MW4530慎刷OpenWrt

679***

昨天刚到4530，刷写了4310的openwrt固件，结果发现无法启动
后又合成了4310，4300的编程器固件写入，均能正常启动
仔细分析op日志，发现是4530用了m25Q64闪存，而官方openwrt是没有这个驱动的
下面附上ttl，红色部分即为出错信息，暂时没编译环境
有兴趣的可以试下修改
drivers/mtd/devices/m25p80.c
增加箭头所示内容重新编译

我买了三个，打算给公司用，早知道就买tp了，悲剧啊。上 flash图

ad***

自己换掉啊。。。。。我还特地买了两个8m flash 和两个16m flash  mx的

不过我倒是没有你这问题   我是最早刚出的时候买的  刷入正常使用

满***

看来早买早省心啊

每个厂家Flash的ID好像不同.

关注一下。

看来新版的换了

请问你买的16m的flash是神马型号的？

遗***

那怎么办？等新的op固件还是没救了，除了换flash

提交patch是根本解决办法，估计淘宝换卖flash的厂家又该涨价了

msx***

硬件版本v2了？看来缩水了
