You can enable flash encryption and NVS encryption, then use NVS to store WiFi credentials. NVS encryption works with a separate encryption key that is encrypted using flash encryption. I.e., you don't need to store any key outside the device. Once you enable flash encryption, any partition marked a...

Hi, I'm the author of https://github.com/espressif/esp-idf/commit/aca9ec28b3d091a73605ee89ab63f8f76a996491. Back in the day when I was working on NVS, we also thought about allowing NVS to use the generic flash encryption scheme. In the end, however, we figured that it would have required a bunch of...

One more question: which IDF version - specifically, which commit - are you using?

Hi!

To debug these type of linker issues, it would be easiest for us if you can provide a minimal reproducing example. Would that be possible?

If you want to have low-level access to the flash, it's probably best to use the ESP-Partition (https://docs.espressif.com/projects/esp ... ition.html) API. But then you really need to take care of proper wear leveling yourself.

For testing and example applications, you could simply add a project inside your component. This is done for many IDF components which have a "test_apps" directory containing test apps. Similarly, you can add examples like this. You need to make sure to correctly use the enclosing component then, e....

Hello, we're sorry you had a tough time with the IDF build system. It shouldn't be difficult for users to use it. I have a few questions, maybe just to better understand the issue here: IDF projects usually build one executable. An IDF project basically bundles configurations, sources and other thin...

Hi, I found this guide which focuses on WiFi testing, but also mentions some of the flashing tools: https://www.espressif.com/sites/default/files/documentation/production_testing_guide_en.pdf Regarding the "device key", there is some information how to write it into NVS here: https://docs.espressif....

If you really don't want allocations to happen in a certain area, have you tried "reserving" it by doing the allocation before the other (smaller) allocations? If you need that space temporarily, you can still try to assign memory from the "reserved" space temporarily, effectively implementing your ...

Hello, what might be the issue here is a C++ object declared static which is doing some initialization in its constructor before the necessary components are initialized. Is there something like this in the code? Do you have a complete reproducing example? This would help us a lot with debugging. Ki...
