M5StickC Plus 2 speaker is crashing program

[vectorcrumb]

Hello, I'm trying to use the Speaker on a M5StickC PLUS2. I'm using Platform.IO with the esp and arduino frameworks. The relevant setup code here is:

auto m5_cfg = M5.config();
m5_cfg.external_rtc = true;
m5_cfg.internal_spk = true;
M5.begin(m5_cfg);
M5.Speaker.setVolume(200);

I then call the speaker with:

M5.Speaker.tone(2000, 1000, 0, true);

This causes a crash. I've attached the relevant parts of the coredump below

For some reason, the speaker task is crashing due to an overflow in the stack size of the task. Any ideas what could be going wrong in my config or might this be a bug?

Hello @vectorcrumb

your example code runs fine for me - no crash.

Are you using the latest versions of M5Unified, M5GFX and M5StickCPlus2 libraries?

Thanks

Hello, @vectorcrumb
Sorry for the late reply.

I am unable to reproduce the crash.
Please try the latest develop branch.
