Reboot when program reaches semaphore #1004
Description
Hardware:
Board: Adafruit HUZZAH32 Feather
Core Installation/update date: ?11/jul/2017?
IDE name: Arduino IDE
Flash Frequency: 80Mhz
Upload Speed: 115200
Description:
Whenever I try to use Semaphores in my code I get the following error:
`/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/freertos/./queue.c:1441 (xQueueGenericReceive)- assert failed!
abort() was called at PC 0x40084701 on core 1
Backtrace: 0x40087360:0x3ffcd070 0x4008745f:0x3ffcd090 0x40084701:0x3ffcd0b0 0x400d0a33:0x3ffcd0f0
`
I tried it in several different cases but I never got semaphores to work on my code. The RepeatTimer example works fine though. I read that this has to do with serial connection, but for me everything works fine except when I insert a semaphore.
