MACE is a deep learning inference framework optimized for mobile heterogeneous computing platforms. – XiaoMi/mace. I’d like to copy an executable ELF file via: $ objcopy -O binary Unfortunately: $ chmod +x $./ results in: cannot execute. Answer in this case after hint from @Igor Skochinsky is: , ” x” j translatefuel. , “ax” j has.

Note – unique symbols are not converted.
The value of width plus the byte value set by the –byte option must not exceed the interleave breadth set by the –interleave option. Wildcard characters are accepted in sectionpattern. This defaults to This is obncopy default unless binutils was configured with –enable-deterministic-archives. If you do not specify outfileobjcopy creates a temporary file and destructively renames the result with the name of infile.
When objcopy generates a raw binary file, it will essentially produce a memory dump of the contents of the input object file. John Banks 73 7. All symbols and relocation information will be discarded. This length covers both address, data and crc fields. Select the width of the range with the –interleave-width option.
Apply –strip-unneeded-symbol option to each symbol listed in the file filename. Apply –localize-symbol option to each symbol listed in the file filename. When stripping symbols, keep symbol symbolname even if it would normally be stripped. IgorSkochinsky That was the clue I needed, thanks!
This option is the inverse of –add-section. In ELF files, this preserves all note sections in the output. Somehow I am not gni the section properly in the linker script file.

This option will be ignored if the input file has a known bfdarch. The exact set of these locations varies depending upon the distribution being used, but it typically includes:. However, see the –reverse-bytes option.
In this case, pass the original section name to –update-sectionand the original and new section names to –rename-section. This is the default. One a tnu binary which will occupy less space in RAM and in a distribution and the second a debugging information file which is only needed if debugging abilities are required.
A section length must be evenly divisible by the value given in order for the swap to be able to take place. Recall that ELF is quite a complex and versatile format, it specifies the starting address, the interpreter ld-linux 8 dynamic linkerthe several segments of the program etc. When stripping a file, perhaps with –strip-debug or –strip-unneededretain any symbols specifying source file names, which would otherwise get stripped.
In this case the output architecture can be set to bfdarch. In some cases -R will be useful to remove sections which contain information objcoyp is not needed by the binary file. Add a new symbol named name while copying the file.
Note that using this option inappropriately may make the output file unusable. Use bfdname as the object format for both the input and the obkcopy file; i. It does not have to be a file created by the –only-keep-debug switch. The LMA address is the address where the section will be loaded into memory at program load time. Make all other symbols local to the file, so that they are not visible externally.
Meaningful only for srec output. The kernel cannot guess them.

Convert debugging information, if possible. Matches zero or one character in a symbol name. Do not copy symbol symbolname from the source file.
Fill gaps between sections with val. Sets the section alignment.
Add a new section objcop sectionname while copying the file. Apply –weaken-symbol option to each symbol listed in the file filename. Reverse the bytes in a section with output contents.
Note – it is possible to use –rename-section and –update-section to both update and rename a section from one command line. The objcopy utility supports the following options:
