Gnu hex dump windows

When option -d is in effect objdump will assume that any symbols present in a code section occur on the boundary between instructions and it will refuse to disassemble across such a boundary.

When option -D is in effect however this assumption is supressed. This means that it is possible for the output of -d and -D to differ if, for example, data is stored in code sections. If the target is an ARM architecture this switch also has the effect of forcing the disassembler to decode pieces of data found in code sections as if they were instructions.

In combination with --no-show-raw-insn this may be useful for comparing compiler output. When disassembling, print the complete address on each line.

This is the older disassembly format. Specify the endianness of the object files. This only affects disassembly. This can be useful when disassembling a file format which does not describe endianness information, such as S-records. When disassembling sections, whenever a symbol is displayed, also display the file offset of the region of data that is about to be dumped.

If zeroes are being skipped, then when disassembly resumes, tell the user how many zeroes were skipped and the file offset of the location from where the disassembly resumes. When dumping sections, display the file offset of the location from where the dump starts.

File segments may be relocated to nonstandard addresses, for example by using the -Ttext , -Tdata , or -Tbss options to ld. However, some object file formats, such as a. Instead, it shows the usual addresses, which are implicit for the target. In such cases the NOREAD attribute takes precedence, but objdump will report both since the exact setting of the flag bits might be important. Display a list showing all architectures and object formats available for specification with -b or -m.

Display the contents of non-debug sections found in separate debuginfo files that are linked to the main file. This option automatically implies the -WK option, and only sections requested by other command line options will be displayed.

Label the display using debugging information with the filename and source line numbers corresponding to the object code or relocs shown. Only useful with -d , -D , or -r. Specify the architecture to use when disassembling object files. This can be useful when disassembling object files which do not describe architecture information, such as S-records. You can list the available architectures with the -i option. If the target is an ARM architecture then this switch has an additional effect.

It restricts the disassembly to only those instructions supported by the architecture specified by machine. If it is necessary to use this switch because the input file does not contain any architecture information, but it is also desired to disassemble all the instructions use -marm.

Pass target specific information to the disassembler. Only supported on some targets. If it is necessary to specify more than one disassembler option then multiple -M options can be used or can be placed together into a comma separated list. Additionally, one can choose to have all the immediates printed in hexadecimal using hex. By default, the short immediates are printed using the decimal representation, while the long immediate values are printed as hexadecimal.

This option might be specified multiple times - only the latest value will be used. If the target is an ARM architecture then this switch can be used to select which register name set is used during disassembler.

Either with the normal register names or the special register names. This can be useful when attempting to disassemble thumb code produced by other compilers.

For AArch64 targets this switch can be used to set whether instructions are disassembled as the most general instruction using the -M no-aliases option or whether instruction notes should be generated as comments in the disasssembly using -M notes. For the x86, some of the options duplicate functions of the -m switch, but allow finer grained control. Note: intel-mnemonic implies intel and att-mnemonic implies att.

Specify the default address size and operand size. These five options will be overridden if x , i or i appear later in the option string.

For PowerPC, the -M argument raw selects disasssembly of hardware insns rather than aliases. For example, you will see rlwinm rather than clrlwi , and addi rather than li. All of the -m arguments for gas that select a CPU are supported. These are: , , , , , , , , , , , , , cl , , , , a2 , booke , booke32 , cell , com , ez4 , e , e , emc , emc64 , ex2 , e , e , efs , power4 , power5 , power6 , power7 , power8 , power9 , power10 , ppc , ppc32 , ppc64 , ppc64bridge , ppcps , pwr , pwr2 , pwr4 , pwr5 , pwr5x , pwr6 , pwr7 , pwr8 , pwr9 , pwr10 , pwrx , titan , and vle.

In addition, altivec , any , htm , vsx , and spe add capabilities to a previous or later CPU selection. If you disassemble without giving a CPU selection, a default will be chosen from information gleaned by BFD from the object files headers, but the result again may not be as you expect.

We can get the Byte value array of that. So it can get concatenated, or in this case, be the starting value of the byte array that will be at the content of the binary file. Once we have everything fetched and concatenated at the byte array we can perform a pipe operation to get a glimpse of what we're getting.

Then, we can convert it again, with hex-dump in order to see if we get the same byte values we saw back then at powershell output:. And we can use this file to concat it at the offset desire, let's say that we intend to write it from location 0x1A , we do something like:. And that's about that. Thanks a lot again for everything.

Feedback and suggestions are very welcome. NB: File2 is a reference file with no similar characters to File1. If unsure, then a workaround would be to fill File2 with 0x20, then for 2nd comparison fill File2 with 0x00 and replace the missing characters with 0x20 in the 1st comparison Hint: Check offset address.

Writing data bytes to a file is simple enough. Get some data, transform it to a byte array, then write that array to a file:. That won't help you any, though, if the bytes you're writing to the file aren't laid out correctly for whatever it is you're trying to do.

Edit: Given the sample input and output data from your updated question you need to write integer values in hexadecimal and decimal notation as byte sequences with varying byte order and also align the data.

The man page tells me:. Having no personal experience with SRecord, I take this to mean that you can use your input file as-is , using its raw bytes - no need for hex dumps and reformatting ; you merely need to follow its filename on the command line with option -binary. This assumes that your input file uses the desired character encoding; if not, convert it first, such as with iconv , or even a Get-Content -Encoding The acceptable input formats are described here ; format Ascii-Hex is similar to what Format-Hex produces, but would require non-trivial tweaking.

Generally, note that representations such as the ones created by Format-Hex are themselves invariably text , not "binary". They describe a sequence of byte values textually , which allows them to represent arbitrary data, including binary non-textual data.

With srec tools, we're able to put that data into the directions needed. Second Edit The sources of raw bytes that will be used are two. Third edit solution and summary : Thanks a lot to everyone!

And making use of the function: [BitConverter]::getBytes We can get the Byte value array of that. Next up is concatenation of the key string byte array of the JSON.
