    @俺がガンダムだ said in LVGL performance problem: I applied LVGL on stickc-plus2，with TFT_eSPI's st7789v2 driver.But the refreshing rate is very low (while doing "load screen anim").I know stickc had good performance on drawing screen (by watching the video of M5stick T-Lite Thermal tutorial). And the LVGL also has a good performance through Dial-ESP32-S3 and Din-Meter demonstration video. So what is the reason of such low performance. Cound it be the TFT_eSPI library? I’ve seen similar issues on the StickC-Plus2. It could be due to TFT_eSPI settings, try increasing the SPI frequency or enabling DMA. Also, check your LVGL buffer config; full buffering helps with performance.

    Just to share what I have done to get the debugging start working. Setup Windows 11 Adruino IDE Version 2.3.9 M5Stack StickS3 Symptom when clicking the Start Debugging button, encounter error messages as follows: Waiting for gdb server to start...[2026-06-07T13:03:42.505Z] SERVER CONSOLE DEBUG: onBackendConnect: gdb-server session connected. You can switch to "DEBUG CONSOLE" to see GDB interactions.

Diagnosis It is the driver for USB JTAG/serial debug unit (Interface 2) that causes issue. Reasons Using Zadig, found that the current driver is WINUSB (v10.0.26100.1150) The v10.0.x WinUSB driver is Microsoft's newer inbox driver that Windows sometimes auto-installs. It has been observed to be incompatible with OpenOCD's libusb on ESP32-S3 JTAG, causing exactly the LIBUSB_ERROR_NOT_FOUND error you saw. Visual Micro's own documentation explicitly warns about this: visualmicro Fix install Zadig replace/downgrade driver for USB JTAG/serial debug unit (Interface 2) to WinUSB (v6.1.7600.16385). NOTE: select "Install Driver" by clicking the dropbox on the button. The default option in the dropbox should be "Install WCID Driver" which will not help, it will still be the incompatible v10.0.x driver after Zadig installed the driver. Note on the USB JTAG/serial debug unit (Interface 0), the driver usbser (v10.0.26100.8328) is fine. There are Internet post that suggest replacing it with USB Serial (CDC). No need to make "Start Debugging" working. References IDE 2.3.0 debugging esp32s3 using built-in usb jtag Leveraging ESP32 Built-in JTAG for Advanced Debugging: A Step-by-Step Guide

    Hello @daniyyel ah, ok. So the correct documentation is here. Have a look at the code examples in Quick Start Guide to see how the M5IOE1 needs to be programmed to turn on power etc. The function is called SIM7028_EN() and first turns on power then resets the modem. Thanks Felix

    I attempted to burn the firmware for each version of UIFlow 2.0 Stick Plus on my stickC Plus, but after each firmware was burned, the device failed to boot up and did not respond to any key press.

    @platycore I came here to find a solution myself, same error running on my Linux setup. After Googling it, all the responses where "pip uninstall -y enum34", but that was not the case. I found something interesting here: https://stackoverflow.com/questions/47878060/why-is-the-re-module-trying-to-import-enum-intflag I looked at the app location M5Burner_Linux/packages/tools/enum and that was it... the app has the wrong version of enum. Remove the one with the underscores: "_ init _.py" Copy the version of enum.py located in your /usr/lib/python3.8 path That worked for me.

    Hi Rob if you look into Power.cpp you'll see that the current already is set to about 400 mA: https://github.com/m5stack/M5Stack/blob/master/src/utility/Power.cpp void POWER::begin() { uint8_t data; //Initial I2C Wire.begin(21, 22); // 450ma setVinMaxCurrent(CURRENT_400MA); are you calling M5.Power.begin() in your setup code? Or maybe the current has been reduced due the the battery being close to full? Cheers Felix

    Thanks a lot, I was almost there! I tried the UIflow firmware. The configuration button gave me an error. The burn asked me to connect to wifi. I asumed that it was the wifi of the m5, but thought that it would not work because the core was without OS. After your suggestion I unboxed the Core again (it was ready to send it back ;-) And now up and running again. Many thx ;-) Hopefully after the update the env II sensor wil work now. Because there the troubles started. Out of the box it did not work. Now i will retry.

    @funkyfab said in USB driver for Raspberry Pi: I'll answer myself ;-) I copied the /lib/udev/rules.d/69-libmtp.rules to /etc/udev/rules.d, added the line ATTR{idVendor}=="0403", ATTR{idProduct}=="6001", GOTO="libmtp_rules_end" That prevents the M5 devices to be recognized as MTP devices. Then they're recognized as Serial ports, and Arduino IDE can access them. So we don't need the driver, just a change in udev configuration. Oh cool, thats for working out how to do this. I can continue my plans of adding an RPI to my project bench to programme the M5Stacks and Sticks. Thanks you.

    Problem has been solved The weak USB cable was to blame, after replacing the cable with the original Samsung, the problem did not return. Problem messages are: "BrownOut detector was triggered" and "The Guru Meditation" something like Blue screen of Death (BSOD)

    Resource manager won't load either BMP or JPG

    @devilstower said in Resource manager won't load either BMP or JPG: I've been trying over and over to load images to my M5StickC using the resource manager of UIFlow. I've reduced the size of the image I'm loading to just 2K. And I've tried saving it as 4-bit, 8-bit, 24-bit, and 32-bit. I've tried reducing .jpg quality to an abysmal 35%. I've pretty much toggled every possible setting for saving either BMP or JPG. But each time I try to load an image, the same thing happens. Resource manager displays the name of the image, a message appears that says "uploading" and then ... nothing. The message goes away, no error is every displayed, but the image doesn't appear in either resource manager or UIFlow. Images have to be very specific and the details can be found on page 35 of my WIP book found here - https://github.com/Ajb2k3/UIFlowHandbook/blob/master/quickblockref.pdf If you have followed the guide and still get issue then you may have discovered a new bug.
