General information on boot logs ================================ To gather good boot logs, you must set the debug level to Spew. If your board uses CMOS configuration[1], you can do it like this: nvramtool -w debug_level=Spew Else you will need to have to set the default log level at compile time, to do that go in "Console --->" in make menuconfig, then set "Default console log level" to SPEW Rereference: ------------ [1] in make menuconfig you should have: [*] Use CMOS for configuration values This option is also known as CONFIG_USE_OPTION_TABLE in Kconfig. Information trough SSH ====================== board_status.sh can gather information trough ssh with the -r option. When using "-r ", The script will attempt to log into root@. In order for "-r " to work, the script has to be able to log into the remote host's root account, without having to provide a password. That can be achieved with the use of SSH keys and ssh-agent. board_status.sh expects the remote host to have the following programs in its path: cbmem, dmesg Boot log gathering trough a serial port ======================================= When using -s , board_status.sh starts by retrieving the boot log trough the serial port. To produce such logs, power off the board, run board_status.sh with the right arguments, power on the board. At that point the logs will be displayed by board_status.sh as they are produced by the board. Enter will have to be pressed once the board has booted and is in a state where the script is able to log into that board. Publishing ========== The -u switch will publish the results: It will make a git patch out of the status information, that will be directly pushed in the board-status repository. It expects the user to already have an account in coreboot's gerrit instance.
