#49626 Hi
I was working quite a long time with ESP1, and trying to move to ESP12 due to lack of gpio ports.
I'm having hard time to run code on the ESP12 and can't understand the problem.
I''ve wired the esp to work on boot on mode 1:
Code: Select allets Jan  8 2013,rst cause:2, boot mode:(1,6)

and uploaded a simple code:
Code: Select allvoid setup() {
  pinMode(13, OUTPUT);
  Serial.begin(74880);
  Serial.println("Hello, world");
}
void loop() {
  digitalWrite(13, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);              // wait for a second
  digitalWrite(13, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);              // wait for a second
}


The upload ends succefully, but when moving to mode 3 (run mode) I get nothing!
Code: Select all
 ets Jan  8 2013,rst cause:2, boot mode:(3,6)

load 0x4010f000, len 1264, room 16
tail 0
chksum 0x0f
csum 0x0f
~ld

By nothing I mean that hooking a LED to pin 13 yields with nothing (constant ON), and even no Serial print!

What am I'm missing!?
