We are pleased to announce the release of Linux4SAM 6.0.
You'll find the packages for all boards at the usual place:
The source code is deployed on our github account:

Here are the main features:

New demo available for all SAMA5 boards and AT91SAM9x5-EK board. Based on updated components:
  • Linux kernel 4.14.x (+ LTS maintenance updates up to v4.14.73)
  • AT91Bootstrap 3.8.11 with new support for DMA load from SD-Card/eMMC and 8-bit bus eMMC detect & support
  • U-Boot 2018.07 with PDA screen detection at boot time, FIT image support and overlay support
  • Yocto Project 2.5.1 (Sumo)
  • Buildroot generated from 2018.02 revision using buildroot external
  • OpenWrt Linux operating system based on master branch of the reunified LEDE / OpenWrt project: 18.06
  • Device tree overlays and FIT Image support
New kernel features:
  • use of Device Tree overlays for board variants and auto-identification of PDA screens when hardware permits
  • handling for all low power modes ULP0/ULP1/Backup Self Refresh on SoC that support them
  • add support for PDA 5" screen TM5000/AC320005-5
  • add driver for the new Atmel I2S controller
  • ADC: add resistive touchscreen support to SAMA5D2
  • introduce ATECC508A driver (private key generation and ECDH key agreement)
  • QSPI: add Global Block Unlock support and SFDP tables to support SST26 QSPI flash memories
  • USB host: add the HSIC port support
  • USART: add ISO7816 support to serial driver
  • USART: add support for SPI mode in USART driver: spi-at91-usart
  • fix to sama5d2 shutdown controller
  • fix drive strength for NAND data pins on SAMA5D2-PTC-EK
  • fix Ethernet macb TX stuck under certain conditions (net: macb: restart tx after tx used bit read)
  • fix cts(cbc(aes)) and rfc4543(gcm(aes))) crypto modes
New Yocto Project/Buildroot features:
  • new whiteboard Qt application with improved performance
  • new wildwest Qt demo showing parallax effects with libplanes
  • new Qt application interactively demonstrating software vs hardware scene objects
  • new spacetouch application showing using all planes with a parallax effect
  • new defconfigs for node-red out-of-the-box working setup (only on buildroot)
  • new vision demo demonstrating machine vision with OpenCV (only on buildroot)
  • Qt Creator support
Libplanes with support for YUV plane formats (support video formats)

MPIO additions:
  • Add support for at91sam9x5
  • Add support to change board/cpu through environment variables
  • Add loopback test for SPI
iocontrol - add splash screen and startup time optimizations.

Demo Image for all boards. Choose with or without screen option, your root filesystem flavor, flash and you're ready to go:

NAND and SPI + eMMC media types were flashed using SAM-BA 3.2.3

I Just tried using this on SAMA5D3 Xplained and there is no communication on the USB serial when I use minicom or putty. Works fine with 5.8.
