M5STICK OLED cant turn on
-
I erased the firmware a couple of times and managed to have it working with firmware version 1.2.3. Other versions did not work. Am I doing sth wrong or m5strick oled is only working with version 1.2.3
I am using windows 10 and uiflow. -
I'm not sure whats wrong there as I have 1.4.1 StickC running on both of mine.

- Turn M5StickC off
- Remove USB C from M5StickC. (If plugged.)
- Connect BAT and GND pins together with a jumper wire (male to male).
- Plug USB C into M5StickC and finally ...
- Remove immediately jumper wire.
Your M5StickC will now work as expected !
Do this every time M5StickC battery is drained because of bad HW design. :-(

It can be started by the following method.

Just to confirm. I am using M5stick OLED, not M5stickC. Does latest firmware also work with M5stick OLED?
-
@hetzer arg no it doesn't :(

Unfortunately M5Stack decided to drop support for the original M5Stick after version 1.2.3 without telling anyone. Firmware version 1.2.3 and below use a different fork of micropython, namely loboris's fork https://github.com/loboris/MicroPython_ESP32_psRAM_LoBo

ah so it was 1.2.3 they dropped support. Now this gives me some point of reference as I had forgotten which version it was.

Version 1.4.2 and version 1.4.3 works as well.
One mistake I made and probably some others made is that you have to select the StickC version in MBurner. Also, only the 115200 speed was working properly. With the other speeds, I had "A fatal error occurred: Timed out waiting for packet header". Once the new firmware is flashed, disconnect the cable and reset the board by connecting the Gnd and the Bat connectors with a wire jumper.
