"MemoryError:" when trying to run it on an ESP8266 NodeMCU breakout #12

How can I get over this error?

The approach to running large modules on RAM limited devices is to use frozen bytecode. Put the MicropPython modules into ports/esp8266/modules in the source tree. Then rebuild the firmware and install. This causes the MicroPython code to be compiled to bytecode on the PC; on installation the bytecode is stored in Flash.

Thanks for your reply! However I'm a newb when it comes to uPy. Till now, to install the firmware, I've been directly using esptool.py and the bin files from the micropython downloads page. How do I rebuild and install the firmware as you mentioned?

A starting point might be to read the build document.
