frugy - FRU Generator YAML

This is a tool which generates EEPROM images according to the IPMI FRU standard from YAML configuration files. It can also parse a FRU EEPROM image and write its contents to a YAML file, or dump them to stdout.

Installation

From PyPI:

pip3 install frugy

From GitHub:

pip3 install git+https://github.com/MicroTCA-Tech-Lab/frugy

Usage

$ frugy --help
usage: frugy [-h] [--version] [-o OUTPUT] [-w] [-r] [-d]
             [-e EEPROM_SIZE] [-s SET] [-t] [-b] [-c] [-l [LIST]]
             [-v VERBOSITY]
             [srcfile]

FRU Generator YAML

positional arguments:
  srcfile               Source file for reading

optional arguments:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  -o OUTPUT, --output OUTPUT
                        output file (derived from input file if not set)
  -w, --write           FRU write mode (convert YAML to FRU image), default
  -r, --read            FRU read mode (convert FRU image to YAML)
  -d, --dump            dump FRU information to stdout (same as -r -o -)
  -e EEPROM_SIZE, --eeprom-size EEPROM_SIZE
                        pad FRU image to match EEPROM size in bytes (only
                        valid in write mode)
  -s SET, --set SET     set FRU record field to a value (only valid in write
                        mode)
  -t, --timestamp       set BoardInfo.mfg_date_time timestamp to current UTC
                        time (only valid in write mode)
  -b, --broken          enable workaround to parse Opal Kelly EEPROMs
  -c, --ignore-checksum-errors
                        ignore checksum errors when parsing a FRU image
  -l [LIST], --list [LIST]
                        list supported FRU records or schema of specified
                        record
  -v VERBOSITY, --verbosity VERBOSITY
                        set verbosity (0=quiet, 1=info, 2=debug)

Examples

frugy damc-fmc2zup.yml

Read damc-fmc2zup.yml configuration, generate FRU image damc-fmc2zup.bin.

frugy damc-fmc2zup.yml -o fmc2zup_fru_eeprom.bin -e 2048

Read damc-fmc2zup.yml configuration, generate fmc2zup_fru_eeprom.bin, make it 2048 bytes (pad with 0xff).

frugy damc-fmc2zup.bin -r

Read and parse FRU image damc-fmc2zup.bin, generate YAML file damc-fmc2zup.yml.

frugy dmmc-stamp.yml -s BoardInfo.board_serial_number=Rev.A -s ProductInfo.product_version=0.01-alpha -t

Read dmmc-stamp.yml, generate FRU with board_serial_number set to REV_A, product_version to 0.01-alpha and mfg_date_time to current UTC time.

frugy -l

Show list of all supported FRU records.

frugy -l PointToPointConnectivity

Show layout of the FRU record called 'PointToPointConnectivity'.
