User Init & Dvsdk problems?

Hello,

I have 2 identical boxes running with a DM648 DSP hosted by a PowerPC processor via the PCI port.  One Box runs the DM648 with a DSP/Bios (v5.41.02.14) Application only, and another box runs a DSP Application with both a DSP/Bios (v5.41.02.14) Application using the DM648 dvsdk (dvsdk_1_11_00_00_DM648) psp drivers. The PowerPC Host sets up the PSC Controller identically on both boxes as well.

I have specified a User Init Function in the DSP Bios for both applications in the .tcf file, and it is shown below.  This code works fine with the DSP/Bios only application, but the DSP Peripherals get into a strange state and will not initialize with the DSP running the DSP/Bios with dvsdk psp drivers.  Why is there a problem with the dvsdk version of our application?

The User Initialization code is as follows:

void UserInit(void)
{
 
    setPSCModuleState(PSC_UART, PSC_DISABLE);

    // Disable Modules
    setPSCModuleState(PSC_VP2, PSC_DISABLE);
    setPSCModuleState(PSC_EDMACC, PSC_DISABLE);

    // Enable Modules

    setPSCModuleState(PSC_VIC, PSC_ENABLE);
    setPSCModuleState(PSC_GPIO, PSC_ENABLE);
    setPSCModuleState(PSC_I2C, PSC_ENABLE);
    setPSCModuleState(PSC_PCI, PSC_ENABLE);
    setPSCModuleState(PSC_EDMACC, PSC_ENABLE);
    setPSCModuleState(PSC_VP2, PSC_ENABLE);
    setPSCModuleState(PSC_MCASP, PSC_ENABLE);


    //Turn Off unusued Modules

    // Turn Off Ethernet Subsystem
    setPSCModuleState(PSC_ETHERNET, PSC_DISABLE);

    return;

}

and for your info, SetPSCModule State is shown below (same code as found in DM648 .gel file):

Uint32 setPSCModuleState(Uint32 module, Uint32 state)
/* Changes the module state within the PSC, based on the value
   0 = SwRstDisable          1 = SyncRst      2 = Disable       3 = Enable  */
{
    volatile Uint32 *ctl_addr;
    volatile Uint32 *stat_addr;
    volatile Uint32 *cmd_reg;

    Uint32 lrst = 0x0l;

    /* Set Local Reset Variable */
    if (module != PSC_C64PLUS_CPU)
    {
        lrst = PSC_LRST;
    }

    /* set next state for module  */
    stat_addr = (Uint32 *)(PSC_MOD_STAT_REG_BASE + (module * 4)); 
    ctl_addr = (Uint32 *)(PSC_MOD_CNTL_REG_BASE + (module * 4));
    *ctl_addr = ((*ctl_addr & 0xFFFFFE00) | state | lrst);

    /* evaluate next state for given power domain - 'GO' */
    cmd_reg = (volatile Uint32 *)(PSC_PTCMD_REG_BASE);
    if (module < PSC_ETHERNET)
    {
        *cmd_reg = PSC_GO0;
    }
    else
    {
        *cmd_reg = PSC_GO1;
    }

    /* poll transition status for completion */
    //while (((*(int *)stat_addr & 0x000001F) != state) & (*(int *)PSC_PTSTAT_REG_BASE != 0x0));
    while (*((volatile Uint32 *)PSC_PTSTAT_REG_BASE) != 0x0);

    return ((*stat_addr) & 0xf);

}
