Yes, I can confirm that the " --flash_size=32m " and " -fm dio " options work. Here's what I did: My system is a $200 Intel based Chromebook running Crouton/Ubuntu Linux v.14.04 # Step 1: Erase Flash Memory on NodeMCU ESP8266 SoC: (trusty)randmor@localhost:~$ esptool.py --port /dev/ttyUSB0 erase_fla...

Oh, I didn't see that last post before mine on the second page worth of posts.

So, you say adding "--flash_size=32m" worked for you?! That's great. Let me try that first!

Hi All... I am also having problems flashing the MicroPython firmware (v1.8.7) on to my several Amica Brand NodeMCUs bought through Banggood (a Guangzhou, China based supplier of electronic parts). I have successfully installed MicroPython on several other brand ESP8266 boards including Adafruit Fea...

Thanks Robert. I'll try that as well. Yeah, that worked well! /home/username> cp hello.py /pyboard /home/username> repl Entering REPL.

This can be done using these commands from rshell: /home/username> cat hello.py print("MicroPython is cool!") print("And 'rshell' make...

Hi Guys... I was trying to get rshell to run on an ESP8266 board using what limited docs they had on the GitHub page, but was unable to complete their demo, failing with the "cp hello.py /flash" command. My assumption was that rshell's "/flash" feature probably had not yet been ported to the ESP8266...

Too bad that the folks at Micro:Bit have not spun the Blockly/Scratch like language environment to the public domain so that it could be picked up by the ESP8266 community as their board tend to be a lot more capable than the micro:bit board. There is a Blockly-Duino offering that has been ported to...

Hi Everyone, I was wondering if the "rshell" utility program has been tested or used on ESP8266 Boards like the WeMos D1/R1 board? My problem is that I can not copy files from my Ubuntu Linux machine down to the ESP8266 board. I can run "rshell", and I can do the REPL interactive mode all day long, ...
