ESP32 crashes after 84-th UART read #224

Closed xPaRi closed 5 years ago

xPaRi commented 5 years ago

Hi, after 84 uart.read(...) from non active port is ESP32 restarting.

In real operation, there are also valid read operations, but when the total number of 84 is reached, a restart occurs.

TRY-CATCH did not help.

Example: index = 0 uart.attach(uart.UART1, 9600, 8, uart.PARNONE, uart.STOP1) print("START") while(true) do s = uart.read(uart.UART1, "*el", 100)

index = index + 1 print(index) end

Rebooting...

probably same as https://github.com/whitecatboard/Lua-RTOS-ESP32/issues/204

fixed in 9e61e52725c4b77574e9bf9261a96f918ab779f5 as it currently only is in my fork and the PR #184 you may want to cherry-pick it.
