CC3220S-LAUNCHXL: How to increase SPI drive strength

Part Number: CC3220S-LAUNCHXL
Other Parts Discussed in Thread: CC3220S

Hi,

I want to increase the drivestrength for SPI Clock on Pin 5. I see that you can do this by setting bit 7:5 of the GPIO_PAD_CONFIG_x register (page 587 of the Technical Reference Manual (TRM)). 

What I've done so far are:

1. Added the following in Board.h

#define Board_GPIO_P05                CC3220S_LAUNCHXL_GPIO_14

3. Added the following in the enum, CC3220S_LAUNCHXL_GPIOName of CC3220S_LAUNCHXL.h

CC3220S_LAUNCHXL_GPIO_14,

4. Added the following in gpioPinConfigs[] of CC3220S_LAUNCHXL.c

GPIOCC32XX_GPIO_14 | GPIO_CFG_OUT_STR_HIGH,

But there were no changes to the output. I have a feeling that this isn't the correct way to do it. Any help would be much appreciated :)
