It seems deleting the sdkconfig file and setting up the configuration options from scratch seemed to fix the issue. I did not take the time to figure out which setting caused the issue I was having.

I keep getting a TG0WDT_SYS_RESET reboot although, all the tasks seem to be working okay. There is not much context given for the issue. I get the following output. I'm running the latest code from GitHub and have the latest xtensa gcc compiler. Any ideas on how to debug this issue? ets Jun 8 2016 0...

Thanks. Is there anyway to force a flush of the hardware fifo buffer such that it can be read by uart_read_bytes()?

Hi, I have some time critical code where I need to read data from the UART, wait for a specific character (using UART_PATTERN_DET), read the buffer up until the detected character and then, if conditions are met, write a new set of characters to UART TX (within 4 milliseconds). The only issue is tha...

Thanks, in the end it was actually a bug in my own code. I should have commented on this earlier.

When using `uxTaskGetStackHighWaterMark(NULL)` within a task, it always returns zero. Even with a very large stack.

Any ideas?

@kolban, that worked thanks. The funny thing is that I have read your previous post on this and tried that solution, but I received other error messages. So I gave up on that route. In a nutshell I changed the CONFIG_MEM_HEAP_AREA_SIZE value to (100 * 1024), probably way too much, but for now it's o...

I am getting the following error when compiling on the ESP32: /opt/Espressif/xtensa-esp32-elf/bin/../lib/gcc/xtensa-esp32-elf/5.2.0/../../../../xtensa-esp32-elf/bin/ld: /home/simon/Projects/esp32/build/nibbl.elf section `.dram0.bss' will not fit in region `dram0_0_seg' /opt/Espressif/xtensa-esp32-el...

Thanks Neil, that is very informative. I have experienced similar issues with Espruino.

@jumjum23 Thanks for the reply. First we have some low level performance critical UART stuff to do, so we need to write custom firmware. On the "heavy" JavaScript side it's downloading and parsing 1 to 2 kB of JSON over MQTT using TLS, also posting other JSON objects over MQTT too. Also running vari...
