ESP8266 SDK22x_191024 does not work reliable with old Xtensa Build chain

[Jason2866]

• PlatformIO Core.

Please update Xtensa build chain for ESP8266 to latest 2.5.x version for feature/stage.
The newer Non Os SDK versions 2.2.2 from 191024 and 191105 does NOT work
reliable with the the used build chain.

When compiling Tasmota with the Xtensa Build Chain 2.4.x there are wifi reconnects.
Using Xtensa Build chain 2.5.0.4 solves this issues.

I have done a custom setup (dirty hack for windows) to use the 2.5.x version.

Hi,

Core 2.6.0 has been just released but requires to update toolchain to 2.5.0-4

Using previous toolchain (2.4.x) produces firmwares that have wifi disconnections for ESP8266 devices.

Thanks.

Core 2.6.1 is released
@TD-er You can use with

Hi @ivankravets pls give this priority as I would like to release Tasmota one of these days using a stable platformio environment

Thx in advance.

Could someone summarize what should be done from our side? We have support for Arduino and native SDK. Is the new compiler compatible with SDK version which we support? Or, the new toolchain should be used for new Arduino?

@ivankravets Release core 2.6.1 as platformio-espressif8266 package with Xtensa build chain 2.5.0.4
The new SDK version SDK22x_191105 does solve many issues but requires Xtensa build chain 2.5.0.4.
If the older build chain is used it generates wifi issues
