load and start dsp application with SysBios

Other Parts Discussed in Thread: OMAP-L138, SYSBIOS

Hello,

I'm using an OMAP-L138 and try to run SysBios on ARM and on DSP side. My aim is to load different DSP (and ARM) images over TFTP, depending to the detected HW.
But so far, I couldn't find a way to load and start a DSP application from the ARM side running SysBios.
For Linux there is SysLink, which covers this topic, but what can I use for SysBios?

Best regards

Hi Stéphane,

In SysBios, there is currently no 'loader' similar to what ProcMgr in Syslink does, which is probably the reason for the lack of response to this thread. However, I have come across one lab example from the Training Organization's BIOS workshop which combines the ARM and DSP executables into one single bootable binary file that can then be flashed. The ARM and DSP images are copied into RAM at run-time. All the ARM side application would have to do then is to start/wake up the DSP, which is also shown in the example. I have not tried this example myself, but maybe it will help you along.

Link to the workshop:http://processors.wiki.ti.com/index.php/C6000_Embedded_Design_Workshop_Using_BIOS

The lab files (rev 6.25) are posted on the workshop page.

Check out the "Booting from Flash" section found in this document:

http://software-dl.ti.com/trainingTTO/trainingTTO_public_sw/bios/SYSBIOS_Workshop_Student_Guide_Rev6_25.pdf

It contains the lab instructions that walks you though the steps to do this. Perhaps you'd find it useful to go through it.

Best regards,

Vincent
