Re: What's wrong when I move from breadboard to PCB?

So I think I only need to connect EN to RTS and GPIO0 to DTR and ignored them ... This is correct. With this config normal serial programs won't work without some tweaking for RTS/DTR, but esptool.py, "make monitor" in IDF, miniterm (with correct args) and some other tools will work fine....

Re: vTaskDelete

One of the FreeRTOS requirements is that tasks never return, so if you want the task to go away it needs to call vTaskDelete(NULL).

That said, there may be something we can do detect this and handle it in a way which is easier to debug.

Re: One error happen when compiling the example of ulp

All example are OK, except ULP example. My build environment is Cygwin. In your opinion,the attached (https://dl.espressif.com/dl/esp32ulp-elf-binutils-win32-7b4f341.zip) is only used for MSY2? It's not only used for MSYS2, but it's a MINGW executable which is different to Cygwin, and means it can'...

Re: One error happen when compiling the example of ulp

Hi Tony, Do you only get this error when building the ULP example, or you get an error when building other examples? What build environment are you using? ESP-IDF build system only supports using MSYS2, as described in the docs here . This example builds for me in the MSYS2 build environment we prov...

Re: Windows Environment Flash Issue Under Eclipse

The other strangeness I've seen is in this environment when building the i2c examples, I need to explicitly include #include <limits.h> #include "sdkconfig.h" or else eclipse shows errors that it cannot find some of the #defined values. (the make builds properly either way). I did not nee...

Re: make monitor error "AttributeError: 'Serial' object has no attribute 'is_open'"

Hi liuq,

Thanks for reporting this. Ubuntu 14.04 ships with pyserial 2.6, and it looks like idf_monitor uses some "new style" APIs that were only added after pyserial 3.0.

This is a bug and we'll fix it ASAP.

Re: Windows Environment Flash Issue Under Eclipse

Hi Marcus,

Sorry for the slow reply. Did you make any progress with this?

Is it possible that another version of python.exe has slipped onto the PATH somehow? Or that the PYTHONPATH environment variable is being overriden somewhere?
