¶ OpenWrt on 8/64 devices
/******
8/64 warning describes the background of the 8/64 problem (theory). In contrast to the 864 warning, this page here shall describe what users can actually do (praxis).
This page has intended similarities to openwrt_on_432_devices, but may differ in some details.
******/
You have a device with 8MB flash and/or 64MB RAM.
You have read and understood the 8/64 warning.
You have adjusted your expectations according to this warning.
You still want to install OpenWrt on your 8/64 device for
- training purposes only (soldering, OpenWrt, Linux in general); if it breaks, it breaks, it's no loss.
- basic, low level routing functions only
Now you are asking: What can I do?
Find answers below.
¶ Which release shall I choose?
/* This section may differ from the 4/32 page since 8/64 devices are not as restricted as 4/32 (ORLY:) */ /* More flash space available means newer OpenWrt release can be chosen than on 4/32 devices. */ /* For the moment, just include this section from the 432 page. Make it specific to 8/64 later on if needed. */
¶ 8MB flash issue
How can I work around the 8MB flash issue?
- build your own image 18.06/19.07 image with all possible space saving measures, or...
- ...use extroot (only if USB available)
- no flash problems any more
- "infinite"[1] storage space available
- install all the packages of the world, if you like
- BUT: It's kind of pointless to have a bunch of large packages (VPN, etc.) stored in extroot, but no RAM to run them on.
Why should I build my own image rather than installing packages?
Building your own image compresses the packages you need to about half the size compared to installing them after you flash.
¶ 64MB RAM issue
How can I work around the 64MB RAM issue?
- Don't use LuCI (will not work at all, will be terribly slow, or will crash due to OOM)
- Don't use RAM hungry applications (will not work at all, will be terribly slow, or will crash due to OOM)

¶ Community builds
Check out the community Builds section of the forum. Maybe someone created a special build which takes care of the 8/64 specific issues.
4GB USB stick instead of 8MB built-in flash can be considered as infinite. ↩︎
