ROC-RK3328-CC 4GB not booting
I downloaded the 16.04 image from 3/9/2018, wrote it to the provided 16GB SD Card using etcher (what I use for my Pi 3 and TinkerBoard), hooked up a HDMI display that works with Pi and TinkerBoard and I get nothing. Normally you would see a bunch of messages as it boots up but I just get a blank screen.
Any ideas?
All I can think of is try again a known good SD Card in case the SD Card is bad.
Should this image show the messages before launching the Desktop like Raspbian and TinkerOS?
Is there an expected sequence for the LED's that might indicate what is going wrong?

Different card didn’t help. I think the problem is that I assumed I could write the image like you do for Raspbian or TinkerOS. Best I can tell it’s more complicated than that but I can’t find instructions and the tool provided with the image (once I got it to display in English) does not seem to recognize the SD Card.
Does anyone have a working set of instructions for creating a SD Card from the downloaded image.
I used etcher it works , usaly boot problem's have been sd card but some
people have had to turn power off restart it on 1st boot if get blank screen
sometimes a few times
@WZ9Vr
Same Issue, 4GB board don't works. Glad to find youre post, so now we are two in a row.
Don't know really what happend but i got it to work for one time. Using gpio pins for powersupply (5V4A) with a switch (on primary stress 220V~). Suddently status was that the board leds (red and green) where off while the powersupply was on. Plugged in sdcard, switched off and on the powersupply, startet booting.
red led = power
green led = board searching for sdcard or emmc (5sec, blank screen). When found green led gets off, Linux is booting (20sec. linux boot screen).
power butten on board was useless?
@jeepthing - I'm using etcher but I have not tried restarting more than 2 times.
@ces - Best I can tell the button is useless.
@WZ9V what resolution are you using
I think the matter is that the board(4GB) immediately goes on when plugging in a powersupply and that the power button is useless. Can't reproduce my success because the board can't be powered off or on with powerbutton.
I think they call it a recovery button, used to enter loader mode

@jeepthing - 1366x768 which is the default for the default for the HDMI panel I'm using.

Thanks for that post.
This might be a stupid question but if you plug your sd card into your computer, does it properly mount?
BTW, just use dd on linux to write the images. The provided image should just work without any issue. You will have to use gparted or resize2fs to expand the image to use all of your sd card but your card should at least boot.
Can you ssh into it? It could be a display issue. The default user is firefly and password is firefly.
Also, if all of that fails, it could be your card writer. Not all writers are created equal, unfortunately.
Problem was the DMT modes being missing in the 3/15 image. I was able to ssh in once I connected to ethernet and figured out the DHCP assigned address.
Ah yes. BTW, this board has UART (console) connectors. You just need a usb to console cable and you can plug it into the GPIO headers. It doesn't help your kernel issue, you will have to compile your own kernel, but it will at least let you know if your board works if you can't get output. Compiling your own kernel isn't too difficult, particularly since firefly gives it to you.
Using the default image, you can replace your kernel on the /dev/sdcard_p4 partition. You might have to mount it first. I recommend mounting that partition it under /boot. Please note that this is different from an ubuntu released kernel where you download the kernel package. There isn't a package for you to download and you have to install it manually. Thankfully, u-boot make this process very simple. I also recommend saving your kernel configuration within the kernel itself. The only reason I might suggest that is because you are not making packages and so it will be difficult to find which config file you used to build it.
In Reference to UART connection i have success with Le Patato board and use: OS Windows 7 64, Putty, Cable RX TX GND, Prolific USB to Serial port (Com 3), 9600,8,1 no Flow no Parity. Happy Serial ^__^
Normally the baud rate is 1,500,000 for Rockchip.
BTW, I never did get it going in the Pi-Top Ceed something about their HDMI conversion in the V1 hub keeps the Renegade from using the LCD. I was going to try the Pi-Top V2 but unfortunately the USB layout is wrong for getting keyboard/trackpad working. That case needs 2 USB where the Renegade only has one. I've moved over to the Le Potato since it has the USB I need and doesn't overheat in this case like the hotter running Rockchip boards tend to do.
