Hi!

Just wanna know which demos included in the OMAPL138_StarterWare_1_10_04_01 are easy to observe when running? Such as some LED blinking? Is there a gpioled demo? Couldn't find it .....

What is your board ?
Custom or LogicPD EVM or LCDK board ?

Please refer to the following starterware installed location.
C:\ti\OMAPL138_StarterWare_1_10_04_01\examples\lcdkOMAPL138\gpio\gpioCardDetect.c

LCDK
I looked into the gpioCardDetect.c and got this :This is a sample application file demonstrating the use of
* a GPIO pin to generate an interrupt whenever an MMC/SD card
* is inserted or ejected from the Evaluation Module(EVM).
So what would happen when I run the demo and inserted/ejected the SD card? Is the GPIO pin is linked to a LED? Can I observe something when the interrupt happens?
Thanks!

And one more small question, after I flashed the demo into the LCDK under UART2 mode, I need to repower the board and boot from NAND mode, right?
So ,which one should I use, NAND 8 or NAND16?
I'm a little confused by all kinds of boot modes and the switch sets around. Is there a sheet or something gives the switch settings of all the boot modes exactly for the LCDK?
Sorry for so many problems, just getting started...

Hi Neal,

When you will insert a SD Card , an interrupt will be raised and you will observe a message("MMC/SD Card Inserted ")on your serial console.

The explanation is given wrongly.
It will blink the LED.

LCDK board using NAND16 data width.

Thanks a lot, it works!

The code would blink the LED D4.

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

Delay(1000000);

GPIOPinWrite(SOC_GPIO_0_REGS, 109, GPIO_PIN_HIGH);

Delay(1000000);
}

Please refer to the OMAPL138 TRM (page no 108) and LCDK schematics.
