Re: ESP Thermal considerations

- By did not turn on I meant the 1st of option of unresponsiveness from UART(the com was recognized by the computer due to the FT231X component), - Just to make sure I 100% understand: you open a serial program at 115200bps, reset the ESP32, and see absolutely no output at all from the UART? It see...

Re: Make menuconfig generate local headers

On Windows with MINGW32 the easiest way to make builds faster is actually to move to CMake and not use MINGW32: https://docs.espressif.com/projects/esp-idf/en/latest/get-started-cmake/ To add ccache to mingw32, do "pacman -S ccache" and then set the toolchain prefix to "ccache xtensa-esp32-elf-" in ...

Re: Esp32 connected to 1-wire overheats and burns board

Hi slluch,

There still isn't enough information in your post for someone to help you. You mention a number of pin names but you haven't mentioned the model number of the GPS device you are using, so noone can help you. A good picture of your setup will help a lot.

Re: how to structure a project to build multiple binaries?

Are the utilities and test programs firmware which runs on the ESP32? If so, then suggest having multiple project directories which share a common "components" directory (the EXTRA_COMPONENT_DIRS variable can be used for this). It doesn't seem to be mentioned in the docs, but you can also have the M...

Re: skipping incompatible libraries

Does the build system print any warnings about incompatible toolchain versions (or any other warnings at all)? Can you please post the output of xtensa-esp32-elf-ld --version?

Thanks,

Angus

Re: Why ESP-IDF is always way behind ARDUINO environment

In addition to the useful links Cermak has given, there's an explanation of the different IDF branches (master, stable releases, release branches like release/v3.2) here: https://docs.espressif.com/projects/esp-idf/en/latest/versions.html We're currently in early stages of testing ESP-IDF v3.2 but w...

ESP-IDF V3.1.3 has been released

Major Bug Fixes Fixed an issue where wrong number of cache pages would be mapped if the address was less than 0x20 bytes more than a 64KB page boundary. This bug is also fixed in esptool v2.6, so images generated by the newer esptool will boot correctly even on older bootloaders. Fixed simultaneous...

Re: USB to Serial ESP bootloader issues

Error code C1 is ESP_BAD_DATA_CHECKSUM . I don't really understand the description of the test. Is the configuration with the FTDI cable sending the upload through the FTDI cable, or are you watching the upload from the CDC via the FTDI rather than via a logic analyzer? If the former, is it possible...

Re: [Answered] How to build a subset of the possible components in ESP-IDF?

Any chance -flto will ever be implemented? Yes, there's a strong chance (but no ETA that I know of). It's not like you all don't have enough on your place, but in our internal projects, we've found up to a 40% reduction in binary size when link-time optimizations are added. Impressive. Is that in E...

Re: Make menuconfig generate local headers

Hi tbitowt, We're aware of this problem (any change to menuconfig rebuilds the entire project), however there's no solution for this yet. In the new CMake-based build system, each component declares which component(s) it depends on. This means that it should now be possible to make per-component sdk...
