# We need to use Debian buster (currently testing) instead of Debian stretch
# (currently stable) for:
#
# linux ≥ 4.14
2017-10-08 21:18:48 +01:00
# Which includes the sdhost driver for faster SD card access and making the
# WiFi chip available, and has the WiFi driver enabled.

#
# raspi3-firmware ≥ 1.20171201-1
2017-10-08 21:18:48 +01:00
# Which includes a recent enough firmware version to correctly pass the MAC
# address to the kernel. This is a regression with Linux ≥ 4.12, see
# https://github.com/raspberrypi/firmware/issues/846
# Also, this package contains a Raspberry Pi 3-specific firmware file
# required by the WiFi driver.
