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.
Software Versioning
The BSP-Yocto-Ampliphy-AM62Ax-PD24.1.2 software release is largely based off of Texas Instruments’s v10.01.10 Processor SDK Linux release and shares much of the same components and features.

Linux Device Tree Summary
This is a summary of how the device tree source files (.dts) and the various include files (.dtsi) are broken down in the kernel. These files describe the hardware in a hierarchical and modular way to the kernel, connecting device drivers to the interfaces brought out by the carrier board.
Hardware Target |
Device Tree File Descriptions |
Filename |
|---|---|---|
KPB-07524-ALPHA.A1 (Default Kit) |
Default Device Tree (includes the other .dtsi files below) |
k3-am62a7-phyboard-lyra-rdk.dts |
Processor .dtsi - This file adds general support for the AM625x Processor from Texas Instruments |
k3-am62a7.dtsi |
|
SOM .dtsi- This file adds support for your specific SOM’s population options |
k3-am62a-phycore-som.dtsi |
|

k3-am62-phyboard-lyra-vm016-mipi.dts |
|
SPI0 Overlay |

|
GPIO Fan Overlay |
k3-am62x-phyboard-lyra-gpio-fan.dts |
|
Disable OSPI NOR Overlay |
k3-am6xx-phycore-disable-spi-nor.dts |
|
Disable RTC Overlay |
k3-am6xx-phycore-disable-rtc.dts |
|
Disable SOM Ethernet PHY Overlay |
k3-am6xx-phycore-disable-eth-phy.dts |
|
Switch from OSPI to QSPI SPI NOR Flash |
k3-am6xx-phycore-qspi-nor.dts |
If designing your own custom carrier board around the phyCORE-AM62Ax SOM, you will eventually define a custom device tree for your board that includes the .dtsi file for the SOM, which PHYTEC has provided for you. All the BSP changes custom for your application should eventually be consolidated into its own Meta Layer.

Interface Overview
The following table contains all interfaces connected to the phyCORE-AM62Ax’s connectors and each status.
Note
For simplicity reasons interfaces located in the MCU and WAKEUP domains have a prefix. Interfaces located in the MAIN domain might have a main_ prefix but it was not added here.
