CCS/TMS320DM8148: Trying to Run Edma Example for DSP core of DM814x from EDMA LLD.

Hi Ammar,

Please share steps followed to connect to DSP, someone can help you on that if your missing any steps, I hope your using TI814.ccxml. When your running from slave core how are you choosing EDMA channels, It is possible that channels are occupied or programmed from other cores or linux itself and even the slots (param entries) might also be occupied or programmed by someone.

Hi Ammar,

DSP pll might not been enabled in u-boot may be , Please check in your u-boot "dsp_pll_config" is been called or not, If not please call that function and try attaching to DSP halting at u-boot console.

Function would look like below,

static void dsp_pll_config()
{
    pll_config(DSP_PLL_BASE,
            DSP_N, DSP_M,
            DSP_M2, DSP_CLKCTRL);
}

reset sequence for DSP you will find it in GEL file , it would look as below give some time between each command.
