First impressions of an unwilling board

Astralix

Hi there,

after paying unexpectly high toll duties, I got my board in hands.

I started the board by pugging in USB OTG... but I guess this is not supported, so I connected 5V via USB3 HUB, that provides 2A per port. Even I ordered a board without Wallplug, I got one that is 100-250V but US... Fortunately I do have some adapters ...

The board does not feature a power LED and the fan didn't start too. So I feard my board is defective... I was interrupted by a call when suddenly a blue LED came up blinking! But then I attached serial console and saw that there was an Android booting that either didn't show a logo or was not satisfied with my HDMI TV screen. After unplugging and reconnecting my TV, Android launcher was shown!

As I want to have linux on running on the board, I downloaded the lubuntu 0930 image from here and flashed it using the linux tool...

Doesn't boot...

All in all this is a pretty stumbling start...

What I miss on that board is

- Power LED

- Marking of PCB Revision, to find the correct schematics, PCB and software packages.

- A version of uboot that has the MMU bug fixed or a kernel that takes care of the loaders problem?

- A forum editor where I can set correct line spacings ...

That's so far a report of the first 45minutes with my firefly board

Kind regards

Update:

On the IRC linux-rockchip there has be a hint about a MMU init problem between uboot and kernel. To check for this and updated drivers I ...

Downloaded the SDK mentioned in the wiki and followed the instructions.

Commpiled my own uboot from the SDK:

uboot fetches kernel correctly but kernel fails to boot at the same point where it fails with the original image. So there was something else changed to get from 2014.10-01 to 2014.10-02 version of uboot...

However there was a hint to reset the MMU in the kernel to avoid that crash from the kernel side. Thanks to mmind00!

I cpoied that lines to head.S from kernel and rebuild the image but the result is almost the same:

So still looking around to find a solution.

Hi!




So you're booting an uboot 2014.04 while the latest in the firefly SDK is 2014.10.?

And your uboot claims to not see any PMUs while mine does... This looks like mine is probably setting up something wrong.




It is a bit annoying that there is no prebuild image that you can download that then resets your system into a working state...




We'll see why that is the case...

Hi Andrew!

To find out what is the root cause, the following images are of interest:

- uboot.backup
- recovery.backup
- boot.backup
- kernel.backup (I guess this one is empty)

If you could put there somewhere for me?




However, for the other customers, paying the official price, there should be a downloadable version of the installed package binaries and for the deveoplers there should be a matching source code.

Looks like the firefly-rk3288.dts is incomplete.

At least, after adding a section

memory {
reg =;
};

The kernel boots till setup of framebuffers, before it crashes again:

Hey busybee!

can you please make these latest sources available?

All the guys getting their new boards now at #linux-rockchip are pretty nervous if and how they could restore their original boards if something fails.




Please update the single images, so the others do not get trapped as I was.




Can you please check the schematics for beeing correct with means of voltages?

If I continue to test mainline kernel, I would like to not have random reboots or dead parts due to under- or over-voltage.




And I really need the fully working original uboot sources that you use. That is the first thing, that I need to work on.




That would be really great!

EDIT:

The DualBoot Image works perfectly. There is a small issue with Android and linux according HDMI init. I Android the system doesn't recognize the TV set at bootup, but unplug and replug the HDMI cable shows Android Launcher immediately. Perfect!




The Linux does not accept the HDMI connected TV too. On the console you can see that it has some trouble to read the EDID data:

root@firefly:~# [ 2015.418974] [EDID] extensions block checksum error
[ 2015.419019] rk3288-hdmi ff980000.hdmi: [HDMI] parse edid block 1 error
[ 2015.419042] rk3288-hdmi ff980000.hdmi: warning: EDID error, assume sink as DVI !!!!

To solve that problem, one can chec, which modes are supported by

root@firefly:~# cat /sys/class/display/display0.HDMI/modes

auto
3840x2160p-60
3840x2160p-50
3840x2160p-30
3840x2160p-25
3840x2160p-24
1920x1080p-60
1920x1080p-50
1920x1080p-30
1920x1080p-25
1920x1080p-24
1280x720p-60
1280x720p-50
1280x720p-30
1280x720p-25
1280x720p-24
720x576p-50
720x480p-60

Then select one that matches the TV or monitor resolution:

root@firefly:~# echo "1920x1080p-60" > /sys/class/display/display0.HDMI/modeThe picture will show up immediately










So good news is, that there is a way back to a fully functional preset if one messed up with images and kernels. Great!




Kind regards

Ok, the fun has only lasted short time...

While just showing a youtube overview screen, the board rebooted and is again trapped in a boot loop.

It is the unmodified DualBoot v0930 image.

EDIT:

As I got a US power supply, I used the USB adapter cable connected to a USB3 HUB that is powered by a 5A supply.

This doesn't work... I used some test cables from the lab to do a flying adaption of US to Euro (don't try this at home!) and it boots again into Linux or Android.

So, if you encounter same problem you should try to change the way you supply power to the fly

EDIT:

The FAN is labeled 5V so I connected it to the 5V labeled upper contacts of the right extention port. What I didn't see was, that there are two contacts labeled FAN+ / FAN- at the lower end of this port. Using these pins while again supplying power with the USB adapter cable, it works more stable. Still testing this.

It looks like the fan introduces too much ripple into the 5V power train if it is connected to the upper 5V pins.

So the correct connection of the fan should be mentioned in the starter guide under a chapter mechanical assembly?

Hey again,




It is now definitely clear: You need to keep care that you use a good power supply.?

A 3.5A USB HUB does not work reliable. Even on a USB3 HUB it may give random reboots.

I used lab cords to adapt the 5V/3A US power supply delivered with the firefly and now all images of 2014-11-11 and 2014-12-11 do work without obvious problems.




So firefly team, please check the schematics, the FAN+/- pins on the right connector are not mentioned anywhere else again. So where are they connected? Can the fan be turned off on power-down or can it be regulated by PWM?




And please add precise tags to the git repository at bitbucket so people don't have to guess which version will work and please check the inconsistency between the voltages mentioned in the schematics and the rk3288-firefly.dts.




Please add these findings to the wiki so other people do not run into the same trap.




After a short test with Ubuntu, I can say that this board looks like a really nice piece of hardware and I hope I find enough time for testing in the next days...
