Hi fasani,

You may find some of the tips here useful:

(Note that a few of these options are only available on master branch ESP-IDF, but many are available in older versions also.)

Sorry, I meant to write "export.sh". I'll edit my post for future readers. The other thing is that CMake saves the current toolchain path inside the build directory, so it's necessary to run "idf.py fullclean" or delete the build directory after changing toolchain versions in a single project. We're...

Could you, please, enable LTO (link time optimization) support? I see in https://esp32.com/viewtopic.php?f=13&t=361&start=20 that you decided not to implement LTO because you did not see significant code size reduction. Hi jhnlmn, We would really like to have LTO enabled as well. I think you may ha...

If the trend is to migrate to the latest 2021r1 gcc, I hope this migration for other branches will be done ASAP. It's really very inconvenience that switching branches needs to re-install different version of toolchain. We will update the 2021r1 toolchain on the release/v4.3 branch but not on the o...

That's right, changes in the IDF directory will cause git to flag it as "dirty".

And v4.3 is the latest stable version, you can always confirm this by checking https://docs.espressif.com/projects/esp-idf/en/stable/ (the exact version is in the top-left)

Try removing the extern "C" guards totally and include the C++ versions of these headers: #include <cstdio> #include <cstring> #include <cstdlib> EDIT: I'm not able to reproduce this with just the snippet of code you posted. Can you give a source file that's enough to reproduce the error, and also t...

Hi brazoaeye, Sorry for the inconvenience of having your components no longer build. This was a deliberate design decision in order to optimize the build process, especially the linking part of the build, and encourage hierarchical component design. You can read about component requirements in the d...

I'm afraid not, support was only added in ESP-IDF V4.1 so you will need V4.1 or newer. If updating ESP-IDF then suggest moving to the latest stable release version, V4.3.

Hi AlberK, Verifying RSA saves significant time during the boot process, especially because of the RSA accelerator hardware. Secure Boot V1 ECDSA signification verification adds a noticeable pause to the boot time (order of hundreds of milliseconds). RSA signature verification during boot is over te...

I am suspecting some of you may be bored or upset seeing my another post about USB.

Definitely not bored to see your continued adventures with USB!
