DG's Hardware board

Posted: **11 Jun 2015, 18:33**

Bought a new computer

Got some trouble getting it working with already owned microSD cards.

All the following mentioned MicroSD cards were formatted with the SDFormatter from https://www.sdcard.org/downloads/formatter_4/
With the options: 'OverWrite ERASE' and "FORMAT SIZE ADJUSTMENT" to "ON".

--
Raspberry default NOOBS install won't work on:

MicroSDHC 32GB Class 10 (whitelabel?, it never boots from several of these same cards, i tried 3).
And they all (3) work fine in prof video equipment, simple cam gadget or phones.
---------------------------

The only MicroSDHC card which DOES work:
Kodak MicroSDHC 4GB Class 4.
---------------------------

(It looks a 1GB card, but thats optical, it's a 4GB card, missing part of the '4'.)
But this has only 200MB free after complete Rasbian setup.

PNY MicroSDHC 32GB Class 10
---------------------------

It will boot, but failes to install.
On RPi2:

- Clearing existing EBR
- Raspbian: Creating partition entry

Followed by:

Found out that reformatting the card with the mentioned SDFormatter, does NOT work correctly within Windows XP, as after this the card seems still NOT formatted? And needs a Windows XP format before files can be copied to the card.

Bought this card especially for the Raspberry for 20 euro's and still not working?
This cost me more on SD cards then the Raspberry itself?

Tried once again, but getting other error messages:

Used a working SD-adapter and other cardreader, still same messages came up, even the writing of the card goes during 'Clearing existing EBR'?

Next used the HP-SD formatting tool, which (in my opinion) does a cleaner format as the setup went 1 time succesfully, however the 1st reboot showed too much errors and files not found, it did not boot at all.

Tried a (non quick) format with the HP tool and start all over again ...

All different tries result in different error messages like: Not able to write to FAT, or reserved sector, mounting errors, etc.

Anyway: I did mention to fix all of these errors!

Used a special program (RMPREPUSB v2.1.722) to remove the MBR from the card. (http://www.rmprepusb.com/tutorials/raspberry-pi-rpi)
Quick format the card and write noobs files to the card.
Next insert de card into RPi2 and start it up.
Raspberry tells it does not see a MBR and asks to write one. Do so!
It creates new MBR and ask to re-copy the noobs files to the card.
Power off RPi2, take card out and copy the noobs files (again) to the card and boot RPi2 again with that card.
Now it does not fail anywhere! (although copying goes slow, but could be card-manufacture related)

So it looks like the (most) issues with microSD cards are MBR related!
Windows XP and the desired format program SDFormatter does not (re)set the MBR the right way!
Remove MBR from microSD card, insert it in RPi2 and let it (re)write new MBR fix this.

As the above process only worked 'some' times, it looks alot like NOOBS does NOT correctly (re)format any microSD card!

Even when i remove the MBR (i.e. FAT table), NOOBS does recognize that and rewrites a new FAT, but even then all OS'es installed by NOOBS do NOT work.
Maybe they do work, but try a reboot or power down and up again, most OS'es (Raspbian & OpenELEC) will crash on mounting issues.

I've seen this on PNY 32GB Class10, Samsung 16GB Class10 (HC1), or unlabeled 32GB Class10 cards.
Best way to boot RPi2, take a good .img file of any OS and write them with RMPrepUSB, 'File to Drive' option.

It won't give you the NOOBS multiboot functionality, but this works best!

Only use GOOD microSD cards...
Found out that some 'cheap' ones only writes about 2.9GB but says 32GB

'What else ...' for about $5

RPI with Raspbian 4.1.13 + LCD 3.5inch with touch (WaveShare Spotpear)

After reading a lot about getting my 3.5inch LCD working on my RPi2 (again, as my older HDD crashed during it's last backup, pitty a bit).
I've found a way without installing additional driver firmware, as most is already in kernel 4.1.13
Just some linear libraries I've installed to get all working nicely.

Also a minor physical 'error' could occure.
If there is too much space between LCD screen & PCB (should be glued?)
I just pressed around, but not too hard, you could break the glass!
PCB & LCD looked 'sitting' better, as i already checked the flat-cable connection several times before.

Used:
- Raspberry Pi 2 Model B (Seen above), with latest Raspbian image (4.1.13) from http://www.raspberrypi.org
- 3.5inch LCD WaveShare Spotpear

Adjusting the code:

Added:

Code: Select all

fbcon=map:1 fbcon=font:ProFont6x11 logo.nologo fbtft_device.custom fbtft_device.name=flexfb fbtft_device.gpios=dc:24,reset:25 fbtft_device.bgr=1 fbtft_device.speed=16000000

to /boot/cmdline.txt

..

