AIS Parser

Other Parts Discussed in Thread: OMAP-L138

Fair warning, I do not have a Linux host so whatever solution you have for me needs to be extractable or executable on a Windows machine.

I am looking for source code that shows an example of AIS parsing. I was just going through E2E and I see one mention of an AIS parser:

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/99/p/6353/24011.aspx#24011

I am then guessing that this would exist for the OMAP DVSDK 4 as well but it is only available for Linux hosts? The last time I needed anything from there I had to get the FAE to zip up that part of the SDK and FTP it to me. I'm hoping we can avoid this as the FAE is currently traveling.

Any idea where I can find something similar to the flashutil so I can use that AIS parser source? (i.e. C:\dvsdk_1_11_00_00_DM648\flashutil\DM647_8\CCS\UBL\src)

I am going to copy the parser into my own code so it is not necessary to get a project that compiles on my Windows machine. I simply need the source code.

I don't believe a stand-alone AIS Parser was created for the OMAP-L138.

I looked around and found something similar in the UartHost deliverable, that comes with the bootloader appnote. Inside the UartHost folder, there is a C# source code for parsing some of the AIS commands. You can probably use this as reference in creating your custom AIS Parser.

Alright, I think I've found what you are alluding to. I went to the following website:

http://processors.wiki.ti.com/index.php/Serial_Boot_and_Flash_Loading_Utility_for_OMAP-L138

On there is a title called "Obtaining Software"

Once you download and extract those contents you need to go to:

C:\OMAP-L138_FlashAndBootUtils_2_29\Common\AIS

Within that folder you will find AISParse.cs as well as AIS.cs (besides other AIS-related files). This example I can try to convert from C# to C to create my own custom AIS Parser. Does that sound like what you were talking about?

The one that I found was from the Using the OMAP-L1x8 Bootloader Application Report zip file, http://www.ti.com/litv/zip/sprab41c. When you install that, there's a file called AIS_Util.cs in the UartHost folder.

You found another version too. Hopefully, both of these resources will help you.

Ah yes, I see it now as well under C:\Program Files\Texas Instruments\AISgen for D800K006\UartHost

This will be a good starting point at least. Thank you. I'll mark you as verified. You should mark me as verified as well. How else can I make it to Expert level? ;-)

Does anyone have a Microsoft Visual Studio solution or project set up for that that includes the GUI resource?

FYI some python scripts for AIS parsing and generation.

Definitely a work in progress, but you may find them useful. Feedback appreciated.
