Board rebooting

[eried]

Hi! this is a great board idea thanks! I am having some issues running anything on it, normal examples run ok, but trying ESP-12S_A9G_GET_GPS I get a constant reboot:

OK
ISR not in IRAM!

User exception (panic/abort/assert)
Abort called

After 2s A9G will POWER ON.

I am using a 3.7 battery that was charged to 3.9V:

Any suggestion?

Hi,
Maybe have 3 way to solve this problem.

1. Block out the interrupt function if you not use this function.
   //pinMode(A9G_WAKE, INPUT);//interruptPin
   // attachInterrupt(digitalPinToInterrupt(A9G_WAKE), handleInterrupt, RISING);
2. Refer here: https://github.com/IOT-MCU/ESP-12S-A9-A9G-GPRS-Node-v1.0/wiki/3.Using-Arduino-IDE

Please select the 2.5.0 version of esp8266 URL.

3. According to the new version of arduino, redefine the interrupt function.

Thanks! I will test tomorrow

So, it works commenting

//pinMode(A9G_WAKE, INPUT);//interruptPin
// attachInterrupt(digitalPinToInterrupt(A9G_WAKE), handleInterrupt, RISING);

With latest version 2.7 of ESP8266 firmware :)

Same issue, and same solution: commenting out the interrupt function.

[sadamyne]

The solution is to add ICACHE_RAM_ATTR to your handleInterrupt function:

ICACHE_RAM_ATTR void handleInterrupt() {
}

Great! Thanks sadamyne
