Starterware/OMAP-L138: gpio_armv5 omapl138 does not work with xds200 probe...

Tool/software: Starterware

Hi All

I am new to this development platform. I have installed ccs and the starterware OMAPL138_StarterWare_1_10_04_01.

Then,

1/ import the gpio_armv5_omapl138_lcdkOMAPL138 demo.

2/ change the project variant to LCDKOMAPL138 and connection to Texas Instruments XDS2xx USB probe.

3/ compile and get error about memory map overlay

4/ delete the original cmd file and retain the OMAPL138.cmd file

5/ compile error free

6/ run debug error free

7/ start the program that appears to work ok turning 109 on and off. see below:-

/* The Local PSC number for GPIO is 3. GPIO belongs to PSC1 module.*/
PSCModuleControl(SOC_PSC_1_REGS, HW_PSC_GPIO, PSC_POWERDOMAIN_ALWAYS_ON,
PSC_MDCTL_NEXT_ENABLE);

/* Pin Multiplexing of pin 12 of GPIO Bank 6.*/
GPIOBank6Pin12PinMuxSetup();

/* Sets the pin 109 (GP6[12]) as input.*/
GPIODirModeSet(SOC_GPIO_0_REGS, 109, GPIO_DIR_OUTPUT);

while(1)
{
GPIOPinWrite(SOC_GPIO_0_REGS, 109, GPIO_PIN_LOW);

Delay(1000000);

GPIOPinWrite(SOC_GPIO_0_REGS, 109, GPIO_PIN_HIGH);

Delay(1000000);
}

8/ The problem is that the physical LED does not respond. 

9/ if I repeat with the C674x version it works fine. 

Any suggestions would be greatly received.
