CSL HS USB

Other Parts Discussed in Thread: TMS320C5515

Hi,

Is there any real-working example of HighSpeed USB in C55xx ?

Either Iso or Bulk would suffice for me, in whatever application they exhibit, plain EP packet data or Audio or MSC or anything, provided that it is in HighSpeed.

I've seen the v4 in csl_usb_iso_highspeed example but the sources themselves mention that it is not working.

 

Thanks,

Christos

    Hi Hyun,

     

    I'm interested in TMS320C5515,

    I have a TMDX5515EZDSP board and trying to implement a High speed solution but I couldnt find any example yet.

     

     

    Regards,

    I'm in real need of a highspeed USB example with TMDX5515EZDSP (TMS320C5515 eZDSP USB STICK).

     

    I tried the new CSL_55xx DMA USB example

    TMS320VC55XCSL-LOWPWR\c55xx_csl\ccs_v4.0_examples\usb\CSL_USB_DmaExample

    but it does not even enumerate on the USB bus.

     

    There was a suggestion that the TMS320VC55XCSL-LOWPWR was targeted to the EVM55x5 thus due to schematic differences to C5515eZdsp the examples did not apply.

    I did checked the two schematics and specifically on the USB part that interests me but I could not find any differences so the assumption is that this example should work ok on C5515eZdsp but yet again it does not as it has been found.

     

    So please, anyone from TI to help here regarding a USB DMA/Highspeed example on C5515eZdsp, or at least to assist on what the difference is in the USB circuitry that I might miss in between EVM5515 and C5515eZdsp.

     

    Thanks for any answer,

    Christos

    Ok,

    Everything is fine now, I just reinstall everything (did CSL modifications) and it worked.
