Hi,

Espressif Systems Developer might see this thread and can reply as I know this community is not handled and controlled by Espressif Systems Developer.

Regarding NonOS SDK, We are right now using ESP8266 RTOS SDK 1.5.0 for our minimal firmware requirement in which we need following stuffs as support

    WIFi AP Mode Access
    TCP Server to get Data from APK
    SPI Flash Access

See also https://github.com/pvvx/MinEspSDKLib

Obviously requires more effort and you won't be able to use standard libraries.


Hi,

Thanks for providing useful informations. I will check it and will let you know if need any help regarding porting or other stuffs for same.

Hi, We have tried with your provided links and following are result with that.

1) https://github.com/pvvx/MinEspSDKLib : Using this link we have created firmware as per our flash memory requirement and loaded firmware into our board as well. but board not started after that.

2) https://github.com/cnlohr/nosdk8266 : it will create also 240 Kbytes firmware with sample code.

So, Did you try to create minimal firmware?
