does this give acces to the hdmi input?

i dont know. i have only built this for the original firefly not the firefly reloaded. the original doesnt have hdmi in.
kernel could easily be replaced with firefly reloaded kernel as this is also supported by rockchip kernel in https://github.com/rockchip-linux/kernel/tree/release-4.4and https://github.com/rockchip-linux/build

Guys,

first of all thanks a lot to mac-l1 for his great job!!

I am trying to load the bin file onto my rk3288 Firefly but I got thi message:

# ./flash.sh
+ ./rkdeveloptool db rk3288_ubootloader_v1.01.06.bin
The  Device did not support this operation!

The device seems to be fine when I test it:

# ./rkdeveloptool td
Test Device OK.

Do you have hints?

Thanks!

Ok,

I had issues with bootloader and had to go to maskrom mode.

All works now!

Hello, guys! Thank you for your work.
I have an issue with thermal module in kernel. I used to successfully build opencv 2.4.9 on Firefly-RK3288 with Ubuntu 14.04 server firmware (slightly altered, I've installed X server and OpenBox there) with no issues on all 4 cores (make -j4).
However, with this firmware installed I got my Firefly automatically switched off with following message:

1. Message from syslogd@localhost at Jul  6 14:56:19 ...
   
2. kernel:[ 3690.721460] thermal thermal_zone0: critical temperature reached(90 C),shutting down
   
3. Connection to 192.168.0.109 closed by remote host.
   
4. Connection to 192.168.0.109 closed.

Copy the code

How can I disable this feature or make temperature limit higher? As I mentioned earlier, I've successfully built this version of opencv on all cores, but now kernel is more aware of current CPU temperature. Thanks.

Also I have an issue with taking backup of device partitions. Android Tool on Windows 8 show me, that my device is in Maskrom mode.

This strange behavior started to happen after I've downloaded rk3288_ubootloader_v1.01.06.bin bootloader. Could you please help with backing up procedure?

Can you please provide exact working device tree which has HDMI sound output for Reload that we can use on normal  RK3288-Firefly?

GIT link or patch,...

Thanks

+1 for git link.
I've tried this: https://github.com/rockchip-linux/kernel/tree/release-4.4 (it's 4.4.71 when mac-l1's distro is based on 4.4.55) with extracted configuration from /proc/config.gz, now I have eDP-1 presented in xrandr. If I switch eDP-1 off (e.g. xrandr --output eDP-1 --off or by passing kernel parameter video=eDP-1:d), then image shows normally.
I'm also interested in building fast booting system for embedded development, so it would be nice to have building instructions.

hi all,
I am also using https://github.com/rockchip-linux/kernel/tree/release-4.4 for my kernel which at the moment is 4.4.77.
But the HDMI output is not available as I believe is not implemented in device three.

Do you guys can get the audio on HDMI when using mac-l1 KODI packages?
I only have option for SPDIF output and there is no sound on HDMI!
I appreciate any assistance....

Hello sghazagh. How do you build a kernel?
I use instructions from here http://rockchip.wikidot.com/linux-user-guide to build linux kernel and uboot. There is also device tree generated at build time. Make sure you are using latest source code from rockchip-linux.
Also, what is the problem with HDMI output? Despite having extra output eDP-1, image is pretty stable. You can switch eDP-1 off either with

xrand --display :0 --output eDP-1 --off

or by appending parameter

video=eDP-1:d

to kernel boot arguments.

Hi mac-I1,
i've found solution. to install libudev for i386 can make it work.

sudo apt-get install libudev-dev:i386
