RT5350启动openwrt无wifi信号，如何解决？

andy_wsj

小弟前几日拿到一个华美MPR-P1，拆开一看是RT5350F的U，决定自己编一个openwrt固件
使用最新版的openwrt，trunk，网上查了一些资料，MPR-A1，MPR-A2都是用RT5350F，正好op支持
于是硬改16Mflash，32M内存，使用op的MPR-A2配置编译
U-boot是官方的版本，我自己增加了16M flash支持
这个板子只有一个网口，编译固件只用openwrt-ramips-rt305x-mpr-a2-squashfs-sysupgrade.bin
rt305x和rt5350配置是同一条选项。
MPR-A2配置是8M+32M，网上有拆机图片

操作：一颗全新flash，先用编程器刷入u-boot，启动后刷入固件openwrt-ramips-rt305x-mpr-a2-squashfs-sysupgrade.bin
问题：刷入启动TTL有打印，可以进入Openwrt，进入后开启wifi重启，无论如何也没有看到wifi信号，网口也连接不上
          进不了设置页面，只有TTL能正常操作。RT5350如何开启wifi？

分析：根据TTL打印
这一段
[    0.520000] 0x000000000000-0x000000030000 : "u-boot"

[    0.580000] 0x000000146297-0x000000800000 : "rootfs"
提到factory这个段，我认为我缺少这个段的数据导致wifi不能启动，如何获得或制作？

以下打印：
[   20.350000] cfg80211:   (2402000 KHz - 2472000 KHz @ 40000 KHz), (N/A, 2000 mBm), (N/A)

信息(N/A, 2000 mBm), (N/A)说明wifi配置数据不正常，我认为可能是0xFFFF，就是没有数据，flash默认的FFFF。

正常的升级是不是：
1、原厂固件升级至openwrt-ramips-rt305x-mpr-a2-squashfs-factory.bin，这时保留factory段
2、openwrt-ramips-rt305x-mpr-a2-squashfs-factory.bin 升级至openwrt-ramips-rt305x-mpr-a2-squashfs-sysupgrade.bin，factory段没有失去。
于是再问，假设我的推理正确，factory段的数据如何从原厂固件读出？或者说如何分辨编程器读出原厂固件的那一段是wifi配置数据？那个固件是ralink官方编译的，厂家修改了界面，没有明确的TTL打印。如果可以确定，我可以使用dd命令将其读出并写入新的固件里面去。

这个问题让我困惑了1周了，上次AR9331也是这样，后来明白了需要一个art文件，自己读出再刷入ART后正常
我就联想RT系列是不是也有一个类似art的文件？

到底是什么原因？我的编译了新固件后wifi就开不了了。

楼主，能说下解决方法吗？

修改下wireless就好了，默认是关闭的

楼主，能说下解决方法吗？

我用最原始的方式：
1、先自己编译了一个u-boot，是128K大小。
2、一片刚刚擦除的16M Flash，然后将128K的u-boot写进去，再用编程器读出来，获得一个16M大小的文件，这个文件里面只有前128k是有数据的，后面全部是空，对于Flash，没有写过的全是0xFF。
3、用编程器，把原厂的Flash芯片固件读出来，根据0x000000040000-0x000000050000 : "factory"这个提示，将读出来的文件偏移量的0x000000040000-0x000000050000 的这一段数据复制到新的16M文件对应相同的地址上。至于怎么读出复制，你可以搜索一下，linux有操作命令，或是windows下使用UE也可以完成修改。
4、保存后得到一个新的16M文件，已经携带Factory这个段了，然后用编程器将16M的Flash芯片刷新，将这个文件烧写进去，这样一个带工厂参数的引导固件就可以使用了。
5、将烧好的芯片与PCB连接，或是焊接回去，上电，通过u-boot烧写Op的固件，启动之后，打开Op的无线开关，buang，无线信号就有了.....

PS: 16M的openwrt固件是我自己编译的，已经改flash支持，4M或8M的芯片操作方式是一样的。你可以试试，祝君成功！

就是没有无线参数，出厂前的无线矫正数据没有，需要手动写入，请参看我给别人的回复

需要先将Factory数据写入固件，再打开wireless才行，直接去打开是没有信号的

自己编译的固件一般factory这步是不用的把，我的直接打开就可以

当使用的插件超过8M的时候，就需要支持16M的固件了
固件内是不包含Factory数据的，但是分区的时候分了这个区，只是里面没有数据而已

你用的是factory的固件把
