C6A816x/AM389x EVM

Hi,

few weeks ago I received theC6A816x/AM389x EVM board.

I followed what is written in documentation, I used the SD card within the pack, I configure the board to boot from SD,

but I haven't got any result.

I when I boot from the SD CARD, with the sd supplied, after few moments, I can see the DDR turn on, the clock begin to run at 400 Mhz,

and begin the activity on the RAS and CAS signals. This actitvity seem be refresh cycles of memory, I didn't see any activity similar to read and write on memory.

I cannot see any string appearing on the serial port.

I tried to download the first stage boot from TFTP and I got the same result, same activity on SDRAM after the download.

 

Anyone has the same problem on the board?

 

Best regards,

Giacomo.

    Giacomo,

    I hope you have already checked your SD card on the PC to verify all the content. You can re create another SD card with the installer provided in the SD card on your Ubuntu setup.

    If your SD card has no content then you can download the new SDK package from http://software-dl.ti.com/dsps/dsps_public_sw/ezsdk/latest/index_FDS.html

    I think your boot settings are correct for SD card. But to cross check you can remove the NAND chip and again boot from SD card without NAND.

    Hi Hasheesh,

    I checked the SD and seem to be ok, there is the MLO file.

    I made a new SDCARD with the script you provide on the sdk, and with this, I got the same result.

    Looking with scope, I can see the loading of the MLO code from SDCARD, after few millisecond, I can see the begining

    of the clock on DDR dram, and the begining of the activity on the RAS and CAS signals.

    When I download the MLO from a TFTP server I got the same result.

     

    Any other Idea?

     

    Regards,

    Giacomo.
