1 Getting Started

1.1 Connectivity

  1. Connect USB UART on the Microzed (Red PCB) to a PC - not the Micro-USB on the Powerboard (that's the JTAG Interface)
  2. Connect Ethernet
  3. Apply Power

Default account: 

user: root
password: beta

The Beta requests an IP via DHCP by default.

Over the Serial Console (USB UART) you can set the IP manually if DHCP is not an option: 

ifconfig eth0 192.168.0.9/24 up # use proper IP/prefix

1.2 Setup

Run the init script 

./kick.sh

This will initialize all systems and train the sensor communication.

1.3 Capture an image

write the image into file: snap.raw16 plus display it with imagemagick: 

ssh root@*BETA-IP* "./cmv_snap3 -e 10ms" | tee snap.raw16 | display -size 4096x3072 -depth 16 gray:-

same for 12bit (more efficient, same data): 

ssh root@*BETA-IP* "./cmv_snap3 -2 -e 10ms" | tee snap.raw12 | display -size 4096x3072 -depth 12 gray:-

1.3.1 cmv_snap3

Example: 

ssh root@cameraip "./cmv_snap3 -B0x08000000 -x -N8 -L1024 -2 -e 5ms" >/tmp/test.seq12

-B setzt die buffer base und ist im augenblick erforderlich
0x08000000 bedeutet 128MB, ich hab das linux auf 128MB zusammengepfercht, damit bleibt 1024MB-128MB fuer sequenzen
bitte beachten, es gibt kein sicherheitsnetz und keine plausibilitaetschecks, d.h. wenn du addressen erreichst oder spezifizierst wo das linux laeuft, dann ist vermutlich ein reset notwendig
-x bedeutet das erste frame zu skippen (optional), da mir aufgefallen ist, dass das erste frame nach einer pause anders aussieht
-N setzt die anzahl der frames die zu capturen sind (bitte wieder beachten, wenn du ueber 0x3FFFFFFF kommst, dann ueberschreibst du den linux bereich)
-L setzt die anzahl der zeilen (nur gerade werte, max 3072)
-2 stellt auf 12bit output (einziges format das ich getestet habe :)
-e setzt die exposure wie gehabt

To split one seq12 file into multiple individual files: 

split -b <size> <file.seq12> <prefix>

<size> ist die raw12 size ohne register
<prefix> ist der name der mit .xx verwendet wird fuer die raw12 bilder
man kann noch --additional-suffix=.raw12 drantun
dann sollten sie auch .raw12 heissen
-d oder --numeric-suffixes gibts auch, dann verwendet er fuer .xx nur ziffern
(man split fuer mehr details)

2 General Info

2.1 Operating System

At this moment we were able to reuse an Arch Linux image for the Zedboard on the Microzed. To do so, some software such as the FSBL and uboot were added. More information can be found here: http://stefan.konink.de/contrib/apertus/ I will commit myself on the production of a screencast of the entire bootstrap proces from the Xilinx software to booting the MicroZed.

I would suggest running Arch Linux on the AXIOM Beta for development purposes. If we need to shrink it down that will be quite trivial. Obviously we can take the embedded approach from there, as long as we don't fall in the trap of libc implementations with broken threading.


2.2 Userspace

Arch Linux comes with systemd, which has one advantage that the boot process is incredible fast. Standard tools such as sshd and dhcpcd have been preinstalled. We may need other tools such as ftp, webserver, etc.

  • ftp; I would suggest vsftpd here
  • webserver; I am able to modify cherokee with custom C code to directly talk to specific camera sections. Cherokee already powers the WiFi module of the GoPro.

One idea to store camera relevant parameters inside the camera and provide access from most programming languages is to use a database like http://en.wikipedia.org/wiki/Berkeley_DB
