just got the sparkfun esp32 board, tried:

esptool.py \
--chip esp32 \
--port "tty.usbserial-DN02MZEH" \
--baud 115200  \
write_flash -z  \
--flash_mode "dio" \
--flash_freq "40m"  \
--flash_size "2MB"  \
0x1000 bootloader.bin 0x10000 \
app-template.bin \
0x8000 partitions_singleapp.bin

and got:

usage: esptool [-h] [--port PORT] [--baud BAUD]
               {load_ram,dump_mem,read_mem,write_mem,write_flash,run,image_info,make_image,elf2image,read_mac,chip_id,flash_id,read_flash,verify_flash,erase_flash}
               ...
esptool: error: argument operation: invalid choice: 'esp32' (choose from 'load_ram', 'dump_mem', 'read_mem', 'write_mem', 'write_flash', 'run', 'image_info', 'make_image', 'elf2image', 'read_mac', 'chip_id', 'flash_id', 'read_flash', 'verify_flash', 'erase_flash')

note: the board and port work fine with the arduino-esp32 libraries.

Assuming you are using the binary download of ESP32-Duktape, there should be a shell script called "install_binaries.sh" which contains the command necessary for flashing the ESP32 with duktape. The copy I see shows:

#!/bin/bash
#
#  Script to install the ESP32-Duktape images into an ESP32.
#
#  For faster transfers that *may* be less reliable, change the baud
# rate to 921600.
#

PORT="/dev/ttyUSB0"
BAUD="115200"

set -e

if [ ! -z "$IDF_PATH" ]
then
    ESPTOOL=$IDF_PATH/components/esptool_py/esptool/esptool.py
fi

if [ -z "$ESPTOOL" ]
then
    echo "Could not find esptool.  Make sure that IDF_PATH is set"
    echo "to the root of your ESP-IDF install"
    exit 1
fi

python $ESPTOOL  \
 --chip esp32 --port "$PORT" --baud $BAUD  write_flash --flash_mode "dio" \
 --flash_freq "40m" --flash_size "4MB" --compress \
 0x1000   bootloader.bin \
 0x8000   partitions_singleapp.bin \
 0x10000  esp32-duktape.bin \
 0x180000 spiffs.img \
 0x360000 espfs.img

When I run esptool -h I see the following:

usage: esptool [-h] [--chip {auto,esp8266,esp31,esp32}] [--port PORT]
               [--baud BAUD] [--before {default_reset,no_reset,esp32r0}]

Note the version number of "v2.0-dev". Can you check that you are using the latest version of esptool as supplied with the ESP-IDF SDK?

Thanks Neil, I probably should update esptool too, it's probably out of date. Dave

nkolban commented 7 years ago

David ... feel free to drop me an email at kolban1@kolban.com ... I'm really keen on ESP32-Duktape and want to chat with users to make sure all is working for you and to hear about areas that can be improved.

davidmoshal commented 7 years ago

@nkolban SUCCESS!

I spent a little time this morning on the project and managed to flash the ESP32 successfully from OSX!

Steps:

  1. installed esp-idf using this page: http://esp-idf.readthedocs.io/en/latest/macos-setup.html

specifically:

dowloaded:
https://dl.espressif.com/dl/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz

mkdir -p ~/esp
cd ~/esp
tar -xzf ~/Downloads/xtensa-esp32-elf-osx-1.22.0-61-gab8375a-5.2.0.tar.gz
export PATH=$PATH:$HOME/esp/xtensa-esp32-elf/bin

git clone --recursive https://github.com/espressif/esp-idf.git
export IDF_PATH=~/esp/esp-idf
  1. downloaded binaries from this page: https://github.com/nkolban/duktape-esp32/blob/master/docs/README.md

and executed this command with the correct port for my machine:

 $IDF_PATH/components/esptool_py/esptool/esptool.py --chip esp32 \
--port "/dev/tty.usbserial-DN02MZEH" \
--baud 115200  \
write_flash -z \
--flash_mode "dio" \
--flash_freq "40m"  \
--flash_size "2MB" \
  0x1000 bootloader.bin 0x10000 app-template.bin 0x8000 partitions_singleapp.bin

Notes:

  1. As you suggested, originally I was using the wrong esptool.py
  2. Your page: https://github.com/nkolban/duktape-esp32/blob/master/docs/installation.md suggests that these files are needed, yet I was able to flash without them:

Note: the above information is out of date, there is a newer build, 2017-01-20, which has an ./installbinaries.sh file whith the correct flashing instructions, together with the correct binaries.

the command is now:

# change the port to the port identified by: ls /dev | grep tty

$IDF_PATH/components/esptool_py/esptool/esptool.py \
--chip esp32 \
--port "/dev/tty.SLAB_USBtoUART" \
--baud 115200 write_flash \
--flash_mode "dio" \
--flash_freq "40m" \
--flash_size "4MB" \
--compress \
 0x1000    bootloader.bin \
 0x8000    partitions_singleapp.bin \
 0x10000   esp32-duktape.bin \
 0x180000 spiffs.img \
 0x300000 espfs.img
