I’m Stuck - Really, stuck


I am completely unable to upload any firmware to my HUZZAH feather ESP8266
I used the advance checklist from https://arduino-esp8266.readthedocs.io/ ... ailed.html


Initial Checks

[YES ] Is your module connected to serial port and visible in IDE?

[YES] Is connected device responding to IDE? What is exact message in debug window?

[YES ] Have you selected correct ESP module type in Board menu? What is the selection?
BOARD=Adafruit Feather HUZZAH ESP8266
Flash Size = 4M (1M SPIFFS)

[from 9600 to 115200] Have you tried to reduce upload speed? What speeds have you tried?

Advanced Checks

[SEE BELOW ] What message is reported by ESP at 74880 baud when entering boot loading mode?
ets Jan 8 2013,rst cause:2, boot mode:(3,7)

load 0x40100000, len 28740, room 16
tail 4
chksum 0xcd
load 0x3ffe8000, len 2888, room 4

chksum 0xbc
load 0x3ffe8b50, len 15252, room 4
tail 0
chksum 0x4f
csum 0x4f


[input = output ] Have you checked your USB to serial converter by looping it back? What is the result?

[NO, SEE BELOW] Is your detailed upload log consistent with settings in IDE? What is the log?
The Device is set f HUZZAH and the log shows nodemcu

Reset Method

[N/A] What reset method do you use?
[N/A] What is your connection diagram? Does it match diagram in this FAQ?
[N/A] What is your wave-form of board reset? Does it match wave-form in this FAQ?
[N/A ] What is your wave-form of complete upload? Does it match wave-form in this FAQ?

Software

[YES = 1.8.8 ] Do you use the latest stable version of esp8266 / Arduino? What is it?
[IDE = 1.8.8 MacOS=10.14.3 beta ] What is the name and version of your IDE and O/S?

I don't have any (positive) experiences with Macs, but it wouldn't surprise me if the USB driver doesn't (fully) support the DTR- and/or RTS-lines of the USB-serial chip.
To circumvent such a problem, you can always manually set your board into programming mode by (temporary) connecting a push-button (or a link using a Dupont wire) between GPIO0 and GND (since it seems a Huzzah doesn't have a manual flash-button) and then following the manual programming sequence:

• Press and hold flash
• Press reset
• Release flash

Your board should now be in programming mode and you can program it from within the Arduino IDE.

I tried that. And it did not change anything for me. I still get

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed

Hello, I use Mac os.
I had problems also to install my driver (node mcu).
That a year ago.
I remember needing to search well for drivers for nodeMcu.
Maybe this is your problem.
Check the chip that you use, search a little about the driver and how to install it on your Mac.
I remember installing 4 types of drivers to make it work.
Remember to restart your computer after installing the drivers !!
Hope this helps!
