ESP32 daily firmware builds

Postby rdagger » Sun Jun 18, 2017 10:50 pm

Are there daily firmware builds available for ESP32 boards?
I looked on the Micropython download site but the ESP32 section is empty.

The ESP32 port is a little behind in commits. The download page seems to build on recent version tags, which are missing in that repository.

I guess you might wait for Damien to merge that repository, do this by your own or raise an issue on the ESP32 repository on Github.

I have made a build of todays repository state. You can find it here https://github.com/robert-hh/Shared-Stuff
The filename is firmware.bin. You have to use esptool.py to flash it to the device. The command is:

Code: Select all

path_to_esptool.py/esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z --flash_mode dio --flash_freq 40m --flash_size 4MB 0 build/firmware.bin


A suitable esptool.py is for instance here: https://github.com/espressif/esptool/tr ... 90ff58845f

P.S.: The flash includes a copy of a small ftp server, started with "import ftp", which however serves only the STA mode interface.
It includes also a copy of upysh.py, a set of small file commands, and a small editor called pye.
usage for upysh: "from upysh import *", and then "man" for a list of commands
usage for pye: "from pye import pye", and then pye("filename1", "filename2", ...)

Thank you very much and I will check it out. I ended up building it myself using the Adafruit video.

For reference the Micropython Downloads page has had the ESP32 builds reinstated.

(Thanks Damien!)

Also see the discussion in Issue 91.
