New in this Release
-------------------

In this release we switched away from the vendor bootloader.

**Yocto**
^^^^^^^^^

* **Yocto Update**: Update to Scarthgap (5.0.12)
* **Ethernet Names**: Ethernet interfaces have now predictable names with endX. Previous names with ethX are still supported as alternative names.
* **Introduce Ampliphy-Boot**: PHYTEC's new boot flow based on U-Boot Standard Boot.
* **Remoteproc Udev Rules**: Added udev rules for remoteproc cores.

**Linux Kernel**
^^^^^^^^^^^^^^^^

* **Kernel Update**: Update to v6.12.35 (tag: v6.12.35-11.01.05-phy6)
* **New Wifi/BL Overlay** Introduced the M2-CC3351 overlay for the new M.2 WiFi/BT module.

**U-Boot Bootloader**
^^^^^^^^^^^^^^^^^^^^^

* **Bootloader Update**: Update to U-Boot v2025.07 (tag: v2025.07-phy6) with various improvements and bug fixes.
* **Watchdog Update**: Start watchdog during the Linux boot process to capture boot failures.
* **RAUC Boot Update**: Use U-Boot's bootmeths RAUC

**Issues Fixed**
^^^^^^^^^^^^^^^^


**Known Issues**
^^^^^^^^^^^^^^^^

* **Flashcp Command Failures**: Occasional failures during verification in `flashcp`.
* **USB I/O Errors**: There may be I/O errors with **/dev/sdb** during the boot process from eMMC. However, no issues have been observed when reading from or writing to the drive after booting.
* **Boot Hang Issue**: The first-stage bootloader occasionally hangs in about 1% of all boot attempts on High Secure devices.
* **/dev/watchdog1**: A wrong interrupt source is configured in the Error Signaling Module (ESM) for ``/dev/watchdog1``, which should not be used. Systemd uses /dev/watchdog0 and is therefore unaffected by this issue.
