i m using the ESP8266 Wroom-02 ,
i have a problem in using th pin GPIO15 both downloading firmware and after for PWM .in the first case is work fine but for the second case must be attached forevere to GND and then gives me an errore " wdt reset"

ets Jan 8 2013,rst cause:4, boot mode:(3,7)
wdt reset
ets_main.c
for this chip hi is presented 4 channel PWM R=GPIO12,B=GPIO13,G=GPIO15,W=GPO04 my problem for this channel hi is G=GPIO15 because he must work at the two ways but when i tray to attack him to the color G then give an error "wdt reset" thank you in advance

If using GPIO-15 as a PWM, you absolutely must not ground that pin (before pressing RST and putting the GPIO into high Z mode.)
