board: raspberrypi: don't generate a marked kernel

2017-01-26T21:35:15+00:00

We no longer use the marked kernel. Cc: Peter Seiderer Signed-off-by: Baruch Siach Reviewed-by: "Yann E. MORIN" Signed-off-by: Peter Korsgaard

board: raspberrypi: use regular kernel image

2017-01-26T21:35:05+00:00

Since release 4.4 a kernel without a trailer is assumed to be device tree capable. Since our Raspberry Pi defconfigs all use the newer firmware we can just use the regular kernel image. https://www.raspberrypi.org/documentation/configuration/device-tree.md Tested on Raspberry Pi 3.

raspberrypi3: fix serial console (load pi3-miniuart-bt overlay)

2016-09-18T17:21:18+00:00

- enable BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS in raspberrypi3_defconfig - add copy of rpi-firmware/overlays directory to boot partition in genimage-raspberrypi3.cfg - enhance post-image.sh script to add 'dtoverlay=pi3-miniuart-bt' on request - add BR2_ROOTFS_POST_SCRIPT_ARGS="--add-pi3-miniuart-bt-overlay" in raspberrypi3_defconfig Signed-off-by: Peter Seiderer Signed-off-by: Thomas Petazzoni

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.
