references/>
这是因为机器内部的703N损坏，或者USB线缆脱开造成的。需要检查USB线缆的连接。检查短路电阻J1。如果还不亮就是坏了。换一个703。


=== 重置703N ===
[[zh-cn:阿瓦隆]]
# 按住Reset接通电源
# 蓝灯闪的时候松开Reset
# 蓝灯现在快速闪烁
# 现在配置笔记本电脑IP为 192.168.1.2
# 在笔记本上运行  telnet 192.168.1.1，登录之后运行以下命令：
  a. mount_root
  b. rm -rf /overlay/*
  c. reboot
这样703n恢复到初始状态，需要再刷一次配置文件。现在可以访问 192.168.0.100 更新配置文件


== 运行一段时间以后断网 ==
[[Category:Hardware]]
这个原因往往是703的温度稳定性差，在温度上升以后就不能稳定工作。需要加强703的散热。
 
 
== 模组不能工作 ==
判断方法是在log里面看到有模组输出是0。对于2模组来说，后8个是0这是正常的。
如果有不正常的0，需要检查灰排线的连接情况，一般来说是由于运输震动造成的线缆脱开造成的。
