Based on the official StickCPlus code.

I usually change the /etc/ssh/sshd_config as follows:

# Authentication:
LoginGraceTime 120
#PermitRootLogin prohibit-password
PermitRootLogin yes
StrictModes yes

then you can login as the root user

Generally, No serial data received is because the ESP32 has not entered download mode successfully.

Hi @scoobysnax
Yes, StampS3 does not have a built-in fuel gauge.
I suggest you make a power supply device yourself, or you can take a look at this new M5StackTimerPWR: https://docs.m5stack.com/en/unit/Unit-TimerPWR
From the official documents and the actual photos, the battery connector of Dial is indeed 1.25mm-2P. I don't understand why the connector you bought is incompatible, or you can take a look at the official power terminal specification: https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/products/core/M5Dial/1.25WT-2P.pdf.

@teastain
Because the entire framework of UiFlow1 can no longer support the large number of new devices and new functions, UiFlow2 is equivalent to redoing all the functions.
No there is no UiFlow3

@avmg2502
You should debug line by line to see which operation caused it.

@ajb2k3
okay... after few hours of digging, I found it out that you must save the .bmp file as 16bit-depth (RGB565), mspaint does not have that feature so i got it worked by using Photoshop

The method is very simple: download the UiFlow firmware source code, copy the microPython code generated in UiFlow to main.py, change the boot option so that the device runs main.py after powering on, compile the UiFlow firmware, and you will get a .bin file running directly into main.py.

Step 1: Setting up ESP-IDF environment and download UiFlow source code

https://github.com/m5stack/uiflow-micropython
Follow the "How to build" instrument to setting up ESP-IDF environment and clone the UiFlow source code.

Step 2: Change the main.py file and modify boot option

Open up location /m5stack/fs/user/main.py and paste your code generated by UiFlow.
Open up location /m5stack/fs/user/boot.py and edit line 37-40

try:
        boot_option = nvs.get_u8("boot_option")
    except:
        boot_option = 1  # default

into

boot_option = 0 

By editing these codes, your device will directly runs main.py after booting. Don't forget to save the files.

Step 3: Build the firmware and flash into your device

Just follow the "Building the firmware" instrument, it will generate a .bin file in /m5stack/build-%YOUR_BOARD_NAME%/ and flash it into your device
Now you have your own .bin with microPython codes, you can publish it in the "User Custom" of M5Burner or other places.

If there is any better or easier way, please discuss it with me.

@ajb2k3 @Remco
this is a known issue, fixing

@vxgvxg
Yes, these Bases will be adapted to UiFlow2, give it some time

@echiz
导入外部C的库到microPython里，这个具体怎么实现的我也不清楚

@thinpoint
have you install the device driver

@echiz 对

@echiz
M5.Lcd是M5GFX实例化的一个对象，在m5stack/components/M5Unified/M5GFX

@avmg2502
You should debug line by line to see which operation caused it.

@JNVoirol

Just switch the esp32 library version in the boards manager to below 3.1.0.

お役に立てて嬉しいです。

According to the schematic diagram, the 5V of the Pogo pin is directly connected to the VIN pin. So I think maybe you can determine whether the Pogo pin is connected by judging whether the battery is connected

@UIgAVvwEs
You can try to manually allocate a larger buffer to verify whether the PSRAM is loaded correctly:
