Firmware with a .uf2 file causes T-echo to freeze completely. It is not in the device manager, so I cannot flash it using Platform IO.
The T-Echo can only be flashed through it’s bootloader (the TECHOBOOT partition) or using an SWD debugger (which requires special hardware and opening the T-Echo case). There is no code in my firmware that can trigger the bootloader via USB, so you have to double-click the reset button to make it do anything over USB and show up as TECHOBOOT.
If my firmware just does not boot after flashing, this may have a number of reasons:
t-echo-lora-aprs-with-sd-v0.8.uf2
(note the -with-sd
part in the filename!).
T-echo stopped showing up in device manager. Shown only as TECHOBOOT partition when double-clicking the upper side button. How to return to the previous state to flash for example Meshtastic?
