Build environment: Linux(22.04)
Moddable SDK version: v4.2.0
Target device: M5Stack Core2

Description

M5Stack Core2 panics on startup.
According to the instrument log, it seems to be a kind of deprecation error for i2s driver.

W (613) ADC: legacy driver is deprecated, please migrate to `esp_adc/adc_oneshot.h`
E (620) i2s(legacy): CONFLICT! The new i2s driver can't work along with the legacy i2s driver

abort() was called at PC 0x400fca4c on core 0

Steps to Reproduce

  1. cd $MODDABLE/examples/helloworld
  2. mcconfig -m -i -p esp32/m5stack_core2
  3. See error

Could you please remove build output and try again with a verbose build?

rm -rf $MODDABLE/build/bin/esp32 $MODDABLE/build/tmp/esp32
VERBOSE=1 mcconfig -d -m -p esp32/m5stack_core2 > $MODDABLE/build/tmp/debug.output 2>&1

Then send $MODDABLE/build/tmp/debug.output to me?

Thank you. Are you able to build for other targets?

I think the key thing is here: check_i2s_driver_conflict.

Here it is. I put instrumental build version (debug_instrument.output) aside just in case.
debug.zip

esp32/m5stack and esp32/m5stack_fire build and run. AudioOut can play sound.

esp32/m5stack_cores3 builds and runs but no sound plays. I will take a look if it's related to this issue.

I've delved into the implementation of audioout.c. As the error message suggests, I checked for any remaining legacy APIs for I2S. It appears that the i2s_write_expand function does not exist in esp-idf v5, which seems to be leading to a runtime error.

https://github.com/Moddable-OpenSource/moddable/blame/public/modules/pins/i2s/audioout.c#L1602

To verify this, I modified esp32/m5stack_core2/manifest.json and changed MODDEF_AUDIOOUT_I2S_BITSPERSAMPLE to 16 to bypass the use of i2s_write_expand. Doing so eliminates the relevant error, and audio playback proceeds as expected.

It looks like the M5Stack Core2 is the only public device that uses 32-bit output. That's why the use of the deprecated i2s_write_expand API was missed. The expansion has been added to the new channel API as part of initialization. Unfortunately, I don't have an M5Stack Core2 to try. Would you test the following changes in audioOut.c?

In audioOutLoop() set the 32-bit case to expand from 16-bit source to 32-bit out:

#if MODDEF_AUDIOOUT_I2S_BITSPERSAMPLE == 32
	i2s_config.slot_cfg.data_bit_width = I2S_DATA_BIT_WIDTH_16BIT;
	i2s_config.slot_cfg.ws_width = I2S_DATA_BIT_WIDTH_32BIT;

In the same function, fold together the 16 and 32 bit cases, so both use i2s_channel_write:

#elif (16 == MODDEF_AUDIOOUT_I2S_BITSPERSAMPLE) || (32 == MODDEF_AUDIOOUT_I2S_BITSPERSAMPLE)
		i2s_channel_write(out->tx_handle, (const char *)out->buffer, sizeof(out->buffer), &bytes_written, portMAX_DELAY);
#else
	#error invalid MODDEF_AUDIOOUT_I2S_BITSPERSAMPLE
#endif

It would be good to have this case working for other devices that may need it. Still, it may be just fine on M5Stack Core2 to use the 16 bit case.

Thank you!
