[Freedombox-discuss] Installation of TT-RSS on Beagle Bone Black Failed But Found a Workaround

[Steven Ng]

I tuned down the VirtualBox memory to 512M and cranked down the CPU power to 50%. In stalled enough applications to use 60/70% of available memory and was able to successfully install TT-RSS.

It took about a half hour to perform this test. I'll adding more applications to use up more memory tomorrow night.
