Analyze flash dump of NX

Post by Go4IT »

Hey guys, after reading out and browsing through the contents of the mainboard Flash, i found lot's of interesting readable strings there. Maybe it tells uns more about the architecture of the system.

The flash is only partially used. An image representation of the contents i made with https://binvis.io gives an good overview:
NX_7S7T-18K931-BL_NX_7612300534_MBFLASH.png
The white areas are unused (0xFF, which means "blank" in the terms of a Flash memory).

You can also find compile dump sessions of the source code over and over, very informative. Also many references to debug messages. I wonder if we can get them somewhere on the UART ports. Shure, only with some magic telling the system to,put them out (switch into debug mode). But it could also that these are only library messages, not being triggered or used in the production code. Here is an example:

So they are used "tcc" to compile, er? ;-) Now it's clear the software is written in C/C++ on the base of an Nucleus RTOS. Also there is no doubt about the processor architecture "--cpu=ARM926EJ-S". Oh, i really want to get my hands on this "d:" drive ;-))

I also hope to find a filesystem or other datastructures somewhere. I've added a "strings only" version here,to download so you can look into it, even if you are not able to dump a flash yourself. Also added two extracted versions only containing the Windows- and Linux-Style paths. Those are "uniqed", so remove duplicate lines.

Also added an output of "binwalk". Just a trial to identify what's inside the Flash. It did not find any filesystem at all, but this ELF:
"0x140020 ELF, 32-bit LSB executable, ARM, version 1 (SYSV)"
The results of "readelf" is added too.

Let's do some "buzzword bingo" and analyze the meaning of some lines and terms found in the hexdump:

Code: Select all

--cpu=ARM926EJ-S
This is what we are dealing with. Helpfull and needed for disassembling the code. As you can read here https://en.wikipedia.org/wiki/ARM9 The ARM926EJ-S processor family was first introduced 2001. As you can find here https://en.wikipedia.org/wiki/List_of_A ... hitectures, the "ARM926EJ-S" core belongs to the "ARM9E" family and uses the "ARMv5TEJ" architecture (instruction set). The only thing we should worry about is this: "ARM926EJ-S with ARM Jazelle technology, which enables the direct execution of 8-bit Java bytecode in hardware, and an MMU". Hopefully, the engineers void using Java :|

ARM/Thumb C/C++ Compiler, RVCT2.1"[/b]
They use "tcc", which is the C-compiler of the "RealView Development Suite". Looking at [url]http://infocenter.arm.com/[/url] a real good site for all ARM related infos, if found "RVCT" stands for "RealView Compilation Tools". It generates code for the 32-bit ARM and 16-bit Thumb and Thumb-2 instruction sets and support full ISO standard C and C++.
Some usefull documents i found for later use:

Some quick notes about "Thumb" instruction set: "Processors since the ARM7TDMI have featured the Thumb instruction set. When in this state, the processor executes the Thumb instruction set, a compact 16-bit encoding for a subset of the ARM instruction set." - I don't expect to find any Thumb code in the NX, because space is no matter here.

Re: Analyze flash dump of NX

Post by Go4IT »

I made a new discovery. It seems the Flash contents gets modified by the system itself, without doing any updates. Maybe from the view of the operating system (RTOS) the Flash is like a filesystem, where it can read and write to some parts of it (e.g. a /var or /tmp location).

After flashing an image to an faulty NX and immediatly after flash, read it back, i found differences, which i did not expect to be. AS an example, the original Flash at address 0x3de96a0 looks like this:

Code: Select all

03DE96A0  31 37 38 2C 20 66 69 6C 65 6E 75 6D 20 31 30 00  178, filenum 10.
03DE96B0  FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
03DE96C0  FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
03DE96D0  FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
03DE96E0  FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF  ÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿÿ
...
where after flashing it looks like this:

Code: Select all

Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F

...
As you can see the last equal part is the textline "178, filenum 10.", which is correctly terminated by an 0x00 (c-string representation).
After the flash the system places more information after this one, and for me, it looks like a logfile somehow...

If i put this into text-only i get:

For me, it really looks like the system is pissed by some errors and try again and again. What do you think?

From the various files i read that the following parts gets updates
backup.bat

- boot.bin, bootload.bin (same content) = This is the bootloader, found in the first sector of the mainboard flash
- fgs.dnl = The flash content for the graphics board
- radio.dnl = This part is for the internal flash of the radio processor (V850)
- replace.btl = Some rule/tool to replace the existing bootloader of the unit with the boot.bin
- sdsapp.uli = Part for the speech recognition system (SDS) of the radio
- system.elf = Maybe a part of the base RTOS (because of the ELF format)

Re: Analyze flash dump of NX

Post by Go4IT »

I'm always thinking of where the Nucleus RTOS is storing it's files? There must be some kind of filesystem inside the Flash and i bet, the Nucleus Core is using it, beneath the RAM to store also logfiles and other things. If you look on the end portion of the flash you find many entries with readable text which looks similar to logmessages.
On an non-working system if found this at 0x27028A0 "No bootable partitions!.Invalid partition table.Error loading ROM-DOS.Missing ROM-DOS" and things like "Critical download error: file DL_DOWNLOADSERVICE, line 2874, data 34, errnum 35, filenum 5" or "new <NAVI > sw: version from 7.8.2008, 17:00, CRC 37b988ea" and many of them. This can't be random.
