Arris TG2492 (VM Super hub 3)

[danman]

i have another board, from a 1602A arris . how can i trace or find the corresponding pins ?

Do you have an oscilloscope or a logic analyzer?

Something like this:
$ mkdir /tmp/mmc;chmod 777 /tmp/mmc
$ sudo in.tftpd -cls /tmp/mmc
$ ssh root2@192.168.0.1 /bin/bash -i
root2@192.168.0.1's password:
/bin/bash: can't access tty; job control turned off
# cd /dev
# for p in mmc*;do tftp -p -l $p 192.168.0.100;done

I'm getting PMs about how did I extract the FW. It's easy, you need a "better" SD card reader, in my case Transcend TS-RDF5K, SD or microSD breakout board:

and connect corresponding pins on the board:

Then you just insert the breakout board, connect pins to your board and you can extract.

Can i pm you?

Why not ask here?

i will have to buy either or so i can test each point signals? to know which one are the clk , cmd, dat0, dat1. dat2?

show the other side right under the NAND, there should be an eMMC controller.

will this help me find the pins. 

what about d0, d1, d2?

It's irrelevant if you don't have a scope.
