From: Stephen Warren <[email protected]> The flashing process resets the U-Boot environment to the built-in default. Allow the user to specify some non-default values to be set before saving the environment. This can be useful e.g. to set up the default boot target:
./tegra-uboot-flasher flash --env boot_targets dhcp beaver Signed-off-by: Stephen Warren <[email protected]> --- v2: * Don't fail if no --env cmdline options are used. * Enhance help text to: - Explicitly mention that the option can be used multiple times. (in --help output only, not the short help) - Say "--env VAR VALUE" not "--env ENV ENV" so the syntax is clear. --- tegra-uboot-flasher | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/tegra-uboot-flasher b/tegra-uboot-flasher index c9eb811db937..ea36ba1efd7a 100755 --- a/tegra-uboot-flasher +++ b/tegra-uboot-flasher @@ -195,6 +195,9 @@ def func_flash(): # Perhaps U-Boot should set $boardname based on the ID EEPROM; then we wouldn't need this if config['dtbfn-extra'] != '': bootcmd += 'setenv board ' + boardname + config['dtbfn-extra'] + ' ; ' + if args.env: + for (var, value) in args.env: + bootcmd += 'setenv %s %s ; ' % (var, value) bootcmd += 'saveenv ; ' # To update the bootloader, reset. # If wanting to run installer, set installer_args.configname in environment, 'run bootcmd' @@ -283,6 +286,10 @@ parser_flash.add_argument('--flash-image', type=str, help='The flash image to write, instead of U-Boot itself') parser_flash.add_argument('--gen-only', action='store_true', help='Just create the work-dir; don\'t actually flash the image') +parser_flash.add_argument('--env', type=str, nargs=2, action='append', + metavar=("VAR", "VALUE"), + help='Set a U-Boot environment variable after flashing.
