VIM3 ubuntu 5.5和manjaro安装后显示器偏色,如何擦除emmc?

我在sd卡上安装了VIM3 ubuntu 5.5和manjaro,但启动后显示器严重偏色,如何擦除emmc?

@fatpig 你好,我们docs上面有相关的文档

请参考这个

我试过您提的方法了,可惜无效。我不但试过您回复的方法,我还试了https://docs.khadas.com/zh-cn/vim3/HowtoEraseEMMC.html,讲的“命令行模式”,也无效。我已经在emmc里装了linux 4.9,官方的image,所以用dd命令覆盖了/dev/bootloader的内容,而且我还把覆盖以后的/dev/bootloader的内容hexdump出来,确认是全0,可是重启无论是进入ubuntu 5.5,还是manjaro官方对VIM3的版本,和改写bootloader以前完全一样,还是严重的偏绿,没法看。

Hello, I will use Google translate to help you.

这将解决emmc启动时的绿色问题。
接下来,如果您想使用SD卡中的manjaro映像,则需要确保您在emmc上具有兼容的uboot

希望这可以帮助

@fatpig 麻烦确认一下清除是否成功了,你拔掉SD卡,上电,看到这个才是清除成功了

thanks a lot. I will try it tonight.

怎样才能看到您输的那串东西,启动过程一闪就过啊…
您是要我插上232线,从tty登录吗?
我确认emmc的/dev/bootloader里的内容已经被清零了。
我从emmc的ubuntu 4.9启动登录后,运行一下命令:
dd if=/dev/bootloader of=./abc
hexdump ./abc > abc.txt
cat abc.txt
abc.txt里的内容全部为0
但是结果仍然绿屏

@fatpig 需要从串口看的,如果清理了EMMC,拔出SD卡,串口只会输出这一行,不会闪过的

谢谢,可是手上没232的线,只能等我去弄条来再试试。

@fatpig 串口是 USBtoTTL 的

您的意思是如果请掉了emmc,拔掉了sd卡,vim3是不能启动的吗?

thank you ,usbtoTTL 这个我知道。

@fatpig 是的,无法启动,然后串口打印那一串信息

@fatpig 你好,你解决了么 , 能正常启动了么

不好意思,在淘宝订了条线,没那么快到,我也挺着急。

Thx, it works. I install Manjaro xfe in my VIM3 emmc in your way first and boot up Manjaro plasma installed on sd card before, then everything’s fine. This image downloaded from manjaro.org. So I think the uboot is match, maybe I can just install the new uboot rescue into emmc, I’ll try it late. Thank you.

u can install manjaro or ubuntu via Krescue
this images already available

PS: u can preload this image or use krescue online installation - just plug sd card and Ethernet cable to your vim device

Thx.Rescue is good way to setup vim. I have try it.But unfortranately, Manjaro.linux.xcfe can not boot up after update it.

I will test this. It should run just fine until there was any changes made up the boot partitions.
Also it can be due to the new structure we have been following from latest releases.
