Dump of Quantenna's NVRAM on RT-AC87U

[Oleksiy Lukyanchykov]

Hi all,

I'm trying to reflash accidentally erased NVRAM of Quantenna SoC by an universal programmer. I guess that I have to concatenate dumps from all /dev/mtd* partitions on Quantenna SoC into the single file and write that file into the NVRAM chip. Can anyone share dumps for all mtd partitions of Quantenna SoC?

Thank you in advance!

There's no NVRAM inside QTN.

Exactly what you have done in detail?

If you erased the CFE / Bootloader you can always recover it with your programmer, JTAG will not work on that model, no software support at this moment.

As long as you didn't zero out the boot-loader - a reflash/reset of the factory firmware should put you back in business...

@hggomes - Exactly in your source code - what have you done in detail - I still have a pending GPL pull request...

Sounds like you nuked the Quantenna stuff then...

So it's the reason why I'm asking for dumps of /dev/mtd* for Quantenna SoC.

 

[hggomes]

mtd1 = uboot_env, better forget it...

Flash the TSOP again or just RMA it (easy way).

 

[Oleksiy Lukyanchykov]

I'd like to reflash. So I need data which will be flashed, right? And I've asked for data in the first message, isn't it?

 

[hggomes]

Yes, you need the QTN data from RT-AC87U, why not RMA? Out of warranty already?

 

[Oleksiy Lukyanchykov]

I've bought RT-AC87U in US, but I'm in Ukraine now. Asus doesn't provide worldwide guarantee. So it's more easily and funny to recover the router by myself. And yes, it's out of warranty already.

 

[hggomes]

Good luck.

 

[Oleksiy Lukyanchykov]

Thank you! I need dumps more than luck now

 

[hggomes]

Indeed, but think it could be worse, at least you have the router working and with 2.4GHZ.

sfx2000, this is getting really old.

I get the need for gpl compliancy, but this is just public harassment at this point. Please PM hggomes directly instead.

@sfx2000 i agree with @L&LD U should talk on pm. Cheers

Guys, it's not so complex to dump /dev/mtd* partitions of Quantenna. Quantenna also runs Linux, so you just need to execute "dump" command few times and copy results. Type "telnet 1.1.1.2" in RT-AC87 command line to log into Quantenna.
Thanks for your help in advance!

Doesn't seem to work on mine.

admin@RT-AC87U:/tmp/home/root# telnet 1.1.1.2
telnet: can't connect to remote host (1.1.1.2): Connection timed out

Same here..
