Would you please send me the "gpio16.c" you are using , support-product@espressif.com

GPIO16 should never have been using these registers.

Hi，

So sorry for the inconvenience，SDK_v1.1.0 release note updated http://bbs.espressif.com/viewtopic.php?f=5&t=481

ESP8266 GPIO don‘t support pull-down function，so related APIs are deleted.

Please add external resistance to pull-down the pin.

Thanks for your interest in ESP8266 !

Yes, I use original SDK 1.0, the gpio16.c is from some other sample project, I will try to remove gpio16.c first, thanks!

Hi ,

Are you using the origional SDK?

It seems there is no PIN_PULLDWN-related register in GPIO16.h

Moreover, GPIO16 is totally different from the other GPIOs(GPIO0-GPIO15), please use the API to control GPIO16.

Note:
There are no pull-down functions on GPIO pad now, so we should never use these registers.
Add external resistance to pulldown the pin.

Yup... They got changed from PULLDWN to PULLUP2 without explanation. I suspect that there isn't an pull-down the chip... In the pin description XLS file the modes are described as reserved. Go figure...
