Has anyone managed to install OpenWRT (not flippy or istoreos) on RADXA E54C?
Yes, but only on Sdcard, not NVME. I am struggling with updating SPI bootloader. Looks like SPI is not visible in Linux.
I thought OpenWRT does not support E54C yet. How did you manage it?
Oh, my bad. I thought that you are talking about Flippy Openwrt (I am fast reader 
). OpenWRT from openwrt.org is not supported AFAIK.
You should enable the SPI flash under linux with rsetup, check:
Thank you, but I was following this guide. Problem is that it’s not up to date. It took me several hours, but finally I was able to boot from NVME.
First of all, spi.img is no longer needed. Second “Enable SPI flash” is not available in Manage Overlays in rsetup utility (I have 2GB RAM version without eMMC, but I dont think that its the reason). And finally, after system image copying to NVME, it is necessary to fix GPT table in fdisk, because without that system was not booting.
And my sdcards was not helping either. I was able to finish system update only after I replaced sdcard, twice 
And without system update it is not possible to write SPI bootloader, because SPI device is not visible in /dev in older system version.

Hi!
Can you share details about your setup?
What and how did you set it up.
Thanks in advance.
Downstream LEDE(kernel 6.12) added support for E54C and other Radxa network computers.

Hi. I am having the same problem with my Radxa E54C. I have successfully upgraded the system, but even after that, I am not able to see the famous “Enable SPI flash”. Did you make something else apart from upgrading the system?
Thanks in advance.
Just now, I have been able to boot from NVMe. What I did:
-Flash the SPI using the rsetup. NOT WORKING. I was not able to see “Enable SPI flash”.
-Flash the SPI using RKDevTool on Windows. NOT WORKING. I was getting some errors.
-Flash the SPI using RKDevTool on Linux. SUCCESS.
After flashing from linux, I booted from MicroSD, I made a lsblk and was not seeing any “SPI Flash device” so I had no hope about it. Anyway, I removed the MicroSD card, turned on the Radxa E54C, and VOILA. I saw Debian booting on the monitor. I triple checked that there was no MicroSD card. I also made a lsblk to see “465G part /” and confirm it.
I also want to say that I flashed the OS image connecting the NVMe to my laptop using an external NVMe USB-C case and flashing it with balenaEtcher.
