Hi guys,
I got a Nano32 board from rudi;) and try to use it with Arduino IDE 1.6.12; Win10
Followed the instructions http://microcontrollerkits.blogspot.de/ ... o-ide.html
Fixed the first problem "no module named serial" http://www.ayarafun.com/2016/10/arduino ... rst-touch/
but can't get the blink example to upload.
Settings:
ESP32 Dev Module
Flash 40MHz
upload speed 115200
Programmer AVR ISP
Code:
#define LED 16
void setup() {
pinMode(LED, OUTPUT);
}
void loop() {
digitalWrite(LED, HIGH);
delay(1000);
digitalWrite(LED, LOW);
delay(1000);
}
Error Message:
esptool.py v2.0-dev
Connecting...
Uploading stub...
Running stub...
Stub running...

Unc size 4016 comp size 2616 comp blocks 3
A fatal error occurred: Timed out waiting for packet content
Module has green and yellow LED on steady
I tried already to use Nano32 board, and different speeds but no difference.
When I use the serial monitor with 115200 baud there is a lot of 'traffic' with constant reboot.
Green LED on, Yellow off, red blinking
What am I doing wrong? Please help
Timed out waiting for packet content
Re: Timed out waiting for packet content
It seems that the board is not getting reset into download mode by esptool. Can you try holding GPIO0 low while programming the board?

Re: Timed out waiting for packet content
Tried to short press GPIO0, also long press, also keep pressed, also keep pressed and press EN, all versions.

Until I disconnect the module I get then the message "Timed out waiting for packet content"

Re: Timed out waiting for packet content
I believe this was due to flash status register bug and was fixed recently. Do you have latest updates to esp-idf and submodules?GyroGearloose wrote:A fatal error occurred: MD5 of file does not match data in flash!
