|Name |Argument name |Description
|
|
|`-a` |`ARCH` |Build for architecture `ARCH`.
|
|
|`-B` |`BR2_CONFIG` |Add a single Buildroot option to the current build.
|
|
Example: `-B 'BR2_TARGET_ROOTFS_EXT2_SIZE="512M"'`
|
|
|`-b` |`BR2_FILE` |Also use the given Buildroot configuration fragment file.
|
|
Pass multiple times to use multiple fragment files.
|
|
|`-C` | |Skip the Buildroot configuration. Saves a few seconds,
|
|
but requires you to know what you are doing :-)
|
|
|`-c` |`CONFIG_SOMETHING` |Also use the given Linux kernel configuration, example:
|
|
`./build -c 'CONFIG_FORTIFY_SOURCE=y'`
|
|
Can be used multiple times for multiple configs.
|
|
|`-g` | |Enable gem5 build or force its rebuild.
|
|
|`-h` | |Show this help message.
|
|
|`-I` | |Enable initramfs for the current build.
|
|
|`-i` | |Enable initrd for the current build.
|
|
|`-K` |`KERNEL_CONFIG_FILE` |Use `KERNEL_CONFIG_FILE` as the exact Linux kernel
|
|
configuration. Ignore the default kernel config fragments.
|
|
|`-p` | |Pass extra arguments to the `rootfs_post_build_script`.
|
|
|`-S` | |Don't build QEMU with SDL support.
|
|
Graphics such as X11 won't work, only the terminal.
|
|
|`-v` | |Do a verbose build.
