3 AM574x IDK EVM (TMDSIDK574)

Contents

3.1 Board Overview

The AM574x Industrial Development Kit (IDK) is a development platform for evaluating the industrial communication and control capabilities of Sitara AM574x/2x processors for applications in factory automation, drives, robotics, grid infrastructure, and more. AM574x/2x processors include dual PRU-ICSS (Programmable Real-time Unit for Industrial Communications) subsystems which can be used for industrial Ethernet protocols such as Profinet, EtherCAT, Ethernet/IP, and others. The TMDXIDK574 breaks out six ports of Ethernet, four of which can be used concurrently: 2x Gb Ethernet ports and 2 x 10/100 Ethernet ports from the PRU-ICSS subsystems.

Target board.

[2]

Target YAML-file located in the kas/targets directory.

[3]

Target machine name stored in the MACHINE BitBake variable for selected Target YAML.

[4]

Recipes that will be built by default for the target. In Section 3.2.2, you can find list of supported recipes for the target images, which you can build in addition to the default recipes using optional --target option in build command (see Section 3.3).

[5]

External or internal data storage where the TanoWrt operating system is running.

	tanowrt-image-full-swu	All	Standard TanoWrt image and firmware upgrade image. When building this image, tanowrt-image-full will also be built as dependency.
	tanowrt-image-full-swu-factory	am574x-idk-emmc.yml	Factory installation image for standard TanoWrt image. When building this image, tanowrt-image-full and tanowrt-image-full-swu will also be built as dependencies.

[7]

Image recipe name. This name can be used as argument for --target build command option (see Section 3.3 section).

3.3 Build

Please read the common information on how to perform a TanoWrt images build and preparing the build environment in section “Building TanoWrt”.

See also

• See section Section 3.2.1 to select the required target YAML file (<target-yml>).

• See section Section 3.2.2 to select the required root filesystem image recipe (<target-recipe>).

• See section Section 3.5 for detailed information about the produced build artifacts.

3.3.1 Examples

3.3.1.1 Build Default Images for AM574x IDK EVM Board

For microSD Card

$ kas build targets/kas/am574x-idk-sd.yml

Default images will be produced to boot and run from the microSD card on the AM574x IDK EVM target board.

For Internal eMMC Flash

$ kas build targets/kas/am574x-idk-emmc.yml

An initial factory installation image will be generated, intended to run from the SD card. The installer image will install the default image to the internal eMMC flash memory and further the AM574x IDK EVM board will boot and run from the eMMC flash memory.

3.4 Partitioning Layouts

3.4.1 microSD

The partitioning and data layout of the microSD card image for the AM574x IDK EVM board are shown in the figure below.

3.6 Writing Images

3.6.1 Writing Image to microSD Card

No special information about writing images to microSD card for AM574x IDK EVM board. See common instructions in Writing Images to SD Card or USB Flash Drive section.

Examples

Writing factory installation image for the am574x-idk-emmc.yml target to the microSD card /dev/mmcblk1:

$ dd if=tanowrt-image-full-swu-factory-am574x-idk-emmc.sdcard.img of=/dev/mmcblk1

Writing bootable card image for the am574x-idk-sd.yml target to the microSD card /dev/mmcblk1:

$ dd if=tanowrt-image-full-am574x-idk-sd.sdcard.img of=/dev/mmcblk1

3.6.2 Writing Image to eMMC Flash

For the initial flashing of the internal eMMC memory it is recommended to use the special image of the initial factory installation. If you choose a build target (see Build Targets for details) that assumes using the factory installation image for the initial flashing of the device, a factory installation image (<rootfs-image>-swu-factory-<MACHINE>.sdcard.img) will be automatically generated during the build process (see Build). To write the factory installation image to a SD card, follow the instructions from Writing Images to SD Card or USB Flash Drive section.

When you boot device from the prepaired SD card with factory installation image the installation of TanoWrt to the internal eMMC flash memory will be done automatically. The detailed installation log is available on the debug UART. After the installation is complete, the board will reboots automatically. When the device is rebooted, the installed system will be booted from the internal eMMC flash memory.

Caution

Be aware that during the installation all existing data on the internal eMMC flash memory will be permanently lost.

3.7 Booting and Running

3.7.1 Choosing Boot Mode

The AM574x IDK EVM is configured by default to enable U-Boot/Linux boot from the microSD card. The secondary boot device selected is QSPI1.

3.7.2 Choosing Ethernet Mode

The AM574x IDK EVM supports up to four 100 Mbit Industrial Ethernet ports attached to the PRU-ICSS subsystems and up to two Gigabit (1000 Mbit) Ethernet ports connected to the integrated Ethernet switch. The final number of available ports depends on the configuration options. The default configuration provides two 100 Mbit Industrial Ethernet ports and two Gigabit (1000 Mbit) Ethernet ports.

3.7.3 Booting from microSD Card

1. Insert the microSD card into the slot on the AM574x IDK EVM board (power is off).

2. Power on board.

3. TanoWrt will be booting from microSD card.

4. Log in to system using default credentials.

3.8 Serial Console

The debug serial console on the AM574x IDK EVM board is accessible via the Micro USB connector on board. The FTDI bridge device provides both XDS100V2 JTAG emulation and UART Console over the USB. Its USB connector is J19 and it is also a USB Micro-AB connector but it only operates in device (slave) mode with the FTDI bridge device.

The default serial console settings for AM574x IDK EVM for U-Boot and kernel are described in the table below.

Parameter	Value
Baudrate	115200
Data bits	8
Stop bits	1
Parity	none
Flow control	none

3.9 Default Network Configuration

By default Ethernet 1 and 2 ports (eth0 and eth1 interfaces) are joined into a bridge (br-lan interface) with enabled RSTP protocol. Bridge (br-lan) configured with static IP address 192.168.0.1/24 with enabled DHCP server.

Ethernet ports 1 and 2 (eth0 and eth1) have LLDP enabled by default.

PRU-ICSS ethernet ports 3 and 4 (eth2 and eth3 interfaces) are not configured by default.

3.10 Web User Interface

The WebUI can be accessed via Ethernet ports through HTTP(s) protocol. You must see something like this in browser after you logged in:
