This script is attempting to read binary data from an rpm file. If any of the bytes it is attempt to read is the binary value 0xa (i.e. a newline) then the script does not properly deal with this special case. Due to the behavior of command substitution, instead of fetching the value 0xa, the script makes an error and get the value 0 instead. The fix and the following explantion was taken from this post... https://unix.stackexchange.com/questions/10801/ how-to-use-bash-script-to-read-binary-file-content Command substitution $(…) strips final newlines in the command output. There's a fairly easy workaround. Make sure the output ends in a character other than a newline, then strip that one character.

QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
