I -Generate a Flash Encryption Key -Burn it to efuse -didn't burn any efuses manually (no encrypt_cnt , cnf ..etc ) -Now I open menuconfig , enable flash e...

Thank you so much You're a life saver my friend .. thank you . I have one more question .. what is the proper workflow for this ? right now .. I have a cmake script that writes to the flash during the Build process ! , to escape the encrypt-flash process and flash as a plain text , so .. Ignoring th...

I looked again at this subject , and I figured out what should be done create the Key partition and NVS partition , find them in the software and then access them . but in the Test Case (the link above) , the keys are in a bin format that gets combined with the firmware itself and then read and writ...

As far as I understand the documentation , THE NVS partition (the main one) is not encrypted , So I initialize it with nvs_flash_init(); // only for the main NVS even if Flash encryption is enabled Now my other NVS partition is ...

If I execute idf.py flash monitor All is done and the partition is built and flashed but the problem is if I execute idf.py menuconfig the ...

Thanks for pointing that out I'm not sure how to work with offsets in that case My partition table has no offsets (only partition sizes) in anticipation for the bootloader expansion after enabling secure boot and flash encryption. I'm looking for a similar way like spiffs because it will save me the...

Thank you for the suggestion , But this will require the 2 stage flashing as well

Hello I always used SPIFFS , they are great for storage .. they have a way to upload while building and they are super easy to work with . The only down side now is it can't be encrypted , So I look for NVS .. I found lots of posts here about sector size and each file shouldn't exceed 2KB ?? Some Ce...
