Update core to 3.0.0

[ISO-B]

New core version has been released https://github.com/esp8266/Arduino/releases/tag/3.0.0

[maxgerhardt]

FYI until a core update is released (which I don't think will take very long), see this topic for some simple platformio.ini options and test to get the new 3.0.0 core and test out some new features (e.g. the +16Kbyte IRAM heap feature)

[maxgerhardt]

And what did I say? 4 minutes ago changes were pushed to support the latest 3.0.0 core. Waiting for release ^_^

Hi guys, the Arduino and toolchain packages have been updated to the latest 3.0 and 10.2.0 accordingly. Please retest your projects with the upstream version:

[env:d1]
platform = https://github.com/platformio/platform-espressif8266.git
framework = arduino
board = d1

[sblantipodi]

I love those guys! ehm, not in that sense. 😄

[maxgerhardt]

Works flawlessly for me! I also noted that you already extended the documentation with the new MMU features for increased heap, so that it will be displayed at https://docs.platformio.org/en/latest/platforms/espressif8266.html soon, great.

Testing my example linked above with the new platform

[env:d1]
platform = https://github.com/platformio/platform-espressif8266.git
framework = arduino
board = d1
build_flags = -D PIO_FRAMEWORK_ARDUINO_MMU_CACHE16_IRAM48_SECHEAP_SHARED
monitor_speed = 74880

Works exactly as before

IRAM free:  21592 bytes
DRAM free:  52336 bytes

@valeros but is there some command to force the update?
I'm using PlatformIO under CLion IDE and it still use 2.6.3

[maxgerhardt]

Remove C:\Users\<user>\.platformio\platforms\espressif8266@src-xxxxx if the folder exists, to force a redownload. You may have previously used a development version. I had to do this as well. And of course, you will need to use the platformio.ini instructions above with link to the git platform.

@maxgerhardt done it but it redownload the old version:

but if you go here:
https://github.com/platformio/platform-espressif8266/releases
there is no new release.

how those things works? will we see a release soon?

[sblantipodi]

edit: I am trying core 3.0 on my projects, it broke most of the libs I use, most of them are very popular...
it seems that core 3.0 will not be an easy transition...

[maxgerhardt]

how those things works? will we see a release soon?

They'll probably release it as a new stable new version after it has been tested for some while / no issue reported.

platform: espressif8266

If you want to test it you can't use platform = espressif8266 right now but platform = https://github.com/platformio/platform-espressif8266.git as @valeros said above.

it broke most of the libs I use

Which ones? Do the people at the Arduino core already know about this?

[sblantipodi]

Which ones? Do the people at the Arduino core already know about this?

FastLED is the most broken one

[maxgerhardt]

Yeah but per FastLED/FastLED#1236 and FastLED/FastLED#1237 they seem to have been informed about this.

[sblantipodi]

at this point how can I revert to a previous release if they release the 3.0?
is it possible via the platformio.ini?

[maxgerhardt]

Yes as the documentation says you can use any platform-espressif8266 release at any time, like platform = [email protected].

[sblantipodi]

3.0 broke so much things, I hope you'll not release it that soon :D

Updated in the latest release https://github.com/platformio/platform-espressif8266/releases/tag/v3.0.0
