【备份贴】一款MT7621 Uboot源码,感觉像H大的不死breed,备份一下

[复制链接]

上一周手残把公司的wayos fbm220g 搞砖了,没有任何备份,在救砖过程中买了TTL+spi flash编程器且google找了很久uboot资料及编译方法,发现一款MT7621 Uboot编译的源码,感觉像H大的不死breed,备份一下

ps:为啥发到小米版块,是因为我家里用小米r3p,好像r3p也是mt7621的cpu

后面发现了这款MT7621的uboot源码:https://github.com/pinney/MT7621-u-boot-mod
我编译过程中遇到过几个问题:
1、编译环境问题:
报错完全看不懂,我先根据教程(https://p3terx.com/archives/build-openwrt-with-docker.html)搭了docker编译lean大的openwrt环境
再模拟编译教程(https://p3terx.com/archives/open ... s-and-commands.html)编译uboot
期间发现一个报错像是bc命令不存在,sudo apt install bc后,能编译uboot了

2、tftp\http上传都报文件超过大小问题: google了一天,发现与问题3是同一个问题,按照教程,打印出jedec后,把chip信息写到源码里再编译就不报错了。
3、uboot 识别不了flash问题:Warning: un-recognized chip ID, please update bootloader!
https://blog.csdn.net/huangkaiyue1/article/details/518113614、但是还是刷不回原厂固件,还没尝试编译Openwrt固件刷机


写得有点乱,目的是自己备份下这些资料,有了这款uboot源码,虽然还没搞成,但感觉离修好不远了。

搞砖了也多半不是Bootloader的问题啊!上编程器有无先备份?至少应该先看看TTL log,否则一步错,步步错

Netgear WNDR3700 v5 专用,DDR2 内存适用

DDR 时钟频率1066也高了点,933只能下修至800

得先知道闪存布局 "/proc/mtd",挑选适合的Breed为本体,再魔改內存頻率參數/DDR 時序參數/串口波特率

官方固件uImage起始于0x4c (2705 1956)

HC5961路由256M nand芯片 512M内存杂交breed的问题?
基于r3g的r3p breed

点评

之前是没有root密码进不去,所以没有备份。。。然后我ttl瞎刷刷砖了。。我再看看你的杂交breed是怎么玩的。。非常感谢指导  详情 回复 发表于 2020-3-18 16:08

我说的是上编程器就先备份,一般来说,u-boot & 固件只会坏其一,不会全坏,重要的还有uboot-env & Factory

刚才看到某网友因疫情严重而失业了,你要保重!别再瞎搞!

看清楚4楼的红字

1. 有无官方固件Bootlog?
2. 为何不刷官方固件而选wndr3700v5?
3. 改动哪些闪存分区?

wayos 的固件flash都不是普通的芯片,写有隐含分区数据的,并且有CRC校验,一般来说只能克隆同款产品数据恢复。

老哥,看了下541G参数好像有戏,太好了,去试试,刚好坛子有人发过固件https://www.right.com.cn/FORUM/thread-168794-1-1.html  详情 回复 发表于 2020-3-19 17:55

@fyi2000 魔改编程器固件,成功救砖! 1、在@bafnczy 的提示下,我在论坛找了一个fbm260w的固件,ttl刷进去后不启动 2、我用编程器导出固件,用winhex与官方升级包进行对比,发现了linux的分区的起始地址为003  详情 回复 发表于 2020-3-20 16:58