Last part of /boot/config.txt is now:

Code: Select all

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
dtparam=spi=on
dtparam=i2c_arm=on

# DG added:
device_tree=bcm2709-rpi-2-b.dtb
device_tree_param=i2s=on
dtoverlay=ads7846,speed=500000,penirq=17,speed=500000,swapxy=1
device_tree_overlay=piscreen,fbtft_device.debug=3,speed=16000000,rotate=90

And screen activate normally during next boot

(If not, some other parameters should be tested / checked, for example flexfb instead of piscreen )

To get 'startx' on LCD, only change 'fb0' to 'fb1' in the file: /usr/share/X11/xorg.conf.d/99-fbturbo.conf

Rotate screen
Change in /boot/config.txt:
device_tree_overlay=piscreen,fbtft_device.debug=3,speed=16000000,rotate=90
to
device_tree_overlay=piscreen,fbtft_device.debug=3,speed=16000000,rotate=270

Rotate touch functionality
Now only to swap left right on touch ...

Installed libts-bin (sudo apt-get install libts-bin)

Every time to use ts_calibrate, use first next 2 lines before use on CLI:

Code: Select all

export TSLIB_TSDEVICE=/dev/input/event0
export TSLIB_FBDEVICE=/dev/fb1

NOTE: event0 could be also event1 or event2

This works, adding

Code: Select all

Section "InputClass"
        Identifier      "evdev touchscreen catchall"
        MatchIsTouchscreen "on"
        MatchDevicePath "/dev/input/event*"
        Driver          "evdev
        Option          "InvertY" "true"
        Option          "InvertX" "true"
        Option          "GrabDevice" "True"
EndSection

to file: /usr/share/X11/xorg.conf.d/99-fbturbo.conf

Even better adjustment ( & added Option “InvertX” “true”, above), add following to end of same file:

Code: Select all

Section "InputClass"
        Identifier      "calibration"
        MatchProduct    "ADS7846 Touchscreen"
        Option          "Calibration" "3900 240 240 3900"
EndSection

Alignment doesn't not work nicely on 3.18.13 WaveShave LCD.
Have to investigate further (touxh xy is ok after reboot though)

!!!!

To test:

Can we combine last 2 sections of /usr/share/X11/xorg.conf.d/99-fbturbo.conf
Ie. 2 Identifiers in 1 InputClass?

!!!!

Getting the (cheap & already 1 year old) wlan usb adapter working on the RPi was more easy.

Took about 1 hour reading and testing and got it working on Raspbian 4.1.13

At least you need to install (some) mt760x drivers...

On the standard Rasbian 4.1.13 it runs quit easily as the used HW drivers are already there.
The WaveShare 3.18.13 version was some more trouble due to Linux version levels, but found a site with most versions available. (2nd on the list below) The link goes directly to page 14 on with in the first article there is a link to version 3.18.13-784, which i used.

Now this is funny ...

I've bought -last year- 3 small photo / video-camera's from ebay @ such a low prize i even cant get their real names, but i can get their brand code.

However, there's 1 button on those camera's (and a MicroSD slot with 32GB) to turn them on, 1 press on button is a photo, 1 'long' press should start video (and audio?) recording.
So far so good! First i used 32GB 'very el cheapo' MicroSD's from ebay, they only hold around 4GB and not very stable tho...
Anyway i want 2 or 3 of those cams as USBcam, and i plugged 1 into my raspberry 2B, and see with 'lsusb':
--
Bus 001 Device 005: ID 1b3f:0c52 Generalplus Technology Inc. 808 Camera #9 (mass storage mode)
--

Hmm, that is not what i want ... Oh, wait their's a button on those small things, let's press it!
And next 'lsusb' command shows:
--
Bus 001 Device 006: ID 1b3f:2002 Generalplus Technology Inc. 808 Camera #9 (web-cam mode)
--

Hahaha, found it!
But wait, whats that? Another manuafactor?

Explains alot ...
We go on

What the idea is:

Code: Select all

HOME                                           CAR
Zoneminder with several cams                   Raspberry with 1 or several cams

Pass CAR data to HOME (ZoneMinder) data, when CAR is in Wifi range and engine shuts down.

I already have ZoneMinder running locally @ home, with several cams.
Now the raspberry is in my car and, let's persume, i'm driving outside my Wifi range (most probably

)
The raspberry collects 2 (or more) USB (or direct) connected cams.
This data is being transferred to ZoneMinders DB, and kept their as long is needed, when i park my car within my Wifi range

ZoneMinder has alot of features to delete data after xxx days etc (as long as they are not archived).

So when i park my car, turn off the engine, raspberry stays on & checks Wifi.
When in range, it transfer its data to ZoneMinder / NAS.
After check if data is excepted & ok, raspberry clears its buffer and shuts down 4 next drive

Q's
---
- Should motion detect be enabled on a car-cam?
When drive then record.

- Should the rasbperry 'stream' data to ZoneMinder, so that ZoneMinder can do motion detection when data comes in?

- Is CAR data only long streams?

- Could the raspberry stay on, functioning as Wireless WebCams (on street)?

- Can the button-press (to make the cam a usbcam) be overruled?

So far so good,
Only with 2 same camera's it does work -ASCII video- with putty & mplayer command,
But on 3.5LCD with SMplayer only /dev/video0 is shown, also when using /dev/video1.

Logs from putty working session:

From within a putty session, use the following:

Code: Select all

DISPLAY=:0 mplayer tv:// -tv driver=v4l2:device=/dev/video0

Then the right video output is sent to the 3.5LCD

For even video0 as well as video1, wonder why this does not work within SMplayer GUI.
