Re: ESP32S2 Digital Signature Peripheral vs. HSM

Hi Patrick, You're correct that the Digital Signature Peripheral is intended to fill a similar role to an on-board and off-chip HSM. In both cases, the idea is to have some secret key material that cannot easily be copied by an attacker even if they obtain full access to the hardware and software. T...

Re: Error build simple project eclipse hello_world for the esp-wroom-32, failed installation package cryptography

Hi lucia, Which ESP-IDF version are you using? MSYS2 project removed Python 2 packages (as Python 2 are now end of life) so we had to rebuild the MSYS2 Windows environments to use Python 3. If you're using ESP-IDF v3.3: We haven't released ESP-IDF v3.3.3 with this fix yet, but it should be possible ...

Re: ESP32S2 running ULP-FSM example sought

Hi Bernd, I'm afraid that, as you've noticed, we haven't updated the ESP-IDF ULP-FSM examples to work on ESP32-S2 yet. However the two ULPs are very similar, it should be possible to start with an ESP32 ULP-FSM program and make a few tweaks until it works. Sorry I don't have anything more specific I...

Re: help error undefined reference to `_Unwind_GetTextRelBase

Hi mohasrj, Which ESP-IDF version are you using? If you have C++ exceptions disabled in the project config (disabled is the default), then this looks the same as these two issues: https://github.com/espressif/esp-idf/issues/5363 & https://github.com/espressif/esp-idf/issues/5224 There is a pull requ...

Re: When does ESP-IDF v4.1 is expected to be released?

Hi Gal, There are still some bug fixes outstanding, but we're planning to publish a release candidate (-rc) in mid-July. Usually the final release comes a week after the release candidate. The changes between now and the release should be minimal, so if you're starting a new project then I suggest u...

Re: ESP Flash Download Tool, Combine Functionality

Hi Alex, There are two bytes in the header of the bootloader ( see here ) that determine the initial flash configuration mode of the bootloader (SPI flash speed, mode, size). Both the GUI flash tool and esptool.py can change these arguments at flashing time. This is why the value may be different wh...

Re: CMake - Nested component

So had to revisit this. The stuff in the ADF doesn't allude to much, perhaps I am not seeing it? If I use: set(EXTRA_COMPONENT_DIRS foo) Does that overwrite what I previously set in the root of my project, or does it append to it? If you put this line in the component CMakeLists.txt then it will pr...

Re: Certain header files can only be imported from main.c

Hi letsbuild, The CMake build system tracks dependencies between components, so components need to declare the other dependencies that they require. "main" component is the one exception to this rule, it automatically requires all the other components. A full explanation can be found here: https://d...

Re: CMake building problems adding the cpp_utils component by N.Kolban

so I added "bt" to the default CMakeLists.txt that was in the NKolban Repo.... Is this the only place that it is needed, or are you suggesting I need to add a requirement for including headers? Doing this will allow this component's source files and headers to include headers defined in the "bt" co...

Re: Flash is too slow

it takes a good amount of time building all the components in the ESP-IDF, inside the "build" directory inside the project. This also occupies hundres of MBs with redundant files. What am I doing wrong? I am on Linux. You're not doing anything wrong. Unlike in Arduino, the project configuration men...
