OPP values are adapted from Radxa's downstream kernel for Rock 5B [1],
stripping them down to the minimum frequency and voltage combinations
as expected by the generic upstream cpufreq-dt driver, and also dropping
those OPPs that don't differ in voltage but only in frequency (keeping
the top frequency OPP in each case).
Personally I think OpenWrt is more standard Linux than Armbian which is tons of copy & paste and mix this and that at random. OpenWrt Linux kernel is nearly mainlin one, Armbian is not.
Went to the Raxda website and used this tutorial to install OpenWRT on eMMC, since I don't have a sdcard
If you change the language to english in the config.ini (to 2) it will be much easier, took about 5mins to flash OpenWRT on it, no need to erase anything.
According to this post flashing to the EMMC does not require that procedure
But it’s good to know it works in case no sdcard available
I would have to test that once the stable release is out.
I think now that the smoke is clearing and we have a better idea of the way to get (pure) OpenWrt running on the E52C, we should document this of the wiki page, which is currently very bare:
I have tried to turn off all the lights on the e52c but the port lights are still on and so is the sys green led. I’m running the latest version of snapshot. Has anyone had success turning off all the lights?
I can’t see any extra options in luci to turn off any other leds.

Also I am trying to use a USB 3.0 ethernet adaptor. I am getting the following in the system log
usb usb2-port1: Cannot enable. Maybe the USB cable is bad?
I have installed kmod-usb-net-rtl8152 which is the same driver I used for this device on another openwrt device successfully.
I plugged and unplugged the device and this seemed to work. However the device stopped working again and I see this in the log
kern.warn: [ 2288.308553] xhci-hcd xhci-hcd.3.auto: WARN: HC couldn't access mem fast enough for slot 1 ep 6
kern.info: [ 2288.309337] r8152 2-1:1.0 eth0: intr status -63
I just received one of these devices today. It is so small compared to my Raspberry Pi 5. I have the latest snapshot installed on the EMMC using the rkdeveloptool, the EXT4 snapshot version. I ran into a problem. I am trying to expand the partition but on this snapshot I am unable to install Parted. I am getting an error due to this. It cannot find parted but I know its there, I can see it at the packages site but the link to the .adb is messed up or something on this snapshot. in fact I can't install any other of my normal packages due to this.

basically for the partition you want to resize, you go into fdisk press p to show the start sector of it, then d delete it, and then n make a new partition at the same start but then make it as large as you want if you get any prompt to delete filesystem data say no
then you can use resize2fs to grow the actual filesystem into the partition you just increased the size of
I guess this doesnt help if you cant get access to those tools either
I came from a blank slate. I didn’t upgrade from any RC releases. I used the latest snapshot from here, scroll down to E52C. I used the EXT4 and expanded it using the Openwrt wiki.
