I experienced a lot of upgrading issues in the past when expanding the rootfs, resizing the parition of using overlay (I was using rpi3 and sdcard, but the problems remain the same).
So, my advise is to create a 3rd partition, but a little away from where OpenWRT reside (first sector = 524288). Then install block-mount and configure /dev/mmcblk1p3 to mount to /opt
I used this information on a R2S for resizing the squashfs partition (and use the rest): http:// www.doorxp.com/?id=142
should be the same for the R5C.
after sysupgrade you will no longer see the data. you have to redo the whole procedure.
and after the partition layout is the same again, data in the extra partition will survice a sysupgrade. It worked for me already one time with a 64GB SD card.
I now also got a NanoPi R5C with the default WiFi card built in by the vendor, which should be a RTL8822CE.
Does the card really not support multiple ESSIDs (neither as access point servicing multiple networks, nor acting both as WiFi client on one network and access point on another network)?
As soon as I created more than one wireless network, wireless did not work.
Using an USB wireless network adapter I could create several wireless networks on that adapter -- but not on the internal one.
Is this an hardware issue, or a kernel or userspace configuration issue?
Which m.2 WiFi card(s) are recommended for multiple networks and preferably also acting as client and access point (and maybe mesh/ ad-hoc?) at the same time?
5 GHz/ 6GHz and high data rates are not required. 20 Mbit/s Wireless is sufficient, 50 Mbit/s is good.
For any devices not targeting AP usage (basically all USB WiFi, and many of the internal WiFi cards are under this category) you'll see different behaviors when trying to run AP mode, this is normal since they are designed as client, on AP mode YMMV. And especially if you want to create dual band (2.4GHz + 5GHz) it's basically not possible at all.
For AP usage, MT7915/MT7916 are designed for that, however I would prefer to separate it because you also need a well designed antennae system to have great signal coverage, together the cost is high.
With this requirement why not getting GL-INET Shadow (AR300M/AR300M16)?? Way cheaper solution.
Hi, I flashed the snapshot vanilla OpenWrt on my R5C, set DDNS and a WG Server, everything was perfect, rebooted the device several times with no issues. Now I plugged the device back again, and it just doesn't turn on, not even the LEDs, I don't know what happened, the device gets warm after a couple of minutes so it seems like it's working but bricked in a few words, has anyone had this issue?
I do not nead "great signal coverage". Just a single small room. But multiple SSIDs preferably without any external USB WiFi-adapter, and optional but highly preferred to be in client mode and AP mode at once (on different SSIDs).
I want the computational power of the device, I want the "play-with-it"-ability of the device, and: I already have it.
