Hello guys. How do I go about doing that? The oneNAND is much faster than the eMMC so I want to put my /swap there as I'm tired of having my device slow down to a crawl whenever something has to move between the ram and the /swap partition on the eMMC.

I was also thinking on those terms. Repartition UBIFS, make a 64MB swap space. And add it with swapon to the existing swap space.
Adding the oneNAND in parallel to the eMMC should allow 2x read write throughput to swap.

What I have figured out that when the swap size reaches ~200MB thats when things come to a grinding halt.
