ISR not in IRAM error

AdamAnt

Hello,
I'm trying to setup an ESP8266 (bare ESP-12E) based gateway using the RFM69 radio module.
However when I start the gateway, I get the error message ISR not in IRAM

I'm using mysensors 2.3.1, with versio 2.5.2 of the ESP8266 board library.

I'm wiring it up to an RFM69W exactly as in the wiring diagram on the Connecting the Radio page, with the exception of NSS being connected to pin 5 not 15.
The power supply I'm using has more than enough headroom, its a bench supply and shows about 60mA pulled at startup.

My gateway sketch & serial output is below.

Any ideas greatly appreciated!!

SDK:2.2.1(cfd48f3)/Core:2.5.2=20502000/lwIP:STABLE-2_1_2_RELEASE/glue:1.1-7-g82abda3/BearSSL:a143020

 * DESCRIPTION
 * The EthernetGateway sends data received from sensors to the WiFi link.
 * The gateway also accepts input on ethernet interface, which is then sent out to the radio network.
 *
 * VERA CONFIGURATION:
 * Enter "ip-number:port" in the ip-field of the Arduino GW device. This will temporarily override any serial configuration for the Vera plugin.
 * E.g. If you want to use the default values in this sketch enter: 192.168.178.66:5003
 *
 * LED purposes:
 * - To use the feature, uncomment any of the MY_DEFAULT_xx_LED_PINs in your sketch, only the LEDs that is defined is used.
 * - RX (green) - blink fast on radio message received. In inclusion mode will blink fast only on presentation received
 * - TX (yellow) - blink fast on radio message transmitted. In inclusion mode will blink slowly
 * - ERR (red) - fast blink on error during transmission error or receive crc error
 *
 * See https://www.mysensors.org/build/connect_radio for wiring instructions.
 *
 * If you are using a "barebone" ESP8266, see
 * https://www.mysensors.org/build/esp8266_gateway#wiring-for-barebone-esp8266
 *
 * Inclusion mode button:
 * - Connect GPIO5 (=D1) via switch to GND ('inclusion switch')
 *
 * Hardware SHA204 signing is currently not supported!

@adamant According to this post: https://community.blynk.cc/t/error-isr-not-in-iram/37426/15
could you try the following:

For the old RFM69 driver (you seem to be using this one):
Change the following line https://github.com/mysensors/MySensors/blob/development/hal/transport/RFM69/driver/old/RFM69_old.cpp#L464
from

void RFM69::isr0()

to

ICACHE_RAM_ATTR void RFM69::isr0()

For the new RFM69 driver (for reference):
Change the following line https://github.com/mysensors/MySensors/blob/development/hal/transport/RFM69/driver/new/RFM69_new.cpp#L245
from

LOCAL void RFM69_interruptHandler(void)

to

ICACHE_RAM_ATTR void RFM69_interruptHandler(void)

AdamAnt

@yveaux Hello, thanks so much for your help on this!

Changing those functions has helped me get past the error, however I now have a different issue.
Using the the same sketch and setup, on the old driver the gateway crashes with a Soft WDT reset shortly after it initializes the radio:

However, using the new driver, I get past that point and the gateway initializes fine. But unfortunately, the sensor node never connects. It just constantly sits waiting to find a parent node:

I'm pretty confident my antenna setups are correct - single core wire, each one a straight piece 82mm long.

mfalkvidd

@adamant are you using the new driver on the node? Gateway and nodes must use the same driver.

What does the gateway log say?

AdamAnt

@mfalkvidd Yeah, I reflashed the node & gateway each time to match.
The gateway has the same sketch as in post 1, just with #define MY_RFM69_NEW_DRIVER added, and the sensor node is the simple repeater sketch:

Hi,

i have the same problem. Using the 2.4.2 of the ESP8266 board library works fine. All later versions not.
Ther is an other Problme with the ESP Gateway. The Wifi reconnect after a soft reboot or pushing the reset switch is not working.
The gateway is trying to reconnect until it gets power on / off .

a Modification of the MyGatewayTransportEthernet.cpp helps. Wifi will be always disconnected with the boot process.

#if defined(MY_GATEWAY_ESP8266) || defined(MY_GATEWAY_ESP32)
#if defined(MY_WIFI_SSID)
// Turn off access point
WiFi.mode(WIFI_STA);
#if defined(MY_HOSTNAME)
#if defined(MY_GATEWAY_ESP8266)
WiFi.hostname(MY_HOSTNAME);
#elif defined(MY_GATEWAY_ESP32)
WiFi.setHostname(MY_HOSTNAME);
#endif
#endif
#ifdef MY_IP_ADDRESS
WiFi.config(_ethernetGatewayIP, _gatewayIp, _subnetIp);
#endif
GATEWAY_DEBUG(PSTR("GWT:TIN:Disconnect Wifi..\n")); //----------- added
WiFi.persistent(false); // --------------------------------------------------------------------added

GATEWAY_DEBUG(PSTR("GWT:TIN:Delay 500 ms...\n"));
delay(500);
(void)WiFi.begin(MY_WIFI_SSID, MY_WIFI_PASSWORD, 0, MY_WIFI_BSSID);
while (WiFi.status() != WL_CONNECTED) {
wait(500);
GATEWAY_DEBUG(PSTR("GWT:TIN:CONNECTING_wait_500ms...\n"));
}
GATEWAY_DEBUG(PSTR("GWT:TIN:IP: %s\n"), WiFi.localIP().toString().c_str());

@stefan_ne I entered two issues for the issues described above: https://github.com/mysensors/MySensors/issues/1335 and https://github.com/mysensors/MySensors/issues/1334
Please enter another issue for your case, or issue a pull request.

AdamAnt

Hello,
Just jumping in here to say that a combination of using the new driver, and downgrading to ESP8266 ver 2.5.0 has fixed this for me. The other issue I was having was total user error, a bad solder joint was giving me strange results.

Thanks for your help!!

Yveaux

@adamant thanks for reporting back!
Does this mean that https://github.com/mysensors/MySensors/issues/1335 can be closed?

Stefan_NE

Hi,

I don't think so, in time we have just some workarounds

Have a nice day
Stefan

Yveaux

@stefan_ne I would like @AdamAnt to confirm if https://github.com/mysensors/MySensors/issues/1335 is still relevant or not.
The op of this thread had 2 issues. I entered them in GitHub, then he hinted the second issue (#1335) was solved by fixing a bad solder joint.
So, unless somebody confirms #1335 is still relevant, I will close it.
#1334 is of course still to be solved.

KalleL

I had the same error and realized it was caused in combination with an interrupt routine . Having read the answers above I tried only to introduce
this directive
ICACHE_RAM_ATTR void Interrupt_routine()
{ ...code...
}

... and it was all fine :)
