uboot mod for Huawei B5328 about u-boot_mod HOT 10 CLOSED

i was able to make a connection using serial port with rx tx and gnd now i was able to printenv but i am unable to ping to pc using address 192.168.0.10 which i set manually .
is it because the current env variable ethact=mii0
gatewayip=192.168.0.1
netmask=255.255.255.0
ipaddr=192.168.0.1
serverip=192.168.0.10
ethact=mii0
pesifwcheck=1

here is the output of the command printenv :

i deleted from telnet the partition of the kernel so the device is not able to load the kernel but i have a nand dump of each partition already made before on a working one .
now my question is how can i perform a backup of that partition using uboot ?

thanks for help

uboot version is 2010

Thanks for your reply i'll close the ticket , i'd expected some help from your side but thanks ...

@coolirc This is just not the correct place, because this project has nothing to do with Huawei U-Boot and opening an issue in a different software project is not the correct way to ask for help. We don't know anything about Huawei-U-Boots and especially I don't know what you want to achieve. If you want to get a dump of the partitions, try to read it out directly. If that doesn't work, write a script that abuses the md command.

"We"? Why are you speaking on my behalf? This is not your repository and not your project, so next time please be nice for others and speak only on your behalf.

Cheers,

Understood, but "we" was meant as people having to do with ath79 U-Boot. If you ask about motor issues with your yacht in a sports sailboat forum, I guess sailors would refer to themselves as "we", too. And I think it's also not nice to bug people opening an issue/bug report asking for help for a unrelated thing like in a forum.

well i'm not totally out of subject like you say , i was hoping to port uboot to that board since it's a new chip and since that repository was named U-boot_Mod so it's actually being in the subject .

@coolirc Ah okay... This U-Boot-Mod is for special WLAN routers with Qualcomm/Atheros chipsets. Your Huawei has a Realtek chipset and as you were already told in OpenWrt forum, chances are bad for easily supporting this device without source-code or proper specifications.

Write an email to Huawei and ask them where to find the source code and if they don't have it available e.g. on the accompanying CD or on the internet, tell them they need to release the source-code as it's a GPL violation otherwise. This also includes the U-Boot source code (while I doubt that you need a custom U-Boot at all).

Personally I think this device is not worth the effort for trying to write a custom U-Boot or even supporting it in OpenWrt, because it is overpriced. I recommend you to sell it on eBay before it's getting completely outdated and worthless. I have bought a Huawei 4G router 2 years ago for $150 which at that moment costed more than $400 on eBay. Now it sells for under $30.

@coolirc That's only the source code for the SoC. Please ask in the OpenWrt forum for help.
