Re: Can't flash 1.8.5 (or 1.8.4) on NodeMCU

I was trying all this on my surface machine. Today, I switched to a mac and tried again and on the second try it worked. I don't know why I am able to flash the lua firmware using windows but not the micropython one. Thanks to everyone here. This community is awesome! PS: Will keep investigating wha...

Re: Can't flash 1.8.5 (or 1.8.4) on NodeMCU

What is the real flash size of your flash ROM? The discussion does mention settings from 8mb to 32mb for esptool. If your modules have only 512KB of flash this might be of interest to you: A few weeks ago the MicroPython builds did exceed the initially set 512KB flash barrier. pfalcon did introduce...

Re: Can't flash 1.8.5 (or 1.8.4) on NodeMCU

I noticed that erasing the flash doesn't do much when the board gets stuck like that. What worked for me is flashing a different firmware (nodemcu or espruino), and then flashing MicroPython on top of that. I have no idea why that happens -- a flash dump after erase_flash returns all 0xff, so seems...

Which version of esptool?
Hi, I tried both fs 32m and 8m, same results. I am using esptool 1.1 on windows (This used to work). I can flash the nodemcu lua one without problem tough.

thanks for the reply.

Can't flash 1.8.5 (or 1.8.4) on NodeMCU

Hello Friends, I am having a lot of trouble flashing micropython 1.8.5 (or 1.8.4) firmware to my NodeMCUs. Some months ago this worked fine with the same boards. Now, the flashing happens without any error but upon reset the LED blinks like mad and garbage is spewed to the screen non-stop. The same ...

Re: Initial Setup via AP

Hey Friends, First post here. I just built a captive portal for MicroPython and the ESP8266. Basically it has a hijacking DNS server and a Web server in the same loop so that it can trigger the Web interface. In this demo, I have an RGB LED attached to ports 5,4,0 and the Web interface allows you to...
