I don't think you got the EXACT same LCD panel,

Are you using the correponding driver of your panel ?

Man I guess you aren't using the driver of your lcd panel...

You have to get it. Ask the vendor, or use google to get it using exact reference of your board.

To instal a driver you generally must follow the readme present in the CD.

You got to google with your exact reference + raspberry I guess you'll find the solution.

Dear Yakelkun,

I'd like to express my experiences using partly your description.
For now I had two major obstacles and put some effort in getting around these and I don't want this to be unexpressed here.

My Setup:
- Raspberry Pi 2
- Waveshare 5'' screen (using HDMI and GPIO)
- Volumio 1.55 (08/02/2016) (based on Debian Jessie!)

Code: Select all
cd /root
wget http://osoyoo.com/wp-content/uploads/samplecode/raspberry_35_inch_ts.rar
tar -zxvf  raspberry_35_inch_ts.rar
tar -zxvf LCD-show.tar.gz
(you get a ready to use raspbian distro with drivers and the drivers !!)
Code: Select all
tar xvf LCD-show.tar.gz
(the drivers)
Code: Select all
cd LCD-show
./LCD35_v1
<-- Should take several minutes before automatic reboot. DON'T EVER REBOOT when shuting down process started, the reboot last for minutes too.



I set up Volumio and installed the Screen using your description and these drivers from the waveshare page.
There I got the first error!
Kernel panic - unable to mount root fs on unknown block
RasPi didn't start up anymore.
I tried different things, googled a lot until I found out that due to the repartitioning the root partition was on mmcblk0p3 but cmdline.txt (the new one written while the drivers were installed) mentiones mmcblkop2.

SOLUTION: Put your sd card in a pc, and change the cmdline.txt in the boot partition. There is a part with root=/dev/mmcblk0p2, just change it to 3 and it should work.
I guess another solution, and the more sustainable one would be to move the root fs to partition 2 again. Will try that out later.

After that was done the next problem was at hand.
If you install startx on Debian Jessie, it will not start on this type of screen. The error: No screens found If you look into the suggested log file for more info, you will find that fbturbo could not be loaded. That is because fbturbo is just not installed in Jessie!
There are descriptions to compile fbturbo on your own (for examplehere)

After compiling fbturbo - voila - it worked. Startx started.

That's where I am now and I try to update as soon as I have more.

Thanks for your description motivating me to approach this!

Ben,

please have a look at my previous post.

You need to change the cmdline.txt in the boot partition.
