**patchelfcrc** -l -g word --start-magic=0x12345678 --end-magic=0x8754321 -p crc-32-mpeg -f bare -O .outputsection -S .text executable.elf
: Calculate the CRC over *.text* section and place the result in the *.outputsection* section.
The output sections start and end are checked for the given magic numbers in order to assure correct memory layout.
*CRC-32-MPEG* is used as CRC algorothm.
*CRC-32-MPEG* is used as CRC algorithm.
The memory is interpreted as *little endian* and the CRC calculation granularity is a 32 bit *word*.
