Blimp cannot connect to Blackfin OR ADV7625

Hi everyone,

I have an EVAL-ADV7625-SMZ board.  I have been able to successfully connect to it and read/write individual registers using AVES Blue.

AvesConnection_1

AvesConnection_2

My main goal is to get an HDMI overlay with some basic text.  Even "Hello World" in the bottom corner will do just fine.

When I create a basic project in Blimp and try to flash the EVAL board using one of the two Flash options, I get the following results.  Can someone give me any pointers?

Thankyou!

    Hi,

    Our ADV7625 evaluation board comes programmed with a software driver which has in built OSD data in internal flash. So there is no need to flash the OSD data as it is already programmed.
    And also When using the ADV7625 evaluation boards, We recommend customer to use our software driver, not scripts.Here's the support page Advantiv EVAL-ADV7625-SMZ Video Evaluation Board.. You can see the software package source code download link there. Please go to the ADV7625 ADV7626 ADV7627 evaluation board software package documents and refer document Advantiv_CrossPoint_Application_Userguide_Pr1.5-2.pdf APPENDIX added for the steps of OSD Integration in to HDMI software.

    When using EVAL-ADV7625 SMZ platform. Please press SW5 switch after power up the board and check you have the BF USB connection is changed as like attached (Right side) and then try to flash the binary using Blimp tool.



    Note:User can configure either in external flash or internal flash memory.
    External flash memory: The OSD data will be stored in ddr2_dump_raw.bin file under the relaese folder.This binary file needs to be flashed using blimp tool either by using USB or UART.
    Internal flash memory: The OSD data will be stored in data memory.No need to flash the binary file. So you need to integrate OSD into HDMI Software.

    Thanks,
