netc_switch standalone

netc_switch standalone#

Overview#

The NETC Switch standalone demo application demonstrates how to use NETC switch standalone for lowest power, with suspending all other cores.

Supported Boards#

IMX943-EVK
Hardware requirements

  • Micro USB cable

  • IMX943-EVK board

  • 12V~20V power supply

  • Personal Computer

Board settings

NETC switch performs L2 switching on SGMII5/J30 and SGMII6/J31 ports. Default mode is 1000M speed and full-duplex, which can be changed in app.h.

#define EXAMPLE_SWT_PORT_SPEED kNETC_MiiSpeed1000M #define EXAMPLE_SWT_PORT_DUPLEX kNETC_MiiFullDuplex

Prepare the Demo

  1. Connect 12V~20V power supply to the board.

  2. Connect a micro USB cable between the host PC and the J15(FTDI_DEBUG) USB port on the target board.

  3. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  4. Program the Linux BSP to SD/eMMC. Then program flash.bin of this demo.

  5. Switch SW1 to power on the board.

Note: the flash.bin is flash_all target with mx94evknetc.cfg System Manager image. For A core Linux BSP, it should be booted with imx943-evk-netc-rpmsg.dtb.

Running the demo

When the demo runs, the log would be seen on the terminal like below.

NETC Switch standalone demo.
Please suspend others cores for lowest power...
NETC switch will keep L2 switching working.

Suspend other cores for lowest power. For A core, execute echo mem > /sys/power/state. For M7 cores power mode switch demo, enter d and s. For M33 SM, execute idle.

Waking up other cores can be via PWR_ON/OFF button.

IMX943-ORANGEBOX
Hardware requirements

  • Mini/micro USB cable

  • IMX943-ORANGEBOX board

  • 12V~20V power supply

  • Personal Computer

Board settings

NETC switch performs L2 switching on switch port0 and port1. Default mode is 1000M speed and full-duplex, which can be changed in app.h.

#define EXAMPLE_SWT_PORT_SPEED kNETC_MiiSpeed1000M #define EXAMPLE_SWT_PORT_DUPLEX kNETC_MiiFullDuplex

Prepare the Demo

  1. Connect a USB cable between the host PC and the J12(DEBUG_USB) USB port on the target board.

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Program the Linux BSP to SD/eMMC. Then program flash.bin of this demo.

  4. Connect 12V~20V power supply to the board.

Note: the flash.bin is flash_all target with mx94evknetc.cfg System Manager image. For A core Linux BSP, it should be booted with imx943-orangebox-netc-rpmsg.dtb.
