Exception if clock is booted while website is loaded in browser #7

Closed stan23 closed 4 years ago

stan23 commented 4 years ago

If the wordclock website is open in a browser while the wordclock is powered up and booted, there's an exception.

First NO WLAN is shown, then WLAN, then the exception happens and the clock reboots.

Stack trace:

Crash seems to occur here: https://github.com/SteMaker/wortuhr/blob/master/fw/src/main.cpp#L148.

SteMaker commented 4 years ago

There is a potential fix on branch add_locks_issues_7. I couldn't reproduce any longer, but was rarely able to reproduce anyway. @stan23 Can you retest with this change?

stan23 commented 4 years ago

Just tried it, 0 crashes out of 10 reboots. Without the fix it crashed 2 of 5 times.

SteMaker commented 4 years ago

Fixed with 06bdd98a2ad62b2d2af1609e76567b8c02e3f333
