* raspberrypi, raspberrypi2: add a serial consoleGravatar Luca Ceresoli2016-04-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* rpi-firmware: modify settings for Pi 2Gravatar Floris Bos2015-05-021-1/+1
| | | | | | | | | | | | | | | | Remove low-level settings from config.txt like arm_freq and sdram_freq. The defaults should be good for most and differ by Pi model. E.g. the Pi 2 runs at 900 Mhz by default, setting arm_freq=700 like we had previously would underclock it. Add short description in comments to options. Mention initramfs option. Remove obsolete options from cmdline.txt Signed-off-by: Floris Bos <bos@je-eigen-domein.nl> Reviewed-by: "Yann E.

* package/rpi-firmware: updateGravatar Yann E. MORIN2013-06-071-0/+1
Updating brings in a new bootloader that enables more free codecs: MJPEG, VP6, VP8, Ogg Theora and Ogg Vorbis Also, the command-line definition has moved to its own file, now. Although the legacy 'cmdline' variable seems to still be supported for a little while, better switch now than forget when we upgrade later. Update the RPi board readme accordingly.
