Namaste Forum Member,
I've downloaded the FreeRTOS Device Software from the below Amazon AWS link after logging into my AWS account.
https://console.aws.amazon.com/iot/home ... e/freertos
Details of the downloaded FreeRTOS Device Software are as below:
1. Configuration: ConnecttoAWSIoT-ESP32-DevKitC
2. Hardware platform: ESP32-DevKitC
3. FreeRTOS Version: 202002.00
I could compile and build the aws_demos project and generate the aws_demos.bin file. The output of the ninja command is shared below.

========== Log ends ==========
The aws_demos project is a project created for demonstration of all the AWS features supported; libraries of the like BLE Management, MQTT, OTA Updates, etc.
Question 1:
For creating a new project, do I need to create another project folder (Example: "myProject01") in the same folder where the "aws_demos" folder resides i.e., the "..\FreeRTOS\vendors\espressif\boards\esp32" folder path? In this case, there would be a lot many CMakeLists.txt files (inside multiple folders of the parent "FreeRTOS" folder), inside which I need to make "file-path" changes to point to the "myProject01" folder instead of the "aws_demos" folder. Is this correct or is there any better way for compiling and building a new project?
Question 2:
How do I get project specific compilation and build, considering multiple projects inside the "..\FreeRTOS\vendors\espressif\boards\esp32" folder. For example, there could be multiple projects inside the below esp32 folder, as below.
a) ..\FreeRTOS\vendors\espressif\boards\esp32\aws_demos - Existing demo project
b) ..\FreeRTOS\vendors\espressif\boards\esp32\myProject01 - My first application project
c) ..\FreeRTOS\vendors\espressif\boards\esp32\myProject02 - My second application project
d) ..\FreeRTOS\vendors\espressif\boards\esp32\myProject03 - My third application project
For example, I might need to compile "myProject01" and "myProject02" projects separately or, only one of them.
Question 3:
Does the current Amazon FreeRTOS and ESP32 framework/ architecture mandate to create new projects inside the below path?
"..\FreeRTOS\vendors\espressif\boards\esp32\"

Re: Amazon FreeRTOS and ESP32 - Few questions on new project creation
I did few projects with AFR, but i never been trying to compile few projects inside the same AWSFreeRTOS folder. Looking at folders structure it should be possible to keep projects as siblings aws_demos:dipen@1337lab.io wrote: Question 1:

This way you should be able to keep sdkconfig, partitions.csv separate for each project.
Those projects should be considered as separate projects and compiled only one at time.dipen@1337lab.io wrote: Question 2:

Yes and no.dipen@1337lab.io wrote: Question 3:

Yes, because it is how AFR is structured. No, thanks to esp-idf structure. In esp-idf you can use components, and in this case we can consider AFR as component. Here you can find all or almost all you need to start with AFR as esp-idf component:
https://github.com/aws/amazon-freertos/issues/832
https://github.com/aws/amazon-freertos/issues/1652
and personally i like to start with cloning this repository:

Namaste chegewara,
Sorry for this delayed reply.
Thank you very much for your inputs on my queries and, the additional useful links provided.
I'm happy to share that I have been able to create and build a simple Blink LED project using Amazon FreeRTOS on the ESP32 DevKitC board. Feels nice to see the LED blinking.
In the world of Embedded Systems, the Blink LED project is the Hello World !! equivalent of pure software projects.
Thanks | Regards,
