Syslink and Video Firmware Conflict

I am still running into issues with running this program. I modified my DSP platform as follows to match up with the prescribed EzSDK memory map but my program still crashes when video firmware is loaded. In searching the forum it seems the memory config for firmware_loader also needs to be modified? Is that the only other place where changes need to be made to run video firmware and the DSP? If not what other components need to be updated?

Thanks Lee, I will try these memory settings.

Are you using this definition with the 5.04 EzSDK?

Are you using this definition with the 5.04 EzSDK?

Yes, but I found that I needed to use the xdc and bios libraries from 5.03.  I'm using Syslink and Ipc from 5.04.

I made the changes and my app now runs with video firmware loaded, however when I quit the program and clean up I get these errors and have to reset the board in order to run my app again. Is this what drove you to 5.03 on XDC and BIOS?

VPSS_FVID2: contrl event 0x6 timeout
ti81xxfb ti81xxfb: failed to stop.
VPSS_FVID2: contrl event 0x6 timeout
ti81xxfb ti81xxfb: failed to stop.

No, my code will not build using the 5.04 xdc and bios libraries.  I haven't seen these errors before, I'm guessing that you are not correctly terminating Syslink.

I changed the area where I was putting my shared buffers to the area above 0x9F900000 and it seems to be behaving.

Thanks for the help.

hi ben, 

I am stuck in the similar issue here. Can you tell me, what changes you made in the platform.xdc. I believe you have a stand alone syslink application running, My platform points to the "ti.sdo.ipc.examples.paltforms.evmTI816X.dsp'

and here is the content of the file:

metaonly module Platform inherits xdc.platform.IPlatform {

config ti.platforms.generic.Platform.Instance plat =
ti.platforms.generic.Platform.create("plat", {
clockRate: 800.0, 
catalogName: "ti.catalog.c6000",
deviceName: "TMS320TI816X",
externalMemoryMap: [ 
["DDR_DSP", {name: "DDR_DSP", base: 0x8C000000, len: 0x02000000, space: "code/data",access: "RWX"}],
["DDR_SR0", {name: "DDR_SR0", base: 0x8E000000, len: 0x01000000, space: "code/data",access: "RWX"}],
],
l1DMode:"32k",
l1PMode:"32k",
l2Mode:"256k",
});

instance :

override config string codeMemory = "DDR_DSP"; 
override config string dataMemory = "DDR_DSP"; 
override config string stackMemory = "DDR_DSP";

}

Any help is appreciated.

Thanks

Here is the platform definition I used. Make sure you put the items you are passing from DSP to ARM somwhere in the SR1 region. At first I put them in the SR0 region and I got that vpss error I mentioned above.

    config ti.platforms.generic.Platform.Instance plat =

hi ben!

Thanks a lot, it works fine.. and i am able to run my application now..

best regards
