Problems with generation of AIS from tutorial

Pawel Pyszko

Other Parts Discussed in Thread: OMAP-L138

I was trying to build AIS for DSP from this tutorial: http://wiki.tiprocessors.com/index.php/Boot_Images_for_OMAP-L138

In short - I don't even compile in CCS to .out files to avoid generation of more opportunity to make mistakes. So I'm loading .cfg file for UART2 mode and 2 .out files from example's .zip then just using UART Boot Host to load Image to target but it doesn't work. Should I add some configuration options in AISgen because it just sets PSC:15 and UART transsmition speed.

Hi Pawel, are you using the EVM or a custom board?

I'm using eXperimenter Kit from LogicPD, but that's not a problem because I once did it sucessfully, but I can't any more.

If you flash the "OMAPL138-DSP-LED-NAND-SPI-UART.bin" file that comes in the package does that work? Or is your issue only when creating the AIS from the .out files?

It works with included .bin. Problem is when I'am creating. Like I said: I'm fallowing instruction:

1.Loading configuration for UART

2. Adding first .out, then using "+" button adding second .out

3. MAking .bin file

Hi Pawel, I just checked it out and the latest version uploaded did have an issue. The DSP and ARM were using the same shared memory locations, so the ARM code was getting overwritten. It has been corrected now by changing the linker.cmd files, and the new version is on the wiki. Please try it out. Thanks

Ok, now it is working fine. Thanks for intervention Jeff.

My next move is to start examples for DSP from CCSv3 with ARMs .out file from this tutorial. Is it hard? What should I do? .Out files from this examples without any change doesn't work.

I'm not sure I understand. The current example runs the blinking program on the DSP, so you should be able to modify the DSP code if you want to change the example. See the notes in the wiki about setting your entry point to match the one the ARM is setting the DSP reset vector to.

Yeah, I'm, but I want to be able to edit one of the TI example from ccsv3 directories because there is more functions. I will check entry point setting like you suggested.
