Description
This is the Armadeus System's standard development board/baseboard for the APF6 module.
The following options are available:
Errata
- As the board is also used for APF6_SP module (APF6+FPGA), you might experience some miscellaneous FPGA LED blinking (beside "FPGA_SW" button) when no FPGA is present.

Tips
U-Boot
- Using 7" 800x480 LCD with 3.10/3.14 legacy kernel:
BIOS> setenv extrabootargs video=mxcfb0:dev=lcd,800x480@60,if=RGB666,bpp=32
then, after having booted Linux, do:
root@apf6 ~ # fbset > /etc/fb.modes
- Activating HDMI console with USB keyboard in U-Boot (since armadeus-6.0):
BIOS> usb start BIOS> setenv stdout serial,vga BIOS> setenv stderr serial,vga BIOS> setenv stdin serial,usbkbd
keyboard map is english one and it seems not possible to change it (U-Boot 2014.07) ?
- Use APF6Dev "User" LED in U-Boot scripts:
Declare GPIO Port 7 Pin 12 (connected to the LED) as GPIO:
BIOS> md.l 0x020b4004 1 020b4004: 00000100 BIOS> mw.l 0x020b4004 0x00001100 (set bit 12)
Switch LED on:
BIOS> md.l 0x020b4000 1 020b4000: 00000f04 BIOS> mw.l 0x020b4000 0x00001f04 (set bit 12)
Switch LED off:
BIOS> mw.l 0x020b4000 0x00000f04 (clear bit 12)
Linux
- to activate login in Framebuffer console, please uncomment /etc/inittab line 35 this way:
# Set up a getty on LCD tty1::respawn:/sbin/getty 38400 tty1
