Kernel kompilieren

Die Infos kommen von [eLinux]. Dort ggf. nach Neuigkeiten suchen.

Das Zielverzeichnis braucht im Moment 6.1 GB. Dauer der Builds (ohne git Downloads):

• auf job1:/data3/rpi ca. 9 Minuten
• auf job4:/dev/shm/rpi ca. 5 Minuten
• auf dem Raspberry Pi ca 22 Stunden! Nicht selbst getestet ;)

export RPI_DIR=/data3/rpi
mkdir -p "$RPI_DIR"
cd "$RPI_DIR"

Serielle Konsole anschließen

Adafruit USB Seriell Konverter Kabel anschließen:

• Rot = 5V = GPIO Pin in der Platinenecke (nur wenn Strom nicht schon über USB Port kommt!)
• Schwarz = GND = übernächster Pin
• Weiß = TXD 3,3V = nächster Pin
• Grün = RXD 3,3V = nächster Pin

Siehe auch [Adafruits Lesson 5]

Auf Linux Seite dann USB einstecken und Terminalprogramm starten (x=0,1, ...)

minicom -b 115200 -o -D /dev/ttyUSBx

oder

screen /dev/ttyUSBx 115200

Format SD Card with Standard Linux Tools

• Edit first line to match sd device name (find that with "sudo dmesg | o")
• Edit second line to match your downloaded noobs zip image
