[Buildroot] orange-pi build not working

[Buildroot] orange-pi build not working

[paul]

Hi ,

I did pull the current 'buildroot' from git, and did a build with the 2 
configs provided for orange pi boards -
orangepi_pc_defcongfig
orangepi_one_defcongfig

Here are the results of testing for both types of builds -
1. The hdmi supports is not enabled - nothing comes on screen
2. The 'orange-pi' boards have dedicated serial port for boot logging; 
the very first boot completes successfully - through the serial port I 
am able to log-in as root, and run commands; for ex. 'uname -a' returns 
'4.9.0' kernel;
3. After first reboot, and any other boot the board reaches to the point 
of starting the kernel but does not go any further.

Here is the output from the serial port logging -
------------
	..........
Scanning mmc 0:1...

Found U-Boot script /boot.scr

reading /boot.scr

300 bytes read in 14 ms (20.5 KiB/s)

## Executing script at 43100000

reading zImage

3545792 bytes read in 189 ms (17.9 MiB/s)

reading sun8i-h3-orangepi-pc.dtb

13056 bytes read in 24 ms (531.3 KiB/s)

## Flattened Device Tree blob at 43000000

    Booting using the fdt blob at 0x43000000

    Using Device Tree in place at 43000000, end 430062ff



Starting kernel ...
----------------

Questions -
1. Why is the hdmi port not enabled?
2. Why does it boot completely only time, and then stops at 'Starting 
kernel ...' ?


Thanks,
Paul.

That is expected. There is currently no support in the mainline Linux
kernel for the HDMI output on the H3 SoC used on these boards.

So no output at all after this? It sounds like your kernel image has
somehow gotten corrupted. How did you reboot?

Does it work again if you rewrite sdcard.img to the SD card?

Hi,

Please keep the buildroot list in CC so others can help as well.

Funky, how are you powering the boards?

I do have an orangepi-pc board stacked away here, and it did work in
the past. I'll try to find time this weekend to retest.

Hi,

Sorry if this is unhelpful but have you told your kernel to use console ?

I can get the same results if  i dont set the console=... to uart in
boot argument on my imx7 board.

kind regards,
Micha?l

Hello Peter ,

Regarding -
 > Funky, how are you powering the boards?
I use a cable - usb to power jack. This way is ok for powering and 
booting with  images from the oragngepi.org - ubuntu,debian...
The vendor of the boards recommends using 5v/2a power supply.
Just to be sure it is not a powering issue I did use 5v/2a adapter but 
the result is the same - stops after starting kernel.

Let me know the results of your test with orangepi .


Thanks, Paul.

Hello Micha?l ,

raspberry-pi and may be your imx7 board has a 'cmdline.txt' file in the 
first fat partition where you specify - 'console=...' parameter.

However orange-pi does not have or use 'cmdline.txt' file in the first 
fat partition.
There are 3 files -
boot.scr, sun8i-orangepi-pc.dtb, zImage

Besides, the orange-pi completes successfully the very first boot. Does 
your imx7 board completes the very first boot without 'console=...' 
parameter?


Paul.

[Buildroot] orange-pi build not working

[paul]

Hi ,

I did find a solution to the one time boot for 'orange pi' boards.
In order to keep booting I did change through the build-root config -
- select 'linux headers' as '4.7.x'
- select 'kernel' as '4.7'

I made a build and did test - successfully booting multiple times.

Why do the builds with newer 4.8 and 4.9 kernels boot only 1 time?

I did not find the exact reason but here are some hypotheses -
- u-boot documentation (pretty old-2007) mentions 'boot-count' 
parameter, used in making u-boot, and passing it to kernel
- u-boot documentation provides a source of a kernel driver to modify 
boot count through the '/proc' ;


Paul.
