You cannot hunt for the latest firmware without knowing what you’re currently running. Follow these steps:
Updating to the latest firmware is a straightforward process. Here's a step-by-step guide:
| Risk | Mitigation | |------------------------------------|----------------------------------------------------------------------------| | Power loss during write | Use stable supply + hold bootloader in RAM until write completes. | | Incompatible hardware revision | Read HW_REV register before update; abort if < 2.0. | | Bricked device after failed OTA | Keep UART bootloader pins accessible; force bootloader via BOOT0+RESET. | | Counterfeit ZXDZ 01 clones | Validate unique chip ID (UID) before update; official firmware rejects clones. |
Connect the unit to a PC via a male-to-male USB cable and use the "Scatter-loading" method. Recovering from a "boot loop" or total failure.
Resolves general interface lag and fixes persistent app crashes (such as Google Maps unexpectedly freezing during navigation).
