DM6467 EVM Boot Up

Other Parts Discussed in Thread: TMS320DM6467T

We tried to bring up the DM6467 Evaluation board, but no success so far.

It seems no firmware or code burned in the eval. board, got "BOOTME" prompt from RS232 display only.

Also in the "DM6467 Getting Started Guide" page 9 for "Installing Software Components" section:

1. Complete the steps,( 1 through 8 ) mentioned in the "Installing Software Components" page to install DVSDK package.

But there is no "steps 1 through 8" can be found in this page.

This is the first time our engineers get on the Davinci processor, like to at least bring up the board by ourselves first.

Is there any help we can get from TI?

 

Can you please advise as to what may be the issue?

    Hello,

    When you see "BOOTME", what boot mode are you in? Please try setting BM[3:0] to 0111 or 1110 and see if it makes a difference.

    Spectrum digital has some CCS testcase, is that what you are looking for, or do you want to flash the NAND and bring up Linux?

    We want to boot to bring up Linux via NFS root mounted filesystem.  We want to know how to configure the board to boot the Uboot bootloader, interrupt the Uboot bootloader via the serial debug port, and configure the NFS boot parameters to boot our NFS root filesystem.

    I can't tell if the board already has the Uboot bootloader flashed already.  Do I need to flash the Uboot boatloader somewhere in flash, or is it already flashed?  What binary file holds the Uboot bootloader and how do I flash it in the correct spot?  Then, once it's flashed, how to I configure the board to boot the Uboot bootloader?  Are there switches or jumpers on the board that control which bootloader to boot?

    Hi,

    You can start with this site: http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_2_00/latest/index_FDS.html

    I'd suggest you first read spruf88e.pdf the DM6467 Getting started guide, it should give you a good idea on how to do what you plan to do.

    You might to reflash the NAND just in case the previous image is corrupted. The tools and images are in the DVSDK\PSP directory.

    Please do let me know if you the above resources don't address all your questions.

    All of the instructions in the spruf88e.pdf DM6467 Getting started guide assume that I can interrupt the U-boot bootloader from the serial debug port and gain access to the U-boot shell.  However, after setting the proper switches as instructed by the EVM Hardware Setup section,  all I see on the serial console is "BOOTME" and I can't seem to interrupt anything.

    I thought I must reflash the NAND just as you suggested.  I flashed the system from a Dos command prompt window using the windows utility sfh_DM646x.exe that was part of the board-utils-dm646x.tar.gz that I pulled down from:

    http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/dvsdk/DVSDK_3_10/latest/index_FDS.html

    I did a NAND flash using these two files:
        dm6467t_495_ubl.bin file that was in the board-utils-dm646x.tar.gz  file
        u-boot-dm6467t-evm.bin that I also pulled down from the above link

     

    Am I using the right files?  Am I supposed to be using DVSDK_2_00 or DVSDK_3_10 ?  The DVD that came with the board is titled "Digital Video Software Development Kit version 3.10.00.  And yet you are giving me a link to the 2.00 SDK.

    Also, the DVD has "TMS320DM6467T" printed on it.  What is the difference between the DM6467Tand the DM6467? Is our board DM6467T  How can I tell?

    If your board is DM6467T, you'd have seen (1080P EVM) printed on the board.

    If you don't see that, I'd suggest you not to use DVSDk3.1 but use DVDSk2.x because DVSDK3.1 is only supported for the DM6467T part; if you do see that, you can use the flash utility included in the DVSDk3.1 site as well we the DVSDk package itself.
