Accessing FlashROM

by headphones54321 on Wed Dec 07, 2016 4:03 pm

The Huzzah is reported to have 4MB of FlashROM in addition to the 512kB Flash memory. How do I use this memory? I can't seem to find any documentation. Is it used by default for the filesystem? If I write data to a file, is that using the FlashROM?

Thanks

Short answer, I believe the filesystem does use the external FlashROM its shared with the code too.

Long answer, its complicated and I don't fully understand it. However, I know theres an exhaustive post on the ESP8266 MicroPython Kickstarter page all about it here.

Hope that helps.
