Can't boot C6A8168 EVM board from SD card

song

Hi

I got a C6A8168 board From kind TI University program. But only main board without SD Card or mouse etc.

By using the EZSDK, I made a boot SD card which contains 

 

Next, according to the Quick start guide, 

http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/exports/C6A816x_AM389x_EVM_Quick_start_guide.pdf

I did the settings of SW3 and SW4 like these images, connected a UARRT, Ethernet cable, HDMI cable to a TV, 12V-DC power,

insert my SD card with boot files. But no mouse connected.

Finally When I power SW1 on, I got no response to UART, or HDMI TV.

The UART's setting is 

Port:       COM1

Baud rate:    115200

Data:         8 bits

Parity:       none

Stop:         1 bit

Flow control: none

Is there any wrong on the settings? Dose anybody experience this before ?

Because this board is new, I can't find much helpful information on the internet.

Your one word may be great help to me.

 

Regards

    Hi,

    Your switch settings look fine and verified it again on my board. Can you try with a different SD Card, possibly a different make?

    Hi Sid,

    Thank you for your kind reply.

    I tried different SD Cards, a new 2GB card and a new 4GB card.  They are formatted with boot files

    by EZSDK. But finally I got the same result

    I am not clear with your "different make". Is there any other make method other than

    host $ sudo ${EZSDK}/bin/mksdboot.sh --device /dev/sdb --sdk ${EZSDK}

    Insert SD card, power on/off, and on/off, after many times trying, only one time, the uart terminal gave out the a happy message like this

    then stopped. No other information like u-boot terminal can be found.

    All the files in my SD card are compressed to a rar file here:

    3731.boot.rar

    Could you please help try these files on your EVM Platform?

    If you can boot with these files successfully, I think there should be 

    something wrong with my EVM Board.

    By different make, I meant a different brand or manufacturer of SD card. The command that you are using is correct and it should generate the SD card correctly.

    I think there maybe a problem with your board that I may not be able to debug. Is it possible for you to get back in touch with local support to help with the board? The generated files look fine.

    Hi, I've meet the same problem on my EVM8168B(DM8168 with DDR3), there is no output on UART.

    Additional, I record the other UART which is for power moniter, the data printed are as following tables. I doubt if tthe board is something wrong.

    Normal 0 7.8 pt 0 2 false false false MicrosoftInternetExplorer4

    !Power Monitor

    #U14 (0V9)           0000912mV         0001000uA

    #U11 (1V8 A)         0001796mV         0001000uA

    #U7  (1V8 B)         0001820mV         0012000uA

    #U59 (VTT/1V5 ALT)   0001212mV        -0058400uA

    I am working on the DM8168 EVM DDR2 board, the error it shows is not the same as the one discuss before.

    I think you probably hookup to the wrong serial port, it should be the one behind the DDR2 memory

    not the one the left

    Can you please create a new post for this? We should not mix DDR2 and DDR3 issues in the same thread to avoid any confusion.

    Hi,

    Was this problem ever solved?  I am trying to bring the same EVM up and I am running into this issue as well.  I am not getting any output in the UART terminal and nothing over HDMI either.  I can see the power monitor output from the other UART when I plug into it.  I have followed all the directions given in the quick start guide, verified that the dip switches are set correctly, and tried a variety of SD cards in addition to the demo SD card.  Any ideas?

    regards,

    Patrick

    Hi all,

     

    This problem has been solved. TI changed me a new same board. Now It can boot up with the same setting of switchs and the same sd-card, which means the old EVM board must be something wrong that I can't figure out.
