Can not connect the TMS320DM6467 EVM to a Console Window

Other Parts Discussed in Thread: TMS320DM6467

Hi,

I have problem when trying to connect my DAVINCI TMS320DM6467 EVM to a console window (Tera-Term).

I followed instructions in TMS320DM6467 DVEVM Getting Started Guide (spruf88d.pdf) and tried to connect to EVM using UART (Console Window).
But after I set up the hardware (section 2.1 in the User Guide) and powered on the EVM, Console Window displayed nothing.

I make sure that the RS-232 cable works correctly and serial setting is followed the instruction in User Guide.

Does anybody got this problem before?  Please help me.
Thanks.

    1> Are you using DM6467 EVM or DM6467T EVM? Check what is printed on the EVM "TMS320DM6467 EVM"  (for DM6467 EVM) or "TMS320DM6467 EVM HD 1080P EVM" (for DM6467T EVM).

    2> Make sure S1 switch (next to JTAG connector) is set correctly: S1[1:0] = 11 (EMU0=1 and EMU1=1), means both switches should be set High, towards white reset button (SW1).

    3> Make sure Serial terminal settings are as per attached.

    4> Set to SPI boot (SW3 [8..1] = 00001110) for DM6467 EVM or  to NAND boot (SW3 [8..1] = 00000111) for DM6467T EVM.
    Switch settings are also shown in the pictures at the following link: http://processors.wiki.ti.com/index.php/GSG:_DM6467_DVEVM_Hardware_Setup

    SPI boot (DM6467 EVM) or NAND boot (DM6467T EVM) is not working means, the SPI ROM or NAND Flash is not programmed with proper U-Boot/UImage. You have to reprogram the board which needs CCS v3.3 and JTAG connection (needs XDS510 or XDS560).

    5> Set the board to UART boot ((SW3 [8..1] = 00001000)). You should see "BOOTME" message on UART console (like Hyperterminal, Teraterm, ...etc). This tells alteast the board is live. If you don't see "BOOTME" message, that means some thing is wrong with the boad. Contact Spectrum Digital in this case.

    Hi srirami,

    Thank you for your reply.

    I make sure that the evaluation board is "TMS32DM6467 EVM" and I followed the instructions in User Guide (similar with your answer).

    At step 5, nothing was displayed on HyperTerminal.

    I think I should contact with Spectrum Digital like you said.

    Regards.
