CMOS.layout
This page explain the workings of the CMOS.layout file. The CMOS.layout file can be linked into a board specific environment. By creating the cmos.layout file in the board directory. and set the HAVE_OPTION_TABLE in the Kconfig file of the board.
The CMOS layout file must contain the following sections;
- entries
- enumerations
- checksums
entries section
enumerations section
checksums section
The checksums section has one variable with three parameters;
checksum <startbit> <endbit> <start-of-checksumbit>
The <startbit> parameter is the bit position where the calculation of the checksum starts from.
The <endbit> parameter is the bit position there the calculation of the checksum starts on.
The <start-of-checksumbit> parameter is the bit position there the checksum will be stored, there must be space for 16 bits of checksum data.
Example;
checksum 392 983 984
