Huawei firmware. Unable to demangle symbol: _GLOBAL__D___gthread_once
Ya-Mir opened this issue · comments
Hello!
I'm have trubl with huawei firmware.
My setup:
Ghidra 10.2.3
Java Version 17.0.7
VxHunter latest
CPU: HiSil1210A Architecture: 64-bit ARMv8-A , Cortex-A53 (CPU: HISILICON - CortexA9 (ARM from bootlog)
VxWorks 6.7(8) (from boot log)
Message from Ghidra:

Thanks for very cool tools!
Hi @Ya-Mir , thank you for using VxHunter.
The Unable to demangle symbol and Failed to create ascii string errors should not affect the analysis procedure.
Does functions in firmware decompiled as expected?
hmm, looks like the symbol table is correct.
But disassembled codes at functions looks weird.
This firmware might compiled with optimization option enabled, you can setup the cpu type to ARM:LE:32:v8T(ARM V8 little endian with thumb enabled) and run VxHunter again.
Thanks for very cool support. Do you have any ideas how to extract other files from the firmware?
