In Raspbian Jessie, udev rules exist that provide aliases for GPIO14:15 ( /dev/serial0) and the Bluetooth serial port ( /dev/serial1). The Gentoo stage 3 comes with the default Gentoo serial port configuration. Now that we have the base operating system in, we will need to do some file configuration by hand to get the peripherals working. Shows that the kernel modules were installed to the correct location. Partition type (type L to list all types): cĬhanged type of partition 'Linux' to 'W95 FAT32 (LBA)'. The bootable flag on partition 1 is enabled now.

There are no prebuilt kernel images for the Pi 3 in its arm64 mode. The content of the microSD card will be wiped during the install.

Gentoo install (or prefix install) on a PC.the raspberry pi cam will not work natively here.Īll the Pi 3 hardware is supported in 64-bit mode. A lot of work by a lot of people has almost brought a 64-bit Gentoo install on the Pi 3 down to almost a standard handbook install.Ĭurrently the raspberrypi-userland is not fully supported in 64-bit userland, therefore e.g. At the outset, it was difficult to install Gentoo on the Pi 3 in 64-bit mode. The Raspberry Pi 3 with a 64-bit capable CPU became available on Feb. 10.6 Alternative: Use the /boot/cmdline.txt file from a working Raspbian install.10.4 Alternative: Use the /boot/config.txt file from a working Raspbian install.8.2 Install the kernel to the microSD card.8.1 The Raspberry Pi Foundation provided files.7.2 Install a Gentoo repository snapshot.
