I have opcode, but not the chip that it runs on. How can I determine what instruction set architecture it is? - opcode
I have a firmware file that runs on an IOT device and I need to figure out what the firmware file is doing. I assume the file is opcode but I don't know what the architecture of the CPU it is running on is. Is there a way I can determine what the instruction set is just based on the code?
Thank you!
Here is a snippet of start of the file:

No, sadly there isn't. The only way to do this would be if the file had some sort of metadata (as in the case of ELF and PE files).

Had came accross this code that activated a function for a metamask contract on a website (not the full script). Is there any way to decrypt/deobfuscate this type of code?
No. This is obfuscated, and there is no generic way to deobfuscate solidity.
Application crashes when using vtkSmartVolumeMapper::New()
Crash happens in runtime on vtkSmartVolumeMapper::New() step. And it goes deep to vtkFixedPointVolumeRayCastMapper constructor. Don't understand how to tackle such an issue, please help Exception thrown at 0x00007FF73A60735A in smop-ptqt.exe: 0xC0000005: Access violation reading location 0x0000000000000000. Qt 5.15.6, VTK 9.1.0, ITK 5.2.1
Finally fixed crash on vtkSmartVolumeMapper::New() by using VTK9's new module approach in cmakelists.
So previously, while project used some vtk7.1 version.
CmakeLists treated VTK like this
find_package(VTK CONFIG REQUIRED PATHS "<some_path>/3rd_party/VTK/build/install_dir/lib/cmake/vtk-9.1" )
then used and so on.
target_link_libraries( ...${VTK_LIBRARIES} )
Now I applied module way

can someone give any solution for that.
Try to set a channel for default property in multiplexing selector agent1.sources.source1_1.selector.default=fileChannel1_1
Data channel lock error was corrected. But still could't do the multiplexing. Code as follows.

im try to deobfuscated the script but still the string error. Please if anyone know or how to decode this script. Or a method to find out what encryption is used. I wanna know what contains. Thank you in advance.
It's Base64 encoded, from the looks of it. I tried decoding it and got garbage data back, so either the string is incomplete, is not base64, OR (more likely, in my opinion) the script does something to the output of that base64 (such as decrypting it, maybe it's encrypted data stored as base64?) to make it readable.
Allocating memory in Flash for user data (STM32F4 HAL)
I'm trying to use the internal flash of an STM32F405 to store a bunch of user settable bytes that remain after rebooting. I'm using: uint8_t userConfig[64] __attribute__((at(0x0800C000))); to allocate memory for the data I want to store. When the program starts, I check to see if the first byte is set to 0x42, if not, i set it using: HAL_FLASH_Unlock(); HAL_FLASH_Program(TYPEPROGRAM_BYTE, &userConfig[0], 0x42); HAL_FLASH_Lock(); After that I check the value in userConfig[0] and I see 0x42... Great! When I hit reset, however, and look at the location again, it's not 0x42 anymore... Any idea where I'm going wrong? I've also tried: #pragma location = 0x0800C00 volatile const uint8_t userConfig[64] but I get the same result..
Okay I found an answer on the ST forums thanks to clive1. This example works for an STM32F405xG.
First we need to modify the memory layout in the linker script file (.ld file)
Modify the existing FLASH and add a new line for DATA. Here I've allocated all of section 11.
MEMORY
{
FLASH (RX) : ORIGIN = 0x08000000, LENGTH = 1M-128K
DATA (RWX) : ORIGIN = 0x080E0000, LENGTH = 128k
...
...
}
Manual for editing linker files on the sourceware website
In the same file, we need to add:
.user_data :
{
. = ALIGN(4);
*(.user_data)
. = ALIGN(4);
} > DATA
This creates a section called .user_data that we can address in the program code.
Finally, in your .c file add:
__attribute__((__section__(".user_data"))) const uint8_t userConfig[64]
This specifies that we wish to store the userConfig variable in the .user_data section and const makes sure the address of userConfig is kept static.
Now, to write to this area of flash during runtime, you can use the stm32f4 stdlib or HAL flash driver.
Before you can write to the flash, it has to be erased (all bytes set to 0xFF) The instructions for the HAL library say nothing about doing this for some reason...
HAL_FLASH_Unlock();
__HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_EOP | FLASH_FLAG_OPERR | FLASH_FLAG_WRPERR | FLASH_FLAG_PGAERR | FLASH_FLAG_PGSERR );
FLASH_Erase_Sector(FLASH_SECTOR_11, VOLTAGE_RANGE_3);
HAL_FLASH_Program(TYPEPROGRAM_WORD, &userConfig[index], someData);
HAL_FLASH_Lock();
