Whenever the program encounters the above functions during execution, some of the LEDs & relays connected with GPIOs glow/toggle for a certain period of time and then turn-off automatically.
Why this is happening?
I'm storing 3 uint32_t data into eeprom which is working fine but why GPIOs are toggling.
Hi Alice_Yang
Not a demo board. Its a custom design. I have couple of GPIOs connected to leds and relays, all configured as active high.
Whenever a function related to eeprom write/read is encountered, these GPIOs turn off for 1 second and turn on again.
This is strange behaviour.
What could be happening?
Hello Gmk,
Could you please show the part of schematic about connecting LEDs & relays.
show which pins connected to them.

Hello Gmk9,
How do you config the GPIOs that connect to LED?
How about try the simple demo iap_eeprom under SDK package?
Hi Alice,
This is my GPIO configuration code
void alarm_fb_gpio_init(void)
{
IOCON->PIO[3][4]= 0x00000120;
IOCON->PIO[3][5]= 0x00000120; // Mains out of range
IOCON->PIO[3][6]= 0x00000120; // Emergency push button
IOCON->PIO[3][7]= 0x00000120; // Mains fail
IOCON->PIO[3][8]= 0x00000120;
IOCON->PIO[3][9]= 0x00000120;
IOCON->PIO[3][10]= 0x00000120;
IOCON->PIO[3][11]= 0x00000120; // Backdoor-1 open
IOCON->PIO[3][12]= 0x00000120; // Backdoor-2 open
IOCON->PIO[3][14]= 0x00000120; // Spare-1
IOCON->PIO[3][15]= 0x00000120; // Spare-2
// Set as input pins
GPIO->DIRCLR[3] |= (1<<4) | (1<<5) | (1<<6) | (1<<7) \
| (1<<8) | (1<<9) | (1<<10)| (1<<11)\
| (1<<12)| (1<<14)| (1<<15);
CLOCK_EnableClock(kCLOCK_Gpio5);
// GPIO for Doors open buzzer indication
IOCON->PIO[5][0]= 0x00000120;
// Set as output pin
GPIO->DIR[5] |= (1<<0);
// GPIO for Doors open buzzer indication
IOCON->PIO[5][1]= 0x00000120;
// Set as output pin
GPIO->DIR[5] |= (1<<1);
}
I didn't check with demo. I'll check.
Hello Gmk9,
How about your this case now?
Please contact me without any hesitate if still have question.
Regards,
Alice
