DSPLink known issues
Affected Release Bug found on Date Bug Headline Affected platform Affected OS Workaround if any Release with fix
1.64 Dec 2009
  • Runtime configuration of DSP clk is incorrect for the following platforms:DM6467, DM6467T and OMAP3530
  • DM6467
  • DM6467T
  • OMAP3530


Two possible workarounds (though see this forum post which implies workaround #2 is correct):

  • Workaround 1 - Update DSP application code:- Add a GBL_setFrequency(GBL_getFrequency()/1000) after the call to DSPLINK_init in main in the DSP side code in the DSP application
  • Workaround 2 - Update DSPLink code
    • DM6467/DM6467T users - Update function DM6467GEM_getDspClkRate in $DSPLINK/gpp/src/arch/DM6467GEM/shmem/Linux/dm6467gem_dspclk.c
  *cpuFreq = (clk_get_rate (clk) /1000) ;
    • OMAP3530 users - Update function OMAP3530_getDspClkRate in $DSPLINK/gpp/src/arch/OMAP3530/shmem/Linux/omap3530_dspclk.c
  *cpuFreq = (clk_get_rate (clk)/1000) ;
  • Re - Build DSPLink GPP code
  • Use updated DSPLink kernel module
  • 1.65 (Planned) Jul 2010
  • Incorrect Release Notes in Linux package dsplink_linux_1_65_00_03
  • All platforms based on Linux


Workaround: See attached release notes File:ReleaseNotes.pdf

  • 1.65 (Planned)
