Core2 resets when recoding from build in microphone

[Remco]

I recently bought the core2 because it has a build in mic, speaker and much more. Great!

But I can't get the mic to work in UIflow (online and app) or Arduino IDE. Both the most recent version.

Even the most basic Blocky makes the Core2 reset when running it.

It does create a audio file, in my case 'test.wav', but it is 0 bites. Also if i save it to the SD card.

The mic is working correctly because the factory test works fine.

I also own a M5stickC-plus (a few). In UIflow there is no mic option, but it workes fine in Adruino IDE.

So, what is going on? It seems to be a serious problem for years now, but why is nobody doing something about it?

I bought it because if the mic and speaker.

Please help me!

Yes Remco I have found the same issue with the microphone on the Core 2.
It does create an audio file to my SD card but it is 0 bites.
And yes this simple Blocky record function makes the Core 2 crash and restart.

@kombistack Damn, just stumbled into this issue also. I'm guessing there is still no fix?

Hello @m5stack team

I can confirm that trying to record (a 1 second long wav) from the microphone to SD card on an M5Core2 using UIFlow 1.11.8 fails and crashes the M5Core2 with the following error in the debug log:

[0;31mE (259807) I2S: Error malloc dma buffer␛[0m
/home/m5/M5-Workspace/esp-idf-for-m5/components/freertos/queue.c:1802 (vQueueDelete)- assert failed!

Thanks

With the Core 2's microphone, I discovered the identical problem. My SD card does receive a created audio file, but it contains 0 bites. And sure, the Core 2 crashes and restarts when using this straightforward Blocky record method.

@Remco @giftedfinance @djh82uk bug is fixed and the next firmware version 1.12.2 is supported

I just tried to record a simple .wav file via the built in microphone on my core2 with the M5Go Bottom2 using the blocky 'record to file' block. I am using UI flow 1.12.2 on my core2 and yes it does record and I can play the .wav file back but even at max volume of 6 the sound is very faint.
