: images for following boards are not generated: SAMA5D3 XPLAINED, SAMA5D4 XPLAINED, SAMA5D2 PTC EK
- However, no source code for these boards is removed
Demo Image for all boards. Choose headless (no video) or graphics option, your root filesystem flavor, flash and you're ready to go:
Demo Archive 2020.10 page
- NAND and SPI + eMMC media types were flashed using SAM-BA 3.3
Yocto Project SDK based on Linux4SAM 2020.10 release (Yocto Project 3.1.4 Dunfell)
And all goodies of previous Linux4SAM revisions!
New naming scheme:
- New naming scheme for Linux4SAM releases. The name will now reflect the year and month of the release, for easy identification of the moment in time of the release.
- This release we present now corresponds to 2020 April release, thus 2020.04.
New demo available for all previous SAMA5 boards and SAM9X60-EK board. Based on updated components:
- Linux kernel 5.4.x (+ LTS maintenance updates up to v5.4.41)
- AT91Bootstrap 3.9.2 with security fixes (Buildroot, OpenWrt); 3.9.3 with additional move to Python3 (Yocto Project only)
- U-Boot 2020.01 with PDA screen detection at boot time, FIT image support and overlay support. Check our FAQ for any questions. Additional support for unlocking and writing SST QSPI flashes in U-boot (saving environment to QSPI flash for example)
- Yocto Project 3.1 (Dunfell). First to benefit from the Long Term Support (LTS) plan.
- Buildroot generated from 2020.02.2 LTS revision using buildroot external
- OpenWrt Linux operating system : 19.07.2 stable branch
- Device tree overlays and FIT Image support
- New full featured graphical demos using the Microchip Ensemble Graphics Toolkit (EGT) 1.0 as a graphic library
- Integrated WILC driver and firmware version 15.4 . For any questions check FAQ and Applications pages
- Amazon Web Services GreenGrass (AWS GG) v1.10.1 is now included and ready to connect to AWS Cloud for all our sama5d2 based boards !
New kernel features:
- Integration of stable kernel updates up to v5.4.41
- Update WILC driver & firmware to 15.4.
- Integration of SAMA5D2-ICP board in the release
- Implement I2C bus recovery mechanism
- Allow using more than 4 GPIOs as CS in atmel-spi driver
- Add support for phylink in MACB driver
- Master clock register offset fixes for SAM9X60 in shutdown, reset controller and PM SoC drivers
- Improve power saving modes by disabling CPU PLL for SAM9X60
- Add SAMA5D2-ADC additional software trigger support (for example, sysfs trigger)
- Add real time timer (RTT) driver for SAM9X60
- Fix fast drop of VDDCORE on shutdown operations for SAM9X60
- Refactor reset controller driver
- Switch the AES and TDES crypto drivers to the skcipher API. Clean the drivers and add various fixes.
- Mainline SAM9x60 HWRNG support
- Add support for SHA204A (I2C) random number generator
- DMA drivers locking improvement and deadlock fixes
- Fix possible MMIO window size overrun in QSPI driver
- USB device controller (gadget) driver cleanup & fix for Vbus disconnect DMA issue.
- Add support for Micron/Aptina MT9V022 monochrome camera sensor for both ISC-based MPUs and ISI-based MPUs.
New Yocto Project/Buildroot/OpenWrt features:
- Full support for EGT (version 1.0 included)
- Moved to the new Yocto branch, Dunfell (3.1) LTS release
- Moved to new Buildroot release, 2020.02 LTS revision 2020.02.2
- Moved to new OpenWrt release, 19.07.2
- Firmware version 15.4 for WILC3000 and WILC1000 Wi-Fi and Bluetooth together with all the required software components (wpa-supplicant, hostapd and more). For any questions check FAQ and Applications pages.
- WILC demo apps are now available : Wilcbtapps and Websocket for the SAMA5D27 WLSOM1 EK board. Also included WiFi provisioning webpage.
- Yocto Project has deprecated Python2. We made a special version of AT91Bootstrap (v3.9.3) that uses Python3 instead of Python. There are no other differences between v3.9.2 and v3.9.3. Python is used by AT91Bootstrap only as a build dependency.
- Amazon Web Services GreenGrass (AWS GG) v1.10.1 is now included and ready to connect to AWS Cloud for all our sama5d2 based boards , on both Buildroot and Yocto Project distributions. The availability of ECC608 either as soldered on-board or as an addition through an expansion connector makes the solution secure, easy to use and seamless.
