ISR not in IRAM! and dont work

[kvvoff]

I have flashed the firmware, but when it starts up the LED is constantly flashing. I opened the port monitor and that's what it gives out. Google did not help me, I do not know what it is

ISR not in IRAM!

Abort called

And so in a circle constantly

[kvvoff]

On the other nodemcu board the same

[lebif]

Hi, same problem with all my board. Have you find solution ?

[kvvoff]

@lebif No friend, I never found a solution

[lebif]

Hi, @kvvoff, Solution is downgrade the esp822 board library to 2.4.2. (Arduino IDE go to board manager, esp8266 and install the 2.4.2 version.) Works fine !!

[petanque]

The developer says about 5.25 in his youtube video part 2 that you need version 2.3.0

[kvvoff]

@petanque thank you for info)

[reynolds087]

There are two functions in the .ino file that you can put this in front of them and it works on later version. It tells the compiler to keep the ISR function in memory and is required for ESP core 2.5.1 and later.

ICACHE_RAM_ATTR

example:

ICACHE_RAM_ATTR void dimTimerISR() {

[kvvoff]

@reynolds087 Thanks! I'll try

[nassir-malik]

Downgrade to ESP8266 2.5.0 library using Arduino board manager

[reynolds087]

@nassir-malik have you tried testing with the ICACHE_RAM_ATTR attribute on the two ISR functions? I believe this corrects the issues in newer library because I'm running your project on the latest version.

[nassir-malik]

Please downgrade ESP8266 support 2.5.0 in Arduino ide.

I did downgrade to 2.5.0 as suggested, but I can still see intermittent flickering.

What else could I be doing wrong?

@nassir-malik great tutorial. nodemcu getting connected to wifi but not connecting to MQTT error: INFO: Attempting MQTT connection... ERROR: failed, rc=-2DEBUG: try again in 5 seconds kindly help

Confirmed solution for me. Board: Wemos NodeMCU LoLin (Esp8266), I edited the file "robotdyn_dimmer.h" and changed the following: void zcDetectISR() to void ICACHE_RAM_ATTR zcDetectISR()

After that, it worked fine with the latest ESP8266 library. Oddly i didnt need to add "ICACHE_RAM_ATTR" to the other ISR function.

I will try it soon. Thank you
