My first post. Just got the board. I had to buy a 9v QC charger. When I plug in the charger the blue LED comes on and it gets bright(QC switching to 9v??). If I wait the green and white radxa X logo flashes for an instant and goes to an EFI Shell prompt.
I tried the Shell map in the wiki and got 3 pci devices." ls" failed on all with no dir.
Not booting Rock Pi X
You need to install an Operating System, usually either Windows or Linux. See the bottom of this page: https://wiki.radxa.com/RockpiX/getting_started
More info. I had the Ubuntu iso on a stick plugged into a USB port. I held the del key. I didnât get the BIOS screen.
I typed some text and edited the text with arrow keys and the delete key. The delete key is actually a backspace. I switched to keyboard with separate del and backspace and I got to the boot screen. 
The boot override only lists the RFI shell. I will try other USB ports. Iâm using the blue USB 3 port. More later.
I actually am having similar issues and am curious to see what comes of your testing. I am not seeing my ISO image as a boot option in USB3 or 2 ports
I finally got it to work. I made a USB startup disk on my Ubuntu PC. I used the app called âStartup Disk Creatorâ. Writing the ISO with a âddâ command didnât work. I suspect I needed to partition the USB stick before doing the âddâ. âStartup Disk Creatorâ may handle the partitioning, but this is only a guess.

I am very happy, now. I will wait for the Pi X heatsink to do more stressful apps. Itâs on preorder waiting for parts.
I have the same problem with Rock Pi X⌠I cannot install any system either Win or any other system. I follow all the same procedures as any of my other pcâs or Piâs to no avail. The bios shows the drive I want to boot from but just goes to the Radxa screen whenI choose it. I am powering the unit with my variable power supply to specification but still no joy. The responses I got about this problem seem to tell me I am too dumb to flash the system properly after 30 years of working with pcâs! Maybe I am having a Biden moment?
All systems must use UEFI to boot. Additionally, the boot partition (I believe) needs to be Fat32. This comes with the limitation that you canât simply flash the Windows 10 iso to a USB (Fat32 has a file size limit of 4GB, install.wim is bigger).
To install Windows, one should use Rufus to create a bootable USB.

When I boot, the Radxa screen stays on for a very long time before the Ubuntu screen appears. You may need to wait longer.
Do you mean that a USB stick created with Microsoft Media Creation Tool canât be used? I tried this with Windows 10 20H2 but couldnât boot.
Step 1. Download rufus
Step 2. Download image
Step 3. Use Rufus to burn image into usb
Step ???.
Step N. Profit
I was thinking the same thing. I have a Rock Pi that did the same thing to my amazement. I waited on the X for several hours but nothing happened.
Hmm. I donât have a Windows PC (the Rock Pi X was supposed to fill this gap) so I canât use Rufus. Tried all the suggestions using Ubuntu. No Luck. If I come up with a fix Iâll report back.
Managed to get unetbootin to produce a USB disk that was recognised by the BIOS. Unfortunately it failed to produce a valid copy of install.wim. Itâs also got quite a few bugs. The following command line got it going but I guess I may have formatted the drive wrong as install.wim is the one thatâs too big for fat32.
sudo QT_X11_NO_MITSHM=1 /usr/bin/unetbootin installtype=USB targetdrive=/dev/sdc1
Iâll keep trying
Reformatted to NTFS. Windows now installing.
I will try that. I used Rufus for the Win10 iso on a drive formatted NTFS but it did not work with the Pi-X. I will try again with Unetbootin. (never heard of it)
I have same problem but I found solution.
You need to keep pressing DEL during startup.
When your are in BIOS go to last page âSave and exitâ
Press last option 'Reset system with ME disable âŚ
Make sure you had drives in right boot order.
Restore BIOS defaults didnât help to make it boot again what is strange.
Then it boots in Windows.
All happy and content?
