Abstract

Currently, we only support the compatible use of Arducam imx219 camera on TI SK-AM62A-LP development board. The following steps are only applicable to imx219 camera.

Meanwhile, Texas Instruments has made major changes to the AM62A SDK 9.2 version. SDK Versions before SKD 9.2 and after SDK 9.2 require different operating instructions. Please refer to the following contents:

Please follow the following steps to use the Arducam V3-Link camera kit with the TI SK-AM62A-LP starter kit board.

Software Guide before AM62A SDK 9.2

Flashing the Image onto Memory Card

  • Download the latest EDGE AI SDK.WIC.XZ image from the link above.

https://dr-download.ti.com/software-development/software-development-kit-sdk/MD-D37Ls3JjkT/08.06.00.45/tisdk-edgeai-image-am62axx-evm.wic.xz

a. Select the image you want to flash

b. Insert your microSD-Card into the Card Reader that is connected to your computer.

c. Click the Flash! button and wait for the programming to complete.

  • Completion

Wait for flashing to complete,Insert the programmed microSD card into SK-AM62A-LP, first power the V3Link d-ch adapter board, and then power the SK-AM62A-LP. This is very important and the order cannot be changed! ! ! After waiting for a while you can see the following screen on the display.

Add relevant drivers and change configuration

Log in to the system through the serial port

a. You can download PUTTY according to the link provided. https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html

b. Right-click the start button on the taskbar, select Device Manager, and you can see several new serial ports in Ports (COM&LPT).

c. Open PUTTY, select Serial, enter the newly added COM port, change the baud rate to 115200, click to open, there is no exact text description, the serial port terminal is fixed at the smallest port, I recommend opening all four ports and powering on again to view the output information.

d. The output information is as shown in the figure below. COM7 is a serial port terminal. Enter the user name root and there is no need to enter a password to log in to the system.

e. Download AM62ASK-V3Link.zip
