Orange Pi 4

Recommended Posts

Hey folks,

 

I ordered an Orange Pi 4 a couple weeks ago, and it showed up on Wednesday.  Last night I started tinkering around with to see if I could get Armbian up and running on it.  First thing I did was to hook up my USB-to-TTL debugger to it (no SD card inserted).  But when I powered it on, all I'm getting over the serial connection is garbage.  With my other OPi's, I'm used to getting U-Boot messages -- but this was far from that:

The garbage settles down after about 30 seconds.  When I have it hooked up to my Windows machine, I get a new device called "rk3399-mid" that appears in device manager.

 

I tried grabbing the image for the OPi RK3399, flashing that to an SD card, and trying to boot from that.  I still get garbage, it takes less than 30 seconds for things to calm down, and I don't get any device showing up in device manager.

 

So the question is, has anyone else run into this?  If so, what do you do about it?  Or do I maybe just have a bad USB-to-TTL debugger?

 

Edited to add: Let me just say that Xunlong's manuals aren't much help here w.r.t. figuring out how to hook up the TTL lines.  (They show a picture where they've labelled which pins are which, but the labels are all in Chinese -- and I'm a stinking monolingual American.)  But I was able to figure out which one was the ground pin by looking at the traces on the board/using a multimeter.  As far as the TX/RX lines -- the configuration I have them in is the only one that produces any data at all:

Which baud rate did you choose ?

All RockChip SoC are defaulting to 1500000 baud ...

 

EDIT : Sorry, I didn't look at your screenshot right ...

So, maybe the eMMC has Android installed by default and choose a different baud rate.

This Android U-Boot maybe doesn't provide option to stop and boot from eMMC.

 

EDIT2: To boot from SDCard, you will have to find TP50265 and TP50272 test points and short them together, that will disable the eMMC.

Yay! /s

 

Ok, let me give that a shot.

I've done that the first time I got OrangePi-RK3399 using a twesser, holding it carefully, while pluging the power.

Once Armbian U-Boot is installed on eMMC, you won't need to do that again, since this U-Boot allowed to be stop at command prompt, you can then switch to SDCard using "setenv devnum 1; run mmc_boot".

I've not done it on OPi4 since I didn't received mine yet ...

No luck.  These are the two contacts we're talking about, right?  (Stole this from Xunlong's manual)

Also, damn, it's hard to hold a pair of tweezers on those two contacts...

 

I've also cycled through every baud rate my TTL adapter supports with no luck.

I don't know since I didn't received my board yet ...

The important test point is TP50265, the other one is GND, but GND could be find elsewhere.

So, you can get an alligator cable attach to some other GND and on the other end use an attached needle to touch TP50265.

Ok...so the verdict is I have a bad TTL adapter.

 

I have a Rock64 and some jumper wires, and the Rock64 has a UART on it capable of running a 1500000 baud...so I wired up the debug pins on the OPi to the UART on the Rock64 -- and bam, I get stuff that I can at least read.  (The only bad thing is that the Rock64 leaks voltage out of the UART pins...so the board tries to power on as soon as you hook it up.)

 

Without the SD card?  I think you're right -- it tries to boot into Android.  I see a bunch of messages from the kernel, and then it drops into a shell.  (Interestingly, it also spits out a bunch of errors b/c the filesystem is read-only...but whatever.)

 

With the SD card?  Here's what I get:

BTW -- I didn't have to connect TP50625 to anything to get it to boot off the SD card.

 

So...next step -- maybe try to build a new U-Boot?

Are you sure that the above log is coming from SDCard U-Boot and not from eMMC U-Boot ?

Because eMMC has the priority against SDCard ... Except if you short TP50265 ...

Maybe I'm wrong, but on all the RK33xx I've seen, the priority is SD card over eMMC. The primary idbloader is taken from eMMC and everything else starts using from SD card.

Doesn't work that way on my two OrangePi RK3399, but it's that way on my Renegade Elite.

It is interesting to look at the implementation of this option. Show the system startup UART log from eMMC (without SD card connection) and the second system startup log from SD card.

That is why ... If the original primary idbloader isn't looking at presence of SDCard, there is no other choice of disabling the eMMC.

I have not seen such an option yet (blocking the launch exclusively for eMMC). So I am interested to look at the UART log with such a lock.  :)

Sorry guys...got locked out of my account :-)

 

So...no, I'm not sure that the log is coming from the SD card specifically.  All I know at this point is that the board behaves differently with an SD card vs. without one.  Without one, it boots into (what I'm assuming is) Android.  With one, it prints out the log I posted earlier and then freezes.

I got mine too. Run debian & ubuntu using orangepi image. Got no display from hdmi although the os boot up and running :(

After some tests,  I think orangepi image not supporting wide screen monitor.

hdmi - wide screen monitor : no display

hdmi - 16-9 monitor : ok

hdmi - dvi-  16-9 monitor  : ok

hdmi - vga -  16-9 monitor  :  no display
