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:

That's the U-Boot as shipped with the device. The shipped Ubuntu worked OK.

I can also build and boot kernel's from the Firefly SDK. I'm cross compiling

under x86-64 Fedora 20 with gcc 4.9.1

Currently I'm trying to get current mainline running. Using linux-next + some

patches and naobsd's firefly device tree, the kernel is getting as far as trying to

mount the root filesystem but is failing as it seems the eMMC isn't getting set up

right. But things seem to be moving in the right direction at least.

Cheers,

Andrew

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...

One of the things I did before tinkering was to backup all

the partitions, so I have :-

Would for example the uboot image be useful to you?

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:

OK, sent info in an email...

busybee

Hi Astralix, please try the dual firmware file in Google drive:

  https://drive.google.com/folderview?id= ... =drive_web

, which is listed in http://www.t-firefly.com/en/download/ .

I check your kernel version and conclude that you are using the old firmware file.

About u-boot, v2.17 and above is good for use.

Astralix

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
