Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled about opendtu HOT 14 CLOSED

Hello,
the "Connection error" means that the RF module is either not connected or the connection is wrong.

You could change the line (in platformio.ini) from
monitor_filters = time, colorize, log2file, esp32_exception_decoder
to
monitor_filters = log2file, esp32_exception_decoder

and compile, upload and run the code again. Then the esp32_exception_decoder should decode the core dump and the backtrace and you should see a more detailed exception description.

from opendtu.

I changed the line, but the result in the serial monitor is still the same:

I have not connected the RF24L01+, I'm nowhere near the hoymiles either.
But my thought is that I want to be able to get into the configuration without having the RF24L01+ connected without being near my hoymiles.

A noob question, when I upload new code everything is gone, it can't be that something is left behind from a previous project that gets in the way.

from opendtu.

You can leave out the Hoymiles part by commenting out the Hoymiles.loop() in src.main.cpp line 105 and 106. I used this on a second ESP for testing.

from opendtu.

Thanks it works
Before the void loop he already went into the reboot, commenting lines 105 and 106 was not enough.
After turning off lines 80 to 98, it will continue to run.
In the configuration of the inverter there was a series of characters (no serial number of the inverter) I have removed this. Lines 80 through 98 turned on. After this, the aspen starts up.

Got an error message buffer full, but after disconnecting the RF24L01+ this message was gone, so here I have the next challenge how to connect it correctly.

from opendtu.

Buffer full is a good hint that your wiring is wrong.

from opendtu.

The buffer full message also comes without the RF24L01+ being connected, I see now

from opendtu.

This has nothing to do with my initial problem.

Can I also see somewhere when the RF24L01+ is properly connected? or only after I have added an Inverter and start reading?

from opendtu.

Can I also see somewhere when the RF24L01+ is properly connected?

Yes. You will get the following message:
Initialize Hoymiles interface... done

from opendtu.

The message is now: Initialize Hoymiles interface... Connection successfull
Tomorrow I'm going to the Hoymiles again so I can try if they are approachable.

For this I had to adjust the platformio.ini, lines 48 to 54 also placed under [env:generic]
the lines:

build_flags = ${env.build_flags}
     -DHOYMILES_PIN_MISO=15
     -DHOYMILES_PIN_MOSI=2
     -DHOYMILES_PIN_SCLK=14
     -DHOYMILES_PIN_IRQ=13
     -DHOYMILES_PIN_CE=16
     -DHOYMILES_PIN_CS=5

from opendtu.

After adding the serial number of the Hoymiles, it keeps rebooting.
After I disable lines 41 through 53 in the src.main.cpp file, it no longer reboots. Error in the config.bin?
If I delete the config.bin (how I don't know yet). Will a new one be created automatically? So I can start again at 0.

from opendtu.

I would try to erase the flash. This removes all partitions. (see https://community.platformio.org/t/how-to-erase-flash-of-esp32/27955)

After that you have to flash the esp again. but currently it seams that your littlefs partition contains junk.

from opendtu.

After a full reset, I was able to add and read both my Hoymiles without any problems.
@tbnobody where can i find the donate button? 😃

from opendtu.

Nice that it works now. I would say the issue was because of old data on in the flash memory. But not sure. Due to the fact that it's working now I am going to close this issue. Please feel free to open a new one if the error occours again.
