NONOS 2.0.0 to 2.1.0

[AgentSmithers]

Hi Everyone.
I am using the Wemos D1 Mini Pro and I came across the requirement to get PWM working. So I went into my main SDK directory and modified the Makefile adjusting it from VENDOR_SDK = 2.0.0 to VENDOR_SDK = 2.1.0 and BAM PWM started working perfect without my WD timer kicking off.. But then right when I did that my Wifi stoped working. It seems like everything is perfect but it is no longer hsoting an AP anymore, I then updated my make file back to 2.0.0 then did a clean and make on my project then Wifi starts working then my PWM kicks off a WDT error rebooting my chip. Any qlues? I can reproduce the issue swapping back and forth to make the Wifi or PWM stop working correctly.
Thank you everyone!

*Update* It seems copying the files
libmain.a
libnet80211.a
Libpp.a
esp-open-sdk\lib to xtensa-lx106-elf\xtensa-lx106-elf\sysroot\usr\lib\ makes pwm work in the SDK but then breaks the wifi again as expected then reverting these files again makes wifi work but breaks pwm.

Any pointers would be awesome.
Thanks everyone!

What a strange problem. Not sure if it can help, I think this is an example of both PWM and wifi are using. https://github.com/espressif/ESP8266_NONOS_SDK/blob/master/examples/IoT_Demo/user/user_light.c

Thanks, I also got a response from

It appears that's ESP_COCO was pointing at os_delay causing this bug. Any thought's on that. It seems very very weird why OS_DELAY in 2.1 would break Wifi Hosting on the new SDK vs working perfectly fine on 2.0?

If you make any delay long enough, wifi will break anyway. I don't think you should use them, use timers instead.
