@felmue said in Looking for Factory Test Source code for Core2:

Hello @jdonth

what I meant by Arduino framework version 1.0.6 is the arduino-esp32 framework version 1.0.6 (instead of 2.0.1) and not the Arduino IDE. Sorry if I wasn't clear.

BTW: when I run the app compiled with 2.0.1 I see this error in the log:

E (2888) I2S: i2s_check_set_mclk(253): ESP32 only support to set GPIO0/GPIO1/GPIO3 as mclk signal, error GPIO number:6
E (2895) I2S: i2s_set_pin(314): mclk config failed

I was able to fix this error by adding this line in function InitI2SSpakerOrMic():

tx_pin_config.mck_io_num = GPIO_NUM_0;

Thanks
Felix

Thank you Felix! I'm glad I found your solution for this error. It finally works. I'm using version 2.0.2. I can now run the EchoSTT on my Core2.

@jdonth I'm not sure if you fixed your error. I have the same deprecated error. But it still can get compiled. My suggestion is to update the M5Stack libraries. This is what I did.

Compiling the code at https://github.com/m5stack/M5-ProductExampleCodes/tree/master/Core/M5Core2/Arduino/Core2_Factory_Test

When I run the Core2_Factory_Test I get no microphone indication (and the speaker is silent during the scrolling test phase).

I am assuming I have some misconfiguration in my Ardunio IDE but I don't know where. The following is the compiler messages from when I compile the test program (sorry for the size, I don't know what I can safely edit, except for [many] repeated warning:excess elements in array initializer):

Just to be sure this is not a problem with your unit, I would suggest you download the EasyLoader tool you can find the link on this page: https://docs.m5stack.com/en/core/core2

This tool allows you burning your Core2 with the stock demo program so that you can test it without having to compile it.

Should be a good start

No worries. I am sorry it still doesn't work for you.

How do I tell the IDE to load the 1.0.6 framework?

That I don't know. I am not an Arduino IDE user. I suggest you ask this question in an Arduino forum.

I do get those warnings in the compile log as well, they are not (yet) critical. Depricated only means that in the future this part of the code will be removed / modified and them most likely lead to an error / non working code. I guess if you'd like to get rid of these warnings you could replace I2S_COMM_FORMAT_I2S with I2S_COMM_FORMAT_STAND_I2S.

Do you have the run log? Maybe there is a clue in there.

Thanks
Felix

I tried your fix to InitI2SSpakerOrMic and it threw so many errors I knew I lost.

How do I tell the IDE to load the 1.0.6 framework?

Here is the compile log. If you can see what might be wrong?
(I edited the ...Writing lines before the 100%)

Thanks,
Joe

probably the last of the 1.0.x versions.

Thanks
Felix

my best guess would be that the code has not yet been adapted to Arduino framework 2.0.1.

Thanks
Felix
