Contents after JUMP_CLOSE in AIS

Anonymous

Hi,

I would like to ask a question on AIS.

On page 21 of SPRAAG0D, Using the TMS320DM643x Bootloader, it is said that JUMP_CLOSE signals the end of AIS script. If this is the case, why would there still be

1. Total Number of Sections to Load

2. Total Number of Bytes of Code/Data to Load

after the JUMP_CLOSE command? What is their utility? Would they be executed at all?

BTW, is this the right forum to ask questions on booting and AIS?

If you look at the details section of the jump close command on page 25, I think you will find the answer to your question. As to the utility of those entries, they are probably more for a quick reference than anything else.

I have no idea on this and don't know why it is appended.

Have you ever used AIS? Do you write it manually or generate it using GenAIS?

I have used AIS for a NOR flash fast boot. I'll try to dig up the exact tools I used, I want to say it was a utility called hexAIS (?) but I can't remember it's been so long ago. I remember the documentation back then was not very helpful (I had the original version of spraag0 on my hard drive and had to download rev D).

Matt,

I googled and found this GenAIS GUI tool. I guess that the HexAIS you used is a command line utility? And this GenAIS is probably an GUI interface of that?

Could any TI employee confirm on this?
