Title: router firmware reverse engineering - need help
Post by: pant3k on November 04, 2019, 12:12:23 pm

Hello,
I'm trying to see what's inside DI-524 firmware.
CPU RDC2600 also know as AMRISC 10100(probably x86 arch).
Binwalk found nothing usefull. File doesn't have any common compression.
Jtag doesn't work(probably somehow disabled) tdo with 0V(got 3.3 when firmware is crashed, but it doesn't help anyway).
Dumped full flash with TL866II Plus in radare2:
type bios
class 1.0
arch x86
bits 16
machine pc
endian little
....
....
type bios
arch pc
bits 16
endian little

Any hints?

Post a link to a firmware dump and someone may take a look at it.

Doesn't look compressed, what are you looking for?

Only some files are in plain. I need firmware assembler code, system files etc.
