    You can continue developing on the M5Stack Core2 reliably. The key is to bypass UIFlow entirely and use MicroPython directly through Thonny or VS Code.

    Hello! I really love my Cardputer ADV, but I just wanted to mention something that, as a new user, didn't feel very intuitive. The original cardputer and the ADV differ to the point where firmware written for one often won't work on the other. As a new user, it was confusing that M5Burner doesn't have separate sections for the ADV and original, instead opting to have one section. Firmware creators (and even m5stack themselves), end up making two version of the firmware (one for the ADV and one for the original), and posting them in the same cardputer section. New users could miss the correct firmware version, and install the wrong one, or get frustrated when firmware that only supports the original model doesn't work on their ADV. I feel a lot of this confusion could be avoided if the m5stack menu had two different sections for the original and ADV model.

    Hi all, I’m investigating a power management issue on the M5Stack Core2 (AXP192 + external SY7088 boost) and I’m looking for confirmation or a proper solution. 🔧 System Architecture (as implemented) From schematic analysis and testing: AXP192 IPSOUT powers the system and the boost converter // VBUS ALWAYS INPUT ENABLED writeAxpReg(0x30, 0x80); SY7088 generates 5V (when EXTEN = 1) SY7088 output is directly connected to VBUS VBUS is also connected back into the AXP192 as an input ACIN is the real USB 5V input So effectively: BAT → IPSOUT → SY7088 → VBUS → AXP192 → IPSOUT ❗ Observed Problem When running on battery: -Enable 5V output (EXTEN = 1) -Disconnect USB cable -Immediately, battery current jumps to ~450 mA -System enters a self-sustained power loop 🔍 Key Observations EXTEN is correctly set (verified via register dumps, Reg 0x12 bit 6) VBUS input is permanently enabled (Reg 0x30 = 0x80) Boost converter behaves normally Loop appears only when USB is disconnected 💡 Root Cause SY7088 output is physically tied to VBUS AXP192 does not fully isolate VBUS internally The supposed N_VBUSEN mechanism does NOT break the electrical path 🔥 As a result: BAT → boost → VBUS → AXP internal path → IPSOUT → boost... This leads to: continuous energy circulation high battery drain (~400 mA) no stable operating point ❓ Question to the community Has anyone: Observed this behavior on Core2 or similar AXP192 designs? Found a way to safely use 5V boost to power external accssories from battery without loop? Thank you, Cheers, Adrian YO3HJV
