AM62A7: [AM62A7] [E2] The serial port can be recognized,cannot connect to the board.

Part Number: AM62A7

Hi TI,

I am using the AM62A    E2 development board purchased by our company, and I use it in the same way as the E1 board. The serial port can be recognized, but I cannot connect to the board through the serial port. What could be the reason?

Best Regards!

  • Hi Daohong,

    Are you using Linux SDK prebuilt binaries to verify the boot on your setup? Have you created the SD card with pre-built binaries?

    This will help route your query to the right expert.

  • Hi Suren,

    My operating steps are as follows:

    1.Download the AM62A Linux WIC Image.

    2.Write the WIC Image to SD Card

    3.Replug the SD card reader back into the PC.

       rename tiboot3.bin to tiboot3-default.bin.

       rename tiboot3-am62ax-gp-evm.bin to tiboot3.bin.

    4.Insert the SD card to the EVM

    5.Open Windows Device Manager and it shows 4 COM ports associated with the EVM

    6.Use a serial terminal emulator such as MobaXterm to connect to the first port. Configure the serial port setting to 115200 baud rate, 8 bit, no parity, 1 stop bit, no flow control.

    But unable to connect.

    Is the UART driver version old? Is there a new UART serial driver?

  • Hi Daohong,

    Your board seems to be AM62A LP board which is HS-FS device. Once you have the WIC image flashed, you don't need to rename tiboot3.bin. 

    The default tiboot3.bin is for HS-FS and should boot out of the box.

    Can you just try to use the tiboot3-default.bin as tiboot3.bin and give it a try.
