    • RE: Unstable Program uploading to M5Stack Fire

      Hello macsbug,

      thanks you for the detailed information, so the component should be missing on fire devices.

      Back to my problem I have additional information.

      I can confirm that the uploading is always working over internet. It only struggles over USB.

      Is there anything else I can check?

      PS: I have tried it on different USB ports and event machines (Mac and PC).

    • Unstable Program uploading to M5Stack Fire

      Hello M5Stack,

      I have bought now two M5Stack Fire modules from two suppliers and have issues programing them in a stable manner wit UI Flow.

      One of tham has a chance of ~10% to get programed, the other ~50%.

      I have read the common post related to that issue and the recomendations to put a capacitor on the EN / RESET Line.

      For me the issue is quite clear because every time I cannot program the board I see that the board got a reset. I have taken a osciliscope picture of the signal from the MBUS Plug and can see a pulse on the RESET line on each program attempt. If the pulse gets too low I have a reset and the programming fails.

      I had also a closer look at the PCB and recognized a "missing" component near the RESET button:

      Is this a hardware issue? Why two of the boards from different sources have the same issue.

      I hope you can clearify the issue. The baord seems to be a perfect fit for learning purposes.

      Best Regards

      Rafael.
