Howto configure the Linux kernel / arch / cris / arch-v10 / drivers



  • Option: ETRAX_ETHERNET
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Ethernet support
    • depends on ETRAX_ARCH_V10
    • select NET_ETHERNET
      This option enables the ETRAX 100LX built-in 10/100Mbit Ethernet controller.


"Network LED behavior"

    • depends on ETRAX_ETHERNET
    • default ETRAX_NETWORK_LED_ON_WHEN_ACTIVITY


  • Option: ETRAX_NETWORK_LED_ON_WHEN_LINK
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) LED_on_when_link
      Selecting LED_on_when_link will light the LED when there is a connection and will flash off when there is activity.
      Selecting LED_on_when_activity will light the LED only when there is activity.
      This setting will also affect the behaviour of other activity LEDs e.g. Bluetooth.


  • Option: ETRAX_NETWORK_LED_ON_WHEN_ACTIVITY
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) LED_on_when_activity
      Selecting LED_on_when_link will light the LED when there is a connection and will flash off when there is activity.
      Selecting LED_on_when_activity will light the LED only when there is activity.
      This setting will also affect the behaviour of other activity LEDs e.g. Bluetooth.



  • Option: ETRAX_SERIAL

    • (on/off) Serial-port support
    • depends on ETRAX_ARCH_V10
      Enables the ETRAX 100 serial driver for ser0 (ttyS0) You probably want this enabled.

    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Use fast timers for serial DMA flush (experimental)
    • depends on ETRAX_SERIAL
      Select this to have the serial DMAs flushed at a higher rate than normally, possible by using the fast timer API, the timeout is approx. 4 character times. If unsure, say N.


  • Option: ETRAX_SERIAL_FLUSH_DMA_FAST
    • Kernel Versions: 2.6.15.6 ...
    • (on/off) Fast serial port DMA flush
    • depends on ETRAX_SERIAL && !ETRAX_SERIAL_FAST_TIMER
      Select this to have the serial DMAs flushed at a higher rate than normally possible through a fast timer interrupt (currently at 15360 Hz). If unsure, say N.

    • default "5"
      Number of timer ticks between flush of receive fifo (1 tick = 10ms). Try 0-3 for low latency applications. Approx 5 for high load applications (e.g. PPP). Maybe this should be more adaptive some day...

    • (on/off) Real Time Clock support
    • depends on ETRAX_ARCH_V10
      Enables drivers for the Real-Time Clock battery-backed chips on some products.
