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?

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

FastLED is the most broken one

[maxgerhardt]

Yeah but per https://github.com/FastLED/FastLED/issues/1236 and https://github.com/FastLED/FastLED/issues/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 = espressif8266@2.6.3.

[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
