eimgfs's Issues

Windows Embedded Automotive 7 - Filesystem?

Just want to say thank you for all of your work over the years; it's been ~15 years (Wizard era!) since I last delved into wince/wm, having recently returned due to a project, I see the community (what's left) is still heavily reliant upon your hard work!

I'm working on a car radio running Windows Embedded Automotive 7 - a very limited environment to start with.

I managed to get serial access and then get to one of the test modes in the bootloader for memory read/write/test and from there slowly dump over serial.

eimgfs finds the 2 bootloaders (XIPs with a single nk in each) and the traditional xip which extracted perfectly (thank you!) however there's some kind of filesystem I can't identify; looking at the dump the strings marry up with a series of PEs but no recognisable PE header.

Appreciate this is not an issue/bug, but any help or pointers would be greatly appreciated!

BL 0x00000000
BL2(?) 0x00060000
XIP 0x001c0000

Believed filesystem start is around 0x00AC0000

Seg fault on GPS firmware

Hi !
Thanks a lot for this tool.
I have a 1GB firmware image of a GPS that contains WinCE files and programs.
The firmware extracted may be partially corrupted (less than 20 bits over 1GB may be flipped).
My goal is to extract all files from the firmware image.
eimgfs is detecting an xip filesystem and then crashing on a seg fault (on Linux and on Windows as well).

$ eimgfs img.bin -r -v -o 0x200000

Segmentation fault (core dumped)

I believe the first 4 lines are only missing libraries on Linux and does not appear on Windows.
On both platform eimgfs crashes.
I found the offset by using binwalk on the file :

2097152       0x200000        Windows CE memory segment header, TOC address: 0x0
2116520       0x204BA8        Windows CE image header, image start: 0x30305800, image length: 172377648
8849408       0x870800        Windows CE memory segment header, TOC address: 0x4005BE34

Any idea ?

Thanks.

Instruction on how to build on Windows?

Hello. Could you please provide a little more details on how to build eimgfs on Windows with modern PSDK? I guess I will need mingw + openssl/boost, right? Because Makefile.win32 seems not to be in mssdk nmake format. Thanks in advance.

can't extract this in any way... any clues?

I dumped the flash of a windows ce6 system (car radio/multimedia)

https://mega.nz/file/MtJ0TbBQ#OZPtoF1hyFR68iYaCxO0ImnxTgVzJXYdQA2vU7rWM3E

I can't find a way to extract it except binwalk which returns:

52449280 0x3205000 Windows CE memory segment header, TOC address: 0x0

List of files shown, but -extractall doesn't work

EXCEPTION: b000ff before start of map

I have a WinCE bin file that's reporting the "EXCEPTION: b000ff before start of map" error.

map=88, off=00000800
EXCEPTION: b000ff before start of map

Where would I start on fixing this? I can provide the bin file.
