Error when booting esp-wrover-kit dev board at first time :-(

Postby huaxiaozhong1 » Mon Mar 05, 2018 7:35 am

Hi, I have just got an esp-wrover-kit dev board. It reported error when I ran the following steps.
1), Connected it to laptop through USB cable.
2), Turned the board on.
3), Ran "make flash".
4), The following messages were printed out on terminal:"make flash
Flashing binaries to serial port /dev/ttyUSB0 (app at offset 0x10000)...
esptool.py v2.2.1
Connecting........_____....._____....._____....._____....._____....._____....._____....._____....._____....._____

A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
/home/xiaozhong/esp/esp-idf/components/esptool_py/Makefile.projbuild:54: recipe for target 'flash' failed
".
How knows what the issue is?
Thanks!

First of all, do you have jumpers in the correct locations as indicated in http://esp-idf.readthedocs.io/en/latest ... up-options ? Secondly, this board registers as two serial ports; the first one is for JTAG, the second one is the program,ming/debugging port. You can change this in 'make menuconfig', or for a quick fix in your situation, run 'make flash ESPPORT=/dev/ttyUSB1'.

Your answer came really fast actually! I appreciate! I was sending the same question to sales@espressif.com according your Taobao's on-line miss pointed to. But I didn't get any answer yet :-( So I will rely on the forum on the future :-) After I submitted this issue, I found the solution at viewtopic.php?f=2&t=4912, which was here 1 year ago :) So, I have fixed the issue. At the end, I would suggest that a comment can be added into your example codes, to save the starters time :-) But, thank you anyway! And I think that the case can be closed.
