Accessing DSP on OMAP3530 Beagleboard using JTAG

Michael Hallak-Stamler

Other Parts Discussed in Thread: CCSTUDIO, OMAP3530

Hi. I am new to this forum. I have a Beagleboard with Code Composer 3.3.82.13 (the latest) and a XDS510 USB+ JTAG emulator. I am able to connect to the ARM core OK but from what I read the DSP is powered down by default.

How can I power it up and start debugging DSP applications on the DSP core?

Thanks

There should be a omap3430_cortexA.gel file in your C:\CCStudio_v3.3\cc\gel folder that you can use in your CCS setup. This GEL file should give you an entry under the GEL menu of CCS on the ARM to run IVA22_GEM_startup(), running this GEL function should bring the DSP out of reset and let you connect to it.

Hi all,

Iam facing the problem while connecting target to XDS510 Parallel port plus
emulator, as I set the configuration to use OMAP3530 and beagle
board as target.

selecting XDS510 pp emulator and OMAP3530.

after this it is asking for router utility and GEL file for ICEPICK_C.

for this what i have to do and any one give me a procedure to connect the target with this XDS510pp emulator to beagle board in CCS3.3v.

Thanks in advance,
Vinay.

Vinay,

You do not have to specify GEL files for the icepick. But you should use the GEL file for the ARM as described by Bernie above. There is also a GEL file for the DSP. In my CCS install, they are in: C:\CCStudio_v3.3\boards\omap35xx_3430\gel

I am using CCSv4 and I run the the GEL scripts as required and I am unable to connect to the DSP core on the OMAP3530. I am using a Blackhawk USB560M emulator. I get the following message

Error connecting to the target:

Error 0x80000240/-1146

Fatal Error during: Initialization, OCS,

Invalid data was scanned by the emulation controller.

Verify the board setup to make sure the scan chain is properly

defined.

I had to set the JTAG CLK frequency to 10MHz and now it works.

Hello Angelo,

Were you able to connect to the DSP without using the ARM?

And how to change the JTAG CLK freq? I am using Blackhawk USB560bp.

-Thanks

Yes I have it working on the DSP.

Please see my attached file, rename it to .ccxml and it should work on Code Composer v4>

selecting XDS510 pp emulator and OMAP3530.

The XDS510PP emulator does not support the JTAG voltage of the OMAP3530 (1.8V), therefore you will have to get another emulator (XDS100v2, XDS510USB+, etc).

Best regards,

Rafael
