NanoPi R5C - Rockchip RK3568B2 - 2 PCIe 2.5Gbps

I used this information on a R2S for resizing the squashfs partition (and use the rest): http://

should be the same for the R5C.

Does the data survive a sysupgrade ?

wtuppa · 2024-09-17T19:45:29.160Z

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.

drut · 2024-09-17T20:07:09.821Z

but as far as I understand, there's a chance that in stable release R5C will have proper partition size?

Ahoj,

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.

Regards!

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?

Ahoj,

thanks for this, @fakemanhk.

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.

I have the possibility to get for cheap (used condition):

~~Intel 7260NGW (g/n/a/c) (with bluetooth)~~ (Seems that it can only advertise one SSID as access point)
Intel 3168NGW (a/c)
Intel 9560NGW (with bluetooth)
Intel AX200NGW
Intel AC 8260NGW
Intel 18260NGW
Realtek rtl8723be nf (b/g/n) (with bluetooth)
MediaTek MT7921

Does anyone know if they support multiple SSIDs in AP mode in OpenWrt, or how to find out beforehand?

Regards!

You can remove all Intel/Realtek entries from the list if you want AP mode.

It advertises multiple SSIDs, but as soon as there is more than one my laptop (client) cannot associate with the WPA/WPA2 encrypted WiFi (with unencrypted network, association works).

Maybe a recompilation of kernel/ newer kernel could work(?).
I use FriendlyElec's "FriendlyWrt", kernel version: 6.1.57.

I am going to switch to mainline OpenWrt as soon as r5c support is in stable (currently it is in daily snapshot; I just refrain from using it because the opkg package repository most probably will not stay compatible). Then maybe also building locally.

So, in the end I regard the discussion as "pre-information" for when I switch to mainline OpenWrt.

maurer · 2024-11-10T06:34:20.766Z

You can start using https://downloads.openwrt.org/releases/24.10-SNAPSHOT/targets/ as opkg will stay compatible with all 24.10.x versions

openwrt.org/releases/snapshot says contrary to your statement

snapshots are built daily, and that sets time limits to installing new packages with opkg. Due to kernel version checksums, you can only install “kmod” kernel modules and other kernel version dependent modules from the exactly same snapshot build. So, a few hours after flashing the firmware you may not be able to install new modules with opkg any more

maurer · 2024-11-10T19:01:22.078Z

anyone can request a wiki account and update it accordingly - kmods are kept for around 4-5months these days - see Index of /snapshots/targets/rockchip/armv8/kmods/

If one knows. I take the wiki as the first authorative information. Why should I assume that the information is not correct?

maurer:

Thanks, regards! (This still gives a few months only, something I do not really wish, but better than what is written in the wiki.)

I have an account, I am logged in, but I do not see any way to edit openwrt.org/releases/snapshot. Where on other paged there is the "edit" symbol, I just see the "view source" symbol:
Contrary, openwrt.org/toh/friendlyarm/nanopi_r5c I can edit:
So in general I have edit rights.
But not for openwrt.org/releases/snapshot.

So, @maurer: Can you update openwrt.org/releases/snapshot, since you seem to know more than what is written there, you pointed me to edit it, but I can not edit it?

let's open a new thread on the documentation section and ask for support there - tbh - I don't have a wiki account
