CCS/OMAP-L138: blink not working when imported as a task in SYN/BIOS

Part Number:OMAP-L138

Tool/software: Code Composer Studio

Hi All

1/ I have a led blink example working on the ARM core in regular C.

2/ I have now created a new project in syn-bios project and have created a task with the working code. It compiles error free but produces the following error

i.sysbios.family.arm.exc.Exception: line 205: E_dataAbort: pc = 0xc3004974, lr = 0xc300cf04.
xdc.runtime.Error.raise: terminating execution

3/ From what I can tell there is some issue accessing hardware functions from a task. specifically:- 

3.1/ PSCModuleControl(SOC_PSC_1_REGS, HW_PSC_GPIO, PSC_POWERDOMAIN_ALWAYS_ON, PSC_MDCTL_NEXT_ENABLE);

3.2/ savePinmux = (HWREG(SOC_SYSCFG_0_REGS + SYSCFG0_PINMUX(13)) & ~(SYSCFG_PINMUX13_PINMUX13_15_12));

HWREG(SOC_SYSCFG_0_REGS + SYSCFG0_PINMUX(13)) = (PINMUX13_GPIO6_12_ENABLE | savePinmux);

3.3/ GPIODirModeSet(SOC_GPIO_0_REGS, 10, GPIO_DIR_OUTPUT);

There is obviously something that I need to know that can not be found in other examples. Can any one supply a program that blinks a LED on the ARM core in the SYN Bios environment?

Any advice would be greatly received.
