GPIO Configuration as Output not working with PSP

Other Parts Discussed in Thread: OMAPL138

Hi,

I'm using the following tools:

- CCSv5

- PSP 01.30.01

- DSP/BIOS 5.41.11.38

- EDMA3 01.11.03.01

I started with the PSP included GPIO example which has the GPIO4[0] setup as Input. I was able to build this example and ran it successful. Now I was trying to modifiy this example to toggle an another pin as output, GPIO2[0] - but this fail and at the moment I don't know why..

See the code i used below:

#define GPIO_BANK_2               2u
#define GPIO2_0_PIN                 33u

sysRegs->PINMUX6 = ((CSL_SYSCFG_PINMUX6_PINMUX6_31_28_GPIO2_0) << (CSL_SYSCFG_PINMUX6_PINMUX6_31_28_SHIFT));

/* lock the pinmux registers                                              */
sysRegs->KICK0R = 0x00000000;
sysRegs->KICK1R = 0x00000000;

gpioParams.instNum = 1;
gpioParams.BankParams[GPIO_BANK_2].inUse = Gpio_InUse_No;
gpioParams.BankParams[GPIO_BANK_2].hwiNum  = 8u;
gpioParams.BankParams[GPIO_BANK_2].PinConfInfo[0].inUse = Gpio_InUse_No;

/* open the GPIO driver to get a handle to it */
gpio1 = Gpio_open(&gpioParams);

PWRM_setDependency(PWRM_RSRC_GPIO);

/* Configure GPIO(GPIO2_0_PIN) as an output                                */
pinCmdArg.pin   = GPIO2_0_PIN;
pinCmdArg.value = Gpio_Direction_Output;
Gpio_setPinDir(gpio1, &pinCmdArg);

pinCmdArg.value = PinVal;
Gpio_setPinVal(gpio1, &pinCmdArg);

while(1)  
{       
PinVal = !PinVal;       
pinCmdArg.value = PinVal;      
Gpio_setPinVal(gpio1, &pinCmdArg);      
TSK_sleep(2000);
 }

 What I'm doing wrong here?

Maybe, has anybody an working examplecode for this? 

Thanks a lot for your help in advanced
