Hello vishnu prasad,
Please refer to the attached script, which we are using to generate Yocto release ISO.
Usage:
./giso.sh -d yocto_dir -p iso_prefix -c cache_compress_type
-d the full path of yocto folder
-p prefix of generated ISO name
-c cache packages compress type, value can be xz, bzip2 or gzip.
default compress type is xz.
Eg: $ ./giso.sh -p QorIQ-DPAA-SDK -d <path-of-yocto>
Thanks,
Yiping
