It looks like PlatformIO is still uploading your filesystem as SPIFFS despite setting board_build.filesystem = littlefs. This happens because the default partition table might not reserve space for LittleFS. Try creating a custom partition table that supports LittleFS and specify it in platformio.ini with board_build.partitions. Also, ensure your LittleFS_esp32 library is compatible with M5Core2. Without proper partitioning, mounting fails with corrupted directory errors like yours. Let me know if you want help generating a suitable partition CSV file!

Hello @hacxx

please refrain from posting in year old threads which are already resolved. Thank you.

Thanks

@Boomvalt Xcode is OSX's dev environment and is needed for some low level functions needed for hardware programming even if you are not directly using it.

@kuriko
Thank you for your hint. However, I don't know how it could help to solve my requirements.
In M5StickC-Plus example, IMU will remain powered on and will send interrupt on gpio 35 on motion.
In my requirement, axp2101 could send interrupt on power-on (usb), but its interrupt pin is not connected to esp32.
AXP2101 usually wakes up esp32 by simply powering on esp32, it is not a real wake up by interrupt. Therefore, wake up by power-on (usb) works only if esp32 was powered off by axp2101 previously. I cannot power-off esp32 because it should also wake up on gpio interrupt from PIR.

@ajb2k3 I haven't, but just did!

for Hive MQTT below works for me Uiflow 2.2.5

Hello @Krmiller

GetVBusVoltage() exists in M5Core2 library as well. See here.

@pleister found the solution in rebuilding the extension https://github.com/curdeveryday/vscode-m5stack-mpy/issues/45

Hi all,

I have been looking for the answer to my problem and my best guest might be the fact that they both are using PortA, thus the competition.

Is there a way to switch from one sensor to another to get a reading from both?

Thank you in advance :)

@paulasousa it may be a cause of code changes in the libraries. You need to check the documents for the update records.
Probably better to rebuild from scratch

@perlix
Hi, are you sure to remove the line 'Serial.begin(115200);' in setup() and not change it to 'Serial.begin(9600);' or something else? I remove this line and compile it , a lot of error occured. Any advise. Thank you.

What about M5CoreS3? Doesn't seem to have BL pin defined. Can it be used with TFT_eSPI?

@JourneymanWizard No, I'm saying that not all cables are power+data. some cables are data only.
Also for some reason I have noticed that cables of late have a high failure rate (conductors breaking.
You are a core3, Have you pressed the boot button?
Another thing I have also noticed that I have to use a USB hub between the device and the computer for some reason.

I had this. Take it apart, disconnect battery, wait a minute or two, plug it back in. Something in the pmic is buggy and this resets it then it works.

@IndianaTux
this works on my CoreS3, directly turns off LDO2

#include <M5CoreS3.h> #include <Wire.h> void setup() { // put your setup code here, to run once: Wire1.beginTransmission(0x34); Wire1.write(0x12); Wire1.write(0b01001011); // LDO2, aka OLED_VDD, off Wire1.endTransmission(); }

@raeph
maybe these codes will help:
