Support for ESP-IDF style ESP8266_RTOS_SDK

[srini1948]

The current ESP8266 on PlatformIO is very old. Could you please consider adding the new ESP-IDF style ESP8266_RTOS_SDK. The SDK structure is similar to that of ESP32-IDF.

[ivankravets]

@WallaceWilliam could you help us with PR? I see you are working on https://github.com/WallaceWilliam/framework-esp8266-rtos-sdk-idf-platformio

No need to rename framework to framework-esp8266-rtos-sdk-idf. We will use it instead of old implementation.

[WallaceWilliam]

this is my hobby. I am ready to do everything in my capabilities.

[srini1948]

Yes – it will be better to replace the old ESP8266_RTOS_SDK rather than have this custom version. Thanks.

version ESP8266_RTOS_SDK in https://github.com/platformio/platform-espressif8266 is 1.5.0-beta
version ESP8266_RTOS_SDK in https://github.com/WallaceWilliam/framework-esp8266-rtos-sdk-idf-platformio is current branch (v3.2.dev-...) of https://github.com/espressif/ESP8266_RTOS_SDK
These versions are not compatible. and all projects written on the old version (1.5.0) will not work.
I have projects in both versions.
for you I can make a separate branch where the framework version 3.2.0 will be framework-esp8266-rtos-sdk. not framework-esp8266-rtos-sdk-idf

[srini1948]

I am still having problems with the “custom8266” version – it already has the “option” true setting in platform.json. Once I install this custom platform the new project Wizard of PlatformIO in Visual Studio Code shows Arduino as the only option for ESP8266 boards! It seems to remove the three other options: Simba, RTOS and NORTOS It does not show the newly installed Custom platform at all. I guess a fake Arduino project has to be created and its Platform.ini has to be manually edited. I don’t need the 1.5 version. It will be great if as you suggest framework-esp8266-rtos-sdk will itself be replaced by the 3.2.0 Thanks.

@WallaceWilliam

These versions are not compatible. and all projects written on the old version (1.5.0) will not work.

You can control the framework version using platform = espressif8266@x.y.z.

[WallaceWilliam]

I rename framework from esp8266-rtos-sdk-idf to esp8266-rtos-sdk
please test

I tried (because I really really want to develop something with FreeRTOS) to install per above notes with no success.
I used the Master github from @WallaceWilliam , extracted into Platforms/custom8266, ran
pio platforms install custom8266
and then
pio run
. Platform.ini has platform = custom8266 and framework = esp8266-rtos-sdk. The result is: (there were no other errors)

Ok, that did it!!!!
I uninstalled custom8266, copied new .zip file from your repository, unzipped it in 'packages'.
Then 'pio platform install custom8266' and 'pio run -e 8266' (I have several [env] in my .ini file).

Result is an upload attempt to my device, that failed unfortunately due to having space in file path :-(

@WallaceWilliam any clue why PlatformIO on VS Code won't find the tools from the toolchain when trying to "build" code?

[WallaceWilliam]

please, post platforms\custom8266\platform.json

[DrywFiltiarn]

The problem lies in the fact that your implementation so far is only aimed at Windows. As I’m on a Mac it could obviously not install the required tools. I have been working on 2 forks of your repositories to also support the osx toolchain. I will come back on this later.

[WallaceWilliam]

@DrywFiltiarn I redisign platform.json and add support for OSX
But I can't test it because I don't have OSX
And in xtensa-lx106-elf\manifest.json set "system": ["linux_x86_64"] But it's not right. you must determine the type of systems for OSX
otherwise the toolchain for OSX will not be installed

[DrywFiltiarn]

@WallaceWilliam the systems for OSX will be: "darwin_x86_64" or "darwin_i386" both use the same toolchain download.

What you configured now for the manifast is invalid.
{ "system": ["linux_x86_64"], "url": "https://github.com/WallaceWilliam/xtensa-lx106-elf/raw/master/xtensa-lx106-elf-osx-1.22.0-92-g8facf4c-5.2.0.tar.gz", "version": "5.2.0" }

needs to be
{ "system": ["darwin_x64_86", "darwin_i386"], "url": "https://github.com/WallaceWilliam/xtensa-lx106-elf/raw/master/xtensa-lx106-elf-osx-1.22.0-92-g8facf4c-5.2.0.tar.gz", "version": "5.2.0" }

You could add Linux as well, but that would require you to copy the correct tar.gz from espressif and modifity it to contain the correct package.json.

The manifest in my fork https://github.com/DrywFiltiarn/xtensa-lx106-elf-1.22.0-92-g8facf4c-5.2.0/blob/master/manifest.json is configured correctly for osx.

Hi
add in the sdkconfig.h
#define CONFIG_USING_SPIFFS 1

[boriss2oo6]

Thanks @WallaceWilliam !

My first solution was to delete spiffs folder from sdk components(because i don't need this feature in my porject).
The solution provided by you is great but still the project gives me a few compiling errors which i solved by adding to sdkconfig.h:

#define CONFIG_USING_SPIFFS 1
#define CONFIG_SPIFFS_META_LENGTH 4
#define CONFIG_SPIFFS_GC_MAX_RUNS 10
#define CONFIG_SPIFFS_MAX_PARTITIONS 3
#define CONFIG_SPIFFS_OBJ_NAME_LEN 32
#define CONFIG_SPIFFS_PAGE_SIZE 256

Hi all!
Several days ago Espressif has deprecated NonOS SDK.

Support Policy for ESP8266 NonOS
Starting from December 2019,

We will not add any new features to the ESP8266 NonOS SDK.
We will only fix critical bugs in the ESP8266 NonOS SDK.
We will only maintain the master branch of ESP8266 NonOS SDK, which is a continuously bug-fix version based on v3.0. This means:
All other released branches will not be updated.
All the future versions will be released from only the master branch mentioned above.
It is suggested that the ESP8266_RTOS_SDK, instead of ESP8266 NonOS SDK, be used for your projects.
The latest ESP8266_RTOS_SDK allows users to develop applications using an architecture that are compatible with the SDKs of all Espressif chips, including ESP8266 series, ESP32 series, and the upcoming new series of chips. Switching to ESP8266_RTOS_SDK will helps users to:

Eliminate the necessity to maintain more than one applications (for different chips), thus greatly reducing maintenance costs.
Easily switch to other Espressif chips in the future for enhanced flexibility, less dependency, and reduced time-to-market.
Thank you for your interest in Espressif products.

What about updating RTOS in platformio to the up to date version (release/v3.3)?

Can you concentrate your forces in support of a single framework, please?

I'm trying to write wemos d1 mini pro firmware for a couple of days with different approaches.
The only +/- correctly working is VS Code + PIO (a tried also CLion with esp8266 plugin and other CLI approaches that are too hardcore for me (I'm on Windows)).

Thanks.

I installed the platform using the command
pio platform install https://github.com/WallaceWilliam/framework-esp8266-rtos-sdk-idf-platformio.git
Which installed

custom8266 @ 0fff40c has been successfully installed!
PackageManager: Installing toolchain-xtensa-lx106-elf @ 5.2.0+100

I created a new project, selecting a board from the custom8266 section, and went to compile.

- toolchain-xtensa-lx106-elf 5.2.0+100
 File "C:\PlatformIO\.platformio\platforms\custom8266\builder\frameworks\esp8266-rtos-sdk.py", line 242
   line = line.replace('"','')
                             ^
TabError: inconsistent use of tabs and spaces in indentation

EDIT: I fixed this by copying the indentation of the line below it to this line with the error.

Then I received this;

PACKAGES:
- framework-esp8266-rtos-sdk 2d11c90
- toolchain-xtensa-lx106-elf 5.2.0+100
To compile project see README.md

The README goes on to say install CMake, install GNU Make, rename src to main, build project using idf.py…

So - then to build a project, it is no longer using PlatformIO…? I have to use this same CMakeLists.txt file in every Project? Then what was the purpose of the WallaceWilliam Platform?

I’m confused…

[WallaceWilliam]

Greetings.
the build script is getting harder. with every new version of RTOS the script changes.
I don’t have the time to make changes to maintain platformio, and I don’t see the point of why.
but I'm used to working in VSCode. that's why I made such an opportunity for myself.
I apologize if I did not live up to your expectations.

[WallaceWilliam]

in fact, vscode is used as a text editor

[mriksman]

Sorry, I didn't mean to sound ungrateful. I'm just confused as to what your platform provides.
So from what I can gather, right now it essentially just downloads the SDK and the toolchain.
But everything else needs to be installed/configured/used based on the ESP-IDF installation instructions (CMake, Ninja, etc).
Are there any other benefit your platform provides that I am missing?

[WallaceWilliam]

the project in its current state has no advantages

[maxgerhardt]

Maybe a approach like the platform-espressif32 and ESP-IDF build script can be taken -- instead of re-implementing everything in Python, call into the native CMake environment (https://github.com/platformio/platform-espressif32/blob/e542df17d188a4545965ca8bafe6d0882e31d1c0/builder/frameworks/espidf.py#L631-L640). That is very robust against changes.

@ivankravets This topic of an outtdated ESP8266-RTOS-SDK has also appeared in https://community.platformio.org/t/update-to-esp8266-rtos-sdk/6485 recently

Maybe this is better discussed on the community forum, but I'd like to try and keep the ESP8266 alive and kicking, if there's not too much work involved. The Non-OS version is deprecated, but the version based on FreeRTOS still has potential, IMO.

The ESP32 world is now CMake-driven, it seems, which adds considerable overhead in PIO (in terms of slowing down the edit-run dev cycle), whereas on ESP8266 it's still a very snappy build and upload (1.843 MBaud works fine here). For me, the 8266 offers a way to develop rapidly, while working on code which should also port well to ESP32. And depending on where you're coming from, 100 kB flash + 40 kB RAM free for application code, while having an RTOS-based TCP/IP is pretty useful.

(For reference: I've been doing most of my recent dev work on STM32, and the 1-sec dev cycles are so effective that I really want to get to comparable cycle times on the other systems. On ESP8266-RTOS it's under 5s, which is still very decent.)

any plans for this yet?
