We have wanted to do this since forever, but the last straw was gem5 aarch64, which runs too fast, and makes it very hard to write "root" withing 60 seconds! Another possibility to solve that would have been to find an answer for: https://unix.stackexchange.com/questions/340333/how-can-i-get-bin-login-to-not-timeout which we didn't, but not typing root at all is even better. Take this opportunity to document how to login into user0. sshd: automate and document further gdbserver: automatically startup internet on /gdbserver.sh

|Name |Argument name | Description
|
|
|`-a` |`ARCH` | Build for architecture `ARCH`.
|
|
|`-b` |`BR2_FILE` | Also use the given Buildroot configuration fragment file.
|
|
Pass multiple times to use multiple fragment files.
|
|
|`-B` |`BR2_CONFIG` | Add a single Buildroot option to the current build.
|
|
Example: `-B 'BR2_TARGET_ROOTFS_EXT2_SIZE="512M"'`
|
|
|`-c` |`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 :-)
|
|
|`-g` | | Enable gem5 build and disable QEMU build. You also need
|
|
to use `-G` or `-- gem5-reconfigure` to rebuild gem5
|
|
after the initial build.
|
|
|`-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_fragment`.
|
|
|`-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.
