There should be something wrong on our config!
I tested here (using esp32-devkitc:psram) and it worked like a charm!
nsh> ?
help usage: help [-v] []

Yes, ESP32_PSRAM_8M is enabled.

I think that is true. Maybe Lucas can confirm if he was saving in the SDCard.

Hello,
I want to make sure that I understood this correctly, you're saying that
the I2S audio saved to an SDCard (via SPI) on Lyra T is working ok?
Also, I tried creating a ramdisk of 1mb+ for testing, but I did not find a
way do to so.
For example,
mkrd 1024 lends the error: mkrd:
Hi Simon,
Lucas just confirmed that it was working fine on Lyra T with ES8388 Audio Codec.
I think she is using SDCard over SPI (even slower).
There is not SDCard interface support for ESP32 on NuttX yet (the
SDCard uses/shares I2S interface).
The ESP32 MCU has 2 I2S interfaces, so in theory
Hi Simona,
SD Cards have busy time times of 500ms max (per spec) for saving data
internally. I saw SD Cards taking over a second of busy time.
You can check with the Oszilloskop. I think data0 is the pin that signalize
busy...
Per design, you need a stream buffer that can handle your audio

Hello,
I am trying to record audio using a MEMS microphone, but the final
recording is missing parts periodically (for example, with a sample rate of
8kHz, there are parts ~1s long missing once every ~10-11s. Using a sample
rate of 48kHz, the period is ~1s long). This is my first time working with
