  お世話になります。

  現在、M5Stack FIRE に関して次の2つのバージョンがあります。
  　　1) V2.6 (USBチップ: CH9102F) ※BALA2 FIREとして購入したもの
  　　2) V2.7 (USBチップ: CH9102F)
  2)のV2.7については、Windows11(24H2)で問題なくUSBシリアルポート接続
  認識ができていますが、同一環境(PC環境、USB接続環境、USBケーブル等)
  で、1)のV2.6について、デバイスマネージャでCOMポートとして認識できず
  困っています。

  様々なUSB環境(ハブ、ケーブル等)で試していますが、一瞬接続できたことも
  過去にありましたが、現状は、ことごとく正しく認識されません。

  もし、同様のトラブルに遭遇された方で、アドバイスなどがございましたら
  よろしくお願いします。

  Burn of UIFlow2 (v2.2.4-16MB) to M5Core-Grey using M5Burner loads stub but not full firmware. Burn of UIFlow_M5GO (same M5Burner) works fine. The UIFlow2 burn results in inoperable M5GO even though final message says 'Burn Successfully, click here to return'.

  Here is screen shot of output from Burn:

  --chip auto --port /dev/tty.usbserial-01DB92E6 --baud 1500000 --before default_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x9000 /Applications/M5Burner.app/Contents/Resources/packages/tmp/uiflow2-cfg.bin

  Please follow this instruction and see if helps:

  Observe whether there are any obvious physical damage marks on the device. Install the device driver: Windows: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/drivers/CH9102_VCP_SER_Windows.exe macOS: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/drivers/CH9102_VCP_MacOS_v1.7.zip Connect the device using a USB cable and open the device manager. Check whether the device manager page refreshes when the device is inserted, and whether a new device appears in Universal Serial Bus controllers. If not: If you are using USB C to C cable: First disconnect the StickCPlus, turn off the device, and then plug in the cable (press and hold the power button until the green light turns on to indicate that it is turned off). Or replace it with an A to C cable. If you are using USB A to C cable: "Try to change the data cable", "Try to reinstall the driver", "Try to change the PC". Reburn the factory firmware: https://docs.m5stack.com/en/guide/restore_factory/m5stickc_plus. The screen is still black after burning: Press and hold the leftmost button until the green light inside turns on, then plug in the USB cable Observe whether the screen is black but has a faint backlight, and whether there is a beep sound when pressing the button

  I just got the M5GO Kit, and I'm trying to make a Voice Assistant. For some reasons, the Demo of the kit made me think that accessing the microphone is easy. But, after hours of finding, it seems that there is no library or support for the kit to record audio. Does anyone have any resource regarding this?

  Problem:

  Der Schrittmotor funktioniert nur korrekt in der Z-Achse bei normalen (langsamen) Drehgeschwindigkeiten.
  Beim Versuch, die X- und Y-Achsen zu verwenden, funktioniert der Motor nur, wenn ich die Vorschubgeschwindigkeiten auf das 10-fache oder höher erhöhe.
  Wenn ich versuche, die Adresse auf 0x71 zu ändern, wird das Modul nicht erkannt.

  I got to necro this thread, since I want to transfer JPEG from UnitV (2640) to Fire Core.

  @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.
