1MB of the flash is used as a swapfile and creates virtual RAM space to the emulation through a MMU caching system

That sounds like it would wear out the flash very quickly, especially given that the embedded flash on MCUs like these are not really designed for much in the way of write cycles (the usual case being firmware updates and configuration changes, both not high-frequency operations.)

Interesting hack nonetheless, it reminds me of this: https://dmitry.gr/?r=05.Projects&proj=07.%20Linux%20on%208bi...



Yeah, it’d almost be better to use SD for virtual memory to at least put the flash wear on something consumable.


> something consumable

ESP8266s can be had for ~$1...


On the other hand ESP8266 is probably cheaper than as SD card


Maybe not run this in mission critical production systems
