Given a specification of bitfields defined e.g. as follows:
specfile:
{
"field1" : 8,
"field2" : 4,
"field3" : 4
}
and a set of values for setting defaults:
setterfile:
{
"field1" = 0xff,
"field2" = 0xf,
"field3" = 0xf
}
You can generate a binary packed blob as follows:
./blobtool specfile setterfile binaryoutput
binaryoutput: ff ff
The reverse is also possible, i.e. you can regenerate the setter:
./blobtool -d specfile binaryoutput setterorig
setterorig:
# AUTOGENERATED SETTER BY BLOBTOOL
{
"field1" = 0xff,
"field2" = 0xf,
"field3" = 0xf
}
This tool comes with spec/set files for X200 flash descriptor
and ICH9M GbE region, and can be extended or used to decompile
other data blobs with known specs.
