Request for Custom Design Clarification- ADV7282AWBCPZ-M

Hi,

  Please find the below response for your queries,

 1).  External flash is required only based on your code size.

     Your approach is enough for running the ADV728x I2C script configuration i.e  A two-pin header for both SDA and SCLK. This will be used for flashing the ADV7282AWBCPZ-M from an external host like an Arduino or Raspberry Pi.

2). We cannot guarantee the performance unless you follow our specifications.

3). Regarding DIAG connection, Please refer (1) [ADV7281-M] There is difference between Figure 13 and Figure 21 on the datasheet about connection of DIAG pin. - Q&A - Video - EngineerZone

   (1) [ADV7281-M] The circuit arround DIAG pin. - Q&A - Video - EngineerZone

4). We can use DVP EVAL latest source software for programming the ADV7280A. The installation guide of ADV7280A describes how to program the board using DVP software. You can refer that in following link 3034.ADV7280installationguideRevA.pdf

      Kindly check the DVP eval software limitation at https://ez.analog.com/video/w/documents/767/dvp-evaluation-software

Hi,

Thanks For Your Response.

Please confirm the below queries.

• Should I use the same program [Evaluation Board Program] for the new ICs also? There's no need to modify anything, right, since we only have two analog single-ended inputs? Or do we need to make any modifications for these types of hardware changes?

• If the evaluation board script file is sufficient, we don't need any external flash, right? The ADV7282AWBCPZ-M itself should be enough to store this script file program, correct?

• Additionally, I referred to the reference design you suggested in the previous reply, and there is no circuit for power delay. In that design, 3.3V and 1.8V are derived directly from 7.4V. In our case, we have a 3.3V output regulator, and from the 3.3V output, we generate 1.8V. Therefore, 1.8V powers up only after 3.3V. This power sequence should be sufficient, right?

Please find the attached circuit diagram. kindly review and share your comments.

Hi,

  1) Yes you can use the same program, For running the script Please refer section 2.3 at 3034.ADV7280installationguideRevA.pdf

  2) Yes, ADV728x part is enough for running the script and this external flash is required based on your software support. 

  3) Yes, your power sequence is right,1.8V powers up only after 3.3V.

     As per expert comment "Basic rule to follow is that the 1.8V rail cannot exceed the 3.3V rail. This applies to both power up and power down sequences. 

Thanks,

Hi,

    Please crosscheck your circuit against our reference schematic at ez.analog.com/.../1803.ADV7280_5F00_MSchematic.zip

    Reference (+) ADV7280 / ADV7280-M Design Support Files - Documents - Video - EngineerZone

Hi,

I designed the circuit based on this reference schematic only, but it would be very useful if you could review it and share your comments.

Additionally, if you need any more information, I will share it.

Hi,

I have gone through the document(3034.ADV7280installationguideRevA.pdf). Using filezilla, I tried to connect with the server from my local system. But it could not connect with the ADI FTP site.

I followed the procedure from the document only. I have the shared the received log from filezilla. Please review and tell me the suggestion.

NOTE1: We chose the ADV7282A series, but you sent all the links and documents for the ADV7280 series. Kindly confirm whether the procedure is the same for both ICs.

Hi,

 Please try to set up the FileZilla in below way,
    Change FileZilla Site Manager -> General tab -> Encryption from "Use explicit FTP over TLS if available" to
"Only use plain FTP (insecure)" allows FileZilla to work with our FTP server.
Reference : (3) [ADV7480] Filezilla FTP client connection failure - Q&A - Video - EngineerZone

Please note that when you order EVAL-ADV7282A eval board, you would receive a piece of paper explaining about how to log in to our FTP site and downloading the register control software for this board.
In this pdf they have provided the details of downloading and installing the DVP Eval software,
 3034.ADV7280installationguideRevA.pdf. 
Also Please install file zilla from https://filezilla-project.org/FileZilla

Hi,

Apologies for the delayed response.

Thank you for providing the procedural steps. I have downloaded the files and attempted to run the ADV7282M script. However, in the evaluation board software application, it shows "Board Disconnected."

I have connected the CH341A programmer and the custom ADV7282M board via the I2C interface to the software application. Please review and confirm my interpretation below:

Is this application only compatible with the evaluation board?
How can I configure or run the script for the ADV7282M custom board?

I would appreciate your response at the earliest.

Regards,
Nitheesh

Hi,

Could you please give the response as soon as possible?

Hi,

  Please refer this thread (+) EVAL-ADV7280A-M No I2C communication - Q&A - Video - EngineerZone and here customer resolved the problem after following some procedure.

Thanks,

Poornima

Hi,

Thanks for response.

I have gone through the forum and tried the procedure. Still, It is Board Disconnected.

How to resolve this issue?

Note:- we are using custom board having adv7282-m. We have connected the converter which is CH341a programmer. 

Connection details
PC(Eval software) connected with Custom board through  i2c interface by CH341A programmer.
