    @ไฟบใŒใ‚ฌใƒณใƒ€ใƒ ใ  said in LVGL performance problem: I applied LVGL on stickc-plus2๏ผŒwith 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? Iโ€™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.

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.

    M5Tough "TOUGH TOOLS" source code?

    Felix, Thanks for the reply. About an hour or so after setting up the Arduino tools for the M5 Stack, I downloaded the M5Tough repository with a Zip file and extracted to the Arduino libraries and came across and recognized the "Factory Test" as the "M5TOUGH TOOLS" source code. Where that code was in the M5Tough-master Then when trying to compile it, I found I also had to download and drop in the code from github for M5Unified-master, M5GFX-master to get the build to complete OK. While at it, I also downloaded the M5Stack-master for other examples as well. With building the Factory Test program, I was able to go back and forth between "Hello World" and the Factory Test, so I'm a happy camper. One thing I did notice is that Factory Test program is quite extensive and for some reason, when I did a "Save as" to try and make modifications, it no longer compiled (looks like maybe some path/setup issue in looking for files). So I'll try and solve that some other time, I'm up and running now and so far, I like what I see. Thanks and best regards, Alan [image: 1664747572615-8cbe2ebc-6767-4710-9639-cfaf008c1c8c-image-resized.png]

    Hello @drobertson123 not sure it helps, but have you tried to press and hold the power key while using M5Burner? I think that should keep it from shutting down. Thanks Felix

    I have Ubuntu 22.04 and to solve it I created a symbolic link from /usr/bin/python3 to /usr/bin/python. M5 Burner tries to use the "python" command and gets an error, because the existing command is "python3". With the symbolic link this is resolved.

    Hello @Hamnet it takes time for a new board to be included in Arduino and subsequently into PlatformIO. So when M5Paper came out the easiest way to create an M5Paper PlatformIO project, was to take a similar board, in this case M5Stack Fire, which was already available. (The key here is that both M5Stack Fire and M5Paper use PSRAM.) And later on, I guess, M5Stack engineers simply forgot to fix that. Thanks Felix

    M5Stack Tough Boot Menu

    Hello @Adamk well. I think absolutely nothing isn't correct. When I set to hide the boot menu it only shows for about 1 second before starting the downloaded app whereas when I set to show the menu it shows about 4 seconds before starting the downloaded app. So yes, this option is basically useless. I would like to have an option which not only truly hides the boot menu, but also doesn't show the boot animation. At least now the startup tone can be disabled. (BTW: It is the same for M5Core2 which isn't that surprising as they probably share a lot of code.) Thanks Felix
