board/raspberrypi/post-build.sh: only tweak /etc/inittab if available

2016-08-26T13:37:17+00:00

As pointed out in bug #9161, we don't always have an inittab file (if systemd or no init is used), so the post build script should only try to tweak it if present. Signed-off-by: Peter Korsgaard Signed-off-by: Thomas Petazzoni

boards/raspberrypi0: new board

2016-05-08T13:54:30+00:00

Add support for the rpi-0, which is basically a rpi (model A+) in a smaller form-factor. This one does not have an ethernet port, so we just remove it from the configuration (or we could use the existing rasbperrypi_defconfig and suffer from a longer boot time because of the waiting for eth0).

configs: add Raspberry Pi 3 defconfig

2016-04-25T12:07:58+00:00

So far identical to the rpi2 one except for the dts file as the SW runs in 32bit mode. [Peter: extend commit message] Signed-off-by: Ubaldo Porcheddu Signed-off-by: Peter Korsgaard

raspberrypi, raspberrypi2: document the two consoles (UART+HDMI)

2016-04-18T22:12:23+00:00

The defconfigs for the Raspberry Pi boards start a console on HDMI in addition to the classic one on UART. Document this feature in the readme. Cc: Yann E. MORIN Cc: Arnout Vandecappelle Cc: Thomas Petazzoni Signed-off-by: Luca Ceresoli Acked-by: "Yann E. MORIN" Signed-off-by: Thomas Petazzoni

raspberrypi, raspberrypi2: add a serial console

2016-04-18T11:36:11+00:00

The current Buildroot defconfigs for Raspberry Pi and Raspberry Pi 2 instantiate a console on tty1, which appears on HDMI. Add a console on the serial port (ttyAMA0) to be more consistent with other defconfigs and provide a better out-of-the-box experience to users used to have a serial console from Buildroot defconfigs. This requires three changes: 1. have two 'console=' entries in the kernel command line: tty1, then ttyAMA0; 2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts a getty on the last console= passed to the kernel, ttyAMA0; 3. add a new getty on tty1 to the generated inittab. Step 2 is actually obtained by removing BR2_TARGET_GENERIC_GETTY_PORT entirely from the defconfigs, since "console" is the default value. Step 3 requires a post-build script since the Buildroot makefiles can configure only one console. Note: instead of simply adding a new getty on ttyAMA0 (which would work) this patch actually changes BR2_TARGET_GENERIC_GETTY_PORT to instantiate a console on UART, then adds back tty1 via post-build.sh. This is done only to avoid the "GENERIC_SERIAL" comment where we instantiate an HDMI console, then instantiate a really-serial console on another line. The result is these two inittab lines: console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL tty1::respawn:/sbin/getty -L tty1 0 vt100 # HDMI console Cc: Yann E.

configs/raspberrypi*: update them to use genimage

2015-12-31T14:22:48+00:00

Update the raspberrypi and raspberrypi2 configs to use genimage directly to build the image. Update the documentation to reflect this, and drop the volatile rootfs option since it doesn't make much sense and it's not easily integrated with the genimage configurations.

boards/raspberrypi: update instructions

2015-06-30T12:31:17+00:00

Now that we have a sanitised set of defconfig files, and we no longer support non-DT setups, update and simplify the board readme file. Signed-off-by: "Yann E. MORIN" Cc: Floris Bos Cc: Pascal de Bruijn Signed-off-by: Thomas Petazzoni

configs/raspberrypi: update the DT-enabled config

2015-06-30T12:30:23+00:00

Update to the latest stable kernel version; build an in-tree DTB; use a in-tree defconfig; enable C++ (to match what we have in the non-DT variant); do not install DTB overlays (this minimalist config does not make use of them). Generate the DTBs for both the "original" variant (A and B) and the "Plus" variant (A+ and B+). Drop our custom linux defconfig file now we use an in-tree one. Signed-off-by: "Yann E.
