Hi, I am now working on how to make use of the DSP(Tesla) on my OMAP 4430 based pandaboard. When I am building bios-syslink, download from:
It is always error to build for the C64T option:
This is the error message
configuring ti_omap_platform_dsp/whole_program_debug/Notify_Test_Dsp.xe64T from package/cfg/ti_omap_platform_dsp/whole_program_debug/Notify_Test_Dsp_xe64T.cfg ...Tesla Power Mgmt = OFFUnicache = OFFjs: "/home/ju/omap_data/omapts/linux/dsp-tc/bios_6_31_03_25/packages/ti/sysbios/family/arm/ducati/package.xs", line 72: Error: Library not found: ti.sysbios.family.arm.ducati.ae64T
build tool: C6000CGT 7.2.0 BIOS 6.31.03.25 TMS470CGT 4.6.1 xdctools.3.20.07.86
And I have changed suffix of /bios-syslink/package/ti/omap/deh/Deh_wdtIsr.asm to Deh_wdtIsr.sa, that thing been also been changed in package.bld to avoid the assembly error.
If someone has build Tesla for bios-syslink, please help me. Thank you very much
Please take a look at this page on the omappedia, which contains instructions on how to build Syslink/RPMsg for the DSP: http://omappedia.org/wiki/RPMsg_Tesla

Thank you for your reply.
I have tried RPMsg_Tesla in my PC. When I try to build for "C64T", no error happens, but I still cannot get the tesla-dsp.bin mentioned in http://omappedia.org/wiki/RPMsg_Tesla
I find it in the white paper that OMAP 4430 has a programmable DSP. But yet I am still not clear how to make use of this dsp. I just want to use this dsp to do some computer vision project, is it possible to do dsp programming in omap 4430?
Thank you very much!
in the RPMsg_Tesla for syslink there is next note, default selected label is not latest or required when download using git clone
"Note: Make sure you use tag 1.10.04.12 or beyond. Before this tag there is no Tesla Support."
by using next command you can check what labels exist,
$ git tag
I just build successfully the Tesla imagen and I see the images. What I did was to follow the steps in the wiki:
1) Download sysbios-rpmsg code
2) Download tools setups
3) create the dir path /data/omapts/linux/dsp-tc/cgt6x-7.2.0
4) Run the CGT setup and set the path /data/omapts/linux/dsp-tc/cgt6x-7.2.0
5) Run the other setups setting the path /data/omapts/linux/dsp-tc/
6) Export the variables and build
It has finish without any issue.
About the other question, yes it is possible to make programming in there, you may want to look into the samples in the sysbios-rpmsg code, there are some samples that create some task to run in the DSP.
Thank you for your advice. I have just build the image for Tesla. I forgot to check the tag version. Thank you very much
Thank you for your advice. I have just build the images for Tesla. I will look deep into the codes and learn to do the dsp programming. Thank you very much!
