1. 介绍

This Quickstart guide describes the tools and provides the know-how to install and boot the Linux Board Support Package (BSP) for the phyCORE-AM62L FPSC Kit.

This kit is currently in Alpha Status. There are several topics to keep in mind while working with this kit and guide:

  • The phyCORE-AM62L FPSC will go through several functional changes during the Alpha Stage of development. Due to this, this Quickstart guide may change without any prior notice.

  • The phyCORE-AM62L FPSC has some functionality that is not currently operational. Please be aware of this when working with the Alpha Kit.

  • This Quickstart guide is only for booting and starting the basic functionality of the phyCORE-AM62L FPSC.

  • Hardware manual for the phyCORE-AM62L FPSC can be found here: Hardware Manual - phyCORE-AM62L FPSC/Libra Development Board (1627.0/1618.1) (L-1078e.A0)

  • Yocto Reference Manual for scarthgap can be found here: Yocto Reference Manual (scarthgap)

  • Pin Muxing Table - a complete list of all signal chains from processor to carrier board output. Signal level, signal type, and other useful information can be found here: phyCORE-AM62Lx FPSC Pin Muxing Table

The following manuals will be available in future releases of the phyCORE-AM62L FPSC:

  • BSP manual - a complete manual on the supported BSP. This includes documentation on how to build the BSP, install the built BSP, development tutorials and documentation on each board supported peripherals.

  • Pin Muxing Table - a complete list of all signal chains from processor to carrier board output. Signal level, signal type, and other useful information is also included.

For more information or details regarding the phyCORE-AM62L FPSC, please contact the PHYTEC Sales department.

警告

A full feature Libra FPSC board is shown here. Please note that this is an Alpha Kit, there will be continuous revisions being made to the phyCORE-AM62L FPSC SoM and Libra FPSC board. Due to this, components and features may not be available. Contact PHYTEC if there any questions regarding components and features for this Alpha Kit. To see which components are currently functional, refer to the phyCORE-AM62L FPSC release notes.

2.3. Additional (optional) equipment (not included in Alpha Kit)

  • Display (KLCD-AC209-xxxx)

2.4. Linux Host PC

Before you can work with the phyCORE-AM62L FPSC Board Support Package (BSP), you will need a host PC with the following minimum requirements:

  • A modern Linux operating host system either natively or via a virtual machine.

  • Ubuntu 22.04 LTS 64-bit recommended. Other distributions will likely work but note that some setup information as well as OS-specific commands and paths may differ.

  • VMWare Workstation, VMWare Player, and VirtualBox are possible solutions if you want to use a virtual machine.

  • Root access to your Linux host PC. Some commands in this guide will not work if you do not have sudo access (e.g. package installation, formatting an SD card).

  • At least 40 GB to 50 GB of free space on the build partition of the host PC.

  • An SD card reader, operational under Linux.

  • An active internet connection.

3. Connecting the Board

There a few manual connections that you will need to make before using the Libra FPSC.

3.1. Connecting the DEBUG USB interface

For the following steps, a console connection via USB is required. You can use the included USB Type-A to USB Type-C cable.

备注

For convenience, we have added a board UART to USB converter. This means, no RS232 interface is required during development for console communication between our carrier board and your host PC.

  • Connect your PC's USB port with the USB-C connector of the Libra FPSC (X14). After plugging the USB-C cable into X14 a red LED (D12) will light up to indicate a present USB bus voltage.

  • Your device manager will show four new COM ports. Select the first COM port. On the processor side, UART0 is the default debug UART of the A53 Cores (UART3 of FPSC). The second COM port can be used for general purpose usage. It equals to WKUP_UART0 on the processor side (UART2 of FPSC).

    警告

    Do not open the third or fourth COM port in a terminal program! With the third COM port a reset of the board can be triggered. With the fourth COM port the bootmodes can be set. Opening these COM ports can lead to boards not booting. This feature is not fully functional yet.

  • Setup your Terminal with the following parameters:

    • Speed: 115200 baud

    • Data bits: 8

    • Stop bits: 1

    • Parity: None

    • Flow control: None

3.2. Powering the Board

We recommend powering the Libra FPSC with the power supply (SV068) included in the kit. Connect the power supply to the Power-In connector (X8).

警告

If you are using a power adapter other than the one provided, please note the polarity of the power component X8. Ensure that your power adapter is correctly set up to use the polarity as shown below.

../../../_images/power-connector1.png

警告

If USB-PD port (X2) is mounted, do not use it in parallel with the 24V Power-In connector (X8). This may damage your device!

小技巧

Be aware that as soon as the Libra FPSC is supplied with power, the SD Card boot sequence will begin. Ensure that all cables are connected to the board!

4. Prebuilt Images

PHYTEC provides prebuild images and release notes for the phyCORE-AM62L FPSC. They can be downloaded here: https://download.phytec.de/Software/Linux/BSP-Yocto-AM62Lx/BSP-Yocto-Ampliphy-AM62Lx-ALPHA2/images/ampliphy-vendor/am62lxx-libra-fpsc-1/

There will be two images available: phytec-qt6demo-image and phytec-headless-image.

5. System Booting

The phyCORE-AM62L FPSC Kit is shipped with a pre-flashed SD card. It contains the phytec-qt6demo-image and can be used directly as a boot source.

How to build the BSP yourself will be described in the upcoming BSP manual.

5.1. Boot with SD-Card

  • To boot from an SD card, the bootmode switch (S1) needs to be set to the following position:

../../../_images/SD_Card_Boot1.png

  • 插入SD卡

  • Connect the target and the host with USB-C on (X14) debug USB

  • 给开发板通电

5.2. Boot from eMMC

Due to a known issue in early versions of the AM62L ROM Code, booting from eMMC is only supported in filesystem mode using the User Data Area (UDA). To enable this mode, we need to modify one of the "rescue" eFuse boot modes to support eMMC booting in filesystem mode.

警告

Fuses are One-Time Programmable (OTP), writing incorrect values can permanently brick your board. Double-check all commands before proceeding.

  • Burn the required eFuse:

    • Enable the VPP_1V8 regulator in U-Boot to provide power to the eFuse circuitry:

      u-boot=> regulator dev VPP_1V8
u-boot=> regulator enable

    • Program the fuse with the correct value:

      u-boot=> fuse prog 0xFF 1 0x0385850

  • Configure and Flash eMMC:

    • Enable eMMC UDA boot mode in U-Boot:

      u-boot=> mmc partconf 0 1 7 1
u-boot=> mmc bootbus 0 2 0 0

    • Boot into Linux:

      u-boot=> boot

    • Flash the eMMC with the correct Yocto image:

      target:~$ partup install phytec-qt6demo-image-am62lxx-libra-fpsc-1.partup /dev/mmcblk0

  • Set the S1 DIP switch to the correct configuration for eMMC boot and then power up the board:
