OMAPL-138 ARM+DSP Bootable Application

Jim Nalasco
Prodigy 70 points

Hi,

I've been working with the OMAPL-138 LogicPD SOM and have developed code for both the ARM and DSP. I would now like to create an SPI bootable version of code which is a combination of both the ARM and DSP code I've mentioned.

I've looked on the Starter Ware Wiki for a procedure or process that explains how to do this but at this point am still confused.

There are at least three support / utility applications mentioned: out2rprc, AISGen and the serial FLASH Writer.

If anyone knows the sequence of how these utilities should be used to create and install an ARM+DSP SPI FALSH Boot code can you please outline the process?

Also does anyone know if the code can be flased into the SPI FLASH using CCS and the Spectrum Digtial JTAG

Thanks!

    I have an identical requirement. And like Jim, I have the same level of confusion.

    The process of how to create a bootable image that contains both ARM code and DSP code is woefully indadequte.

    Looking through the bootloader sample code, it shows that it expects the ARM portion to be first, and the DSP entrypoint information to be second, as it scans through the entrypoint header information during the boot loading process. But how to glue those 2 images together is left as a mind-reading exercise. Also, must they both be in AISgen format, or just the ARM portion ?

    TI, please give us a little guidance here ...

    Thanks.
