@myxiplx Glad you found the issue. I have noticed that the pico header pins get worn out quick when just using headers in and out of the PCB.

Hello @Minxster I haven't looked into either of the two libraries in depth so it's difficult to say which will be more helpful for your particular M5Core2 project. @Rop was very active for a while but then moved on to non M5Stack related things I guess. That said, in the past M5Stack engineers weren't too busy adding new features (or fixing bugs) in their libraries once a particular piece of software has been out. So I don't expect too much activity in the M5GFX library except maybe small adaptions to support new M5Stack devices which have a screen. Thanks Felix

Hello @benalb according to the C Back Driver schematic the four channels are powered from the +BAT pin the M5StickC provides but is missing when using an M5Atom with the atom-mate. Thanks Felix

@felmue said in cant flash latest m5 stamp c3: Hello @HaSch well, disabling downloading the stub doesn't help anyway - so my idea is moot. I've just setup a machine with macOS Big Sur 11.5.2 and with or w/o downloading the stub the download process ends in an timeout error. What worked for me on macOS Big Sur 11.5.2 however is using the ESP32C3 built-in USB via GPIO18 and GPIO19. Thanks Felix It really seems to be an issue with USB serial driver. I also tried to download and install the CH9102_VCP_SER_MacOS driver from here without success. Trying to install to my MacOS 10.15.7 Catalina ends up with an error: 安装提示 sysex didFailWithError The operation couldn’t be completed. (OSSystemExtensionErrorDomain error 9.)

This is a great answer. It is not obvious that this functionality exists.

Hello @ajb2k3 What worked for me on macOS Big Sur 11.5.2 is using the ESP32C3 built-in USB via GPIO18 and GPIO19. What also worked for me on macOS Big Sur 11.5.2 was downloading and installing this driver CH9102_VCP_SER_MacOS from here. After a reboot and plugging in M5StampC3 via USB this port show up /dev/cu.wchusbserial... (in addition to /dev/cu.usbmodem... which did not work). Thanks Felix
