What does enabling hardware AES in sdkconfig do?

I have a working IoT Azure device and was looking at the sdkconfig.defaults settings. There is a good bit of MBEDTLS action happening, for certificates and keys, but the following config parameter does not seem to make a difference to whether the software works or not. Can anyone explain what is the...

Format of SPIFFS vs fopen with truncate

I have implemented a ping-pong log mechanism using two SPIFFS partitions. Each partition will have just one file. When the file on one reaches a certain size, I want to first "clean" the other partition so it has a new, empty file on it. This way, I always have (after some initial period) one full l...

Can sdkconfig.defaults be in an alternate location?

I would like to standardize sdkconfig.defaults and sdkconfig.defaults.esp32 for a particular hardware device, but have a few different applications. Is there a way to specify where idf.py should look for these files, so I don't need copies of these files for each project?
Thanks!

S2 toolchain version mismatch

I installed v4.1 latest IDF on Windows 10. The installation says it completed, but when I open the command window, it complains about version mismatch for the S2 tools. This error seems fatal and I cannot build regular ESP32 projects. All the directories seem to be where expected. If I delete the S2...

Simple questions about SPIFFS wear levelling

1. I have defined two SPIFFS partitions on main SPI flash. One is sized at 1 MByte. The other is sized at 5 MByte. When I call esp_spiffs_info() after creating them, they report sizes about ~10% smaller than their total partition size. Is this the amount used for managing the file system and trackin...

Is flash read err, 1000 normal behavior?

I have two different products and both show the following messages when I reset them using a reset button that pulls EN low. I am sure bootloader is programmed (programming step showed success on that). My application seems to run okay, but I would like to understand if this RTC WDT is normal. ets J...

Re: Coredump to flash hanging at partition erase step

I have tried again using IDF "latest" (v4.1-dev) and coredump works okay from that branch. However, now I cannot seem to get MD5 to appear in my partitions table, regardless of how I set it in menuconfig. I can use gen_esp32part.py to create one with MD5 in it. Hopefully this will be fixed soon in I...

Re: issue with toolchain, maybe environment variables

You may already know this, but v3.x of IDF used the crosstool-ng 5.2.0 toolchain. Starting with v4.x, they are using a new toolchain, the 2019r1 8.2.0. I tried using one with the other's IDF and it does not play well together. It looks like you are on a Windows host - did you install using the all-i...

Coredump to flash hanging at partition erase step

I cannot get coredump to a flash partition to work. I am using v4.0-beta1. I have 16 MByte flash WROOM device. In a simple test using the blink example, I write to a null pointer to cause crash. I found a few other reports of the same behavior: https://github.com/espressif/esp-idf/issues/3857 https:...

Re: ESP32 CMake, How to add my own static library file to project? (ESPIDF v4.1dev)

EDIT: Is BCXConfiguration.cpp the source that you want to use to make your static library? If so, I have only tried making libraries as components within a full application. So, I am not sure of the syntax for a project that is only intended to create a library. Original response: I looked at it but...
