 >You're definitely looking at a **custom build**, but it can work for **basic** stuff. This is simpler than using extroot, which has the problem that the filesystem driver etc still must be in internal flash. Also its kind of pointless to have a bunch of large packages (VPN, etc.) stored in extroot but no RAM to run them on. >You're definitely looking at a **custom build**, but it can work for **basic** stuff.
