Editing firmware is not a problem once we know what to edit. Problem will be putting the modified .hex back to .ar file, that's where we will have...
Nothing, read the post above, I just downgraded to version 1.09B and telnet works there.
Ok, made it working :) Now my printer also goes into diag telnet, I wonder if there are any commands we can use :)
Great find! I was trying the same credentials on 1.14B and it did not work. Strange, I thought credentials are not correct for the diag telnet....
Oh, I see you are having fun! That's great! :) By the way, who can tell me, where are cartridge chip readers connected?, Also, what is connected...
@eychei, @Geezer70 My pleasure, send me PMs with your e-mails plz.
It can. PIC32 is MIPS, little endian, you also need to create proper memory segments. I have IDA files if you need them.
I have seen this too. 3d/print3d do not work for me either with telnet. I have seen the contents of ftp.cubify.com, you can find user/pass for it...
I did find it too :) Waiting for my programmer for arrive so I can try to do some tracing as well. Digging through PIC32 assembly is quite hard...
Yep. If you're on Linux/Unix/Mac, dd command will do as well
I'm looking for byte-by-byte copy of the SD card (image), not just copy of the files on it. Not sure about the extension cable... haven't seen...
I surely will, so far not much to share, digging through the firmware itself, successfully loaded it to IDA, but I don't understand the logic yet....
I'm just doing some reverse engineering on the firmware. The contents of the SD would be helpful.
Any will do, but latest (1.14 if I'm not mistaken) will be better
Guys, if somebody was doing the reverse engineering of the printer, can somebody please send me the contents of the SD card? I would really...
