0.9.1.b1 is crashing in 15 seconds
-
It was working after the upgrade for few hours and crashed. Now after a power off/on cycle or pressing the reset button it works (I mean LED blinking) for 10-15 seconds and stops working. LED is dark, WiFi AP is not visible, can't connect to it.
There were no any program used, only original boot files and few os/gc commands to check memory and fw version.
Previous version was running for days without crash.
What can I do now? Is it possible to downgrade it to the previous release?
-
After disconnecting power for few hours now it works again.
-
Now it happenes again as reported in the opening post. It is crashing shortly after reset or power off/on cycle. No hartbeat LED, no WiFi, board is not available.
Any advice?

Hello bmarkus,
Do you have any scripts running on the board?
I think your problem could be related to this:
https://forum.pycom.io/topic/88/how-to-solve-the-firmware-update-failures
Would you be able to run that tool and let us know if that fixes your LoPy?
Anyway, we are preparing a new tool that will completely reflash the LoPy (bootloader included), once Espressif fixes the bug in the IDF that is messing with the external flash status register and causing these weird failures.
Cheers,

DanielNo, nothing is running, system is clean as it was shipped, only fw update applied.
I'm busy now, will wait for the friday update.
