How-To use the USB Host functionnality of Armadeus boards under Linux.
Contents
Controller
- APF9328DevFull: it is equipped with a USB 2.0 Host controller (ISP1761) featuring three USB high speed ports. The ISP1761 driver is already configured with armadeus version 3. For older versions refer to the how to install USB Host Linux driver for the DevFull page
- APF27 and APF27Dev: two Host ports are available. The controllers are integrated in the i.MX27 processor. Nothing has to be done to configure the controller. No special operation has to be done to use both USB ports (driver is included in default kernel).
- APF27 PPS: one Host port and one OTG port (that can be forced to Host mode). Default Linux kernel has all the needed drivers compiled in.
- APF51Dev: 2 Host ports and one OTG port (that can be forced to Host mode). Default Linux kernel has all the needed drivers compiled in.
- PPS51 one Host port and one OTG port (that can be forced to Host mode). Default Linux kernel has all the needed drivers compiled in.
- APF28Dev: one Host port and one OTG port (Host/slave mode automatically switched depending on cable). Default Linux kernel has all the needed drivers compiled in.
Forcing an OTG port to Host mode (APF27 / APF51 / APF28)
- If you don't have an OTG compatible cable or an old APFDev board (ex: APF28Dev Rev 1), it might be needed to force Host mode on OTG port:
BIOS> setenv extrabootargs ${extrabootargs} otg_mode=host
BIOS> saveenv
BIOS> boot
Using USB devices
USB keyboard/mouse (HID: Human Interface Device)
Driver installation
- Done by default in recent releases
Plug the keyboard
- you should see on console (here on APF9328 for example):
usb 1-1.1: new low speed USB device using isp1761 and address 3 usb 1-1.1: configuration #1 chosen from 1 choice input: NOVATEK USB Keyboard as /class/input/input0 input: USB HID v1.10 Keyboard [NOVATEK USB Keyboard] on usb-platform-1.1 input: NOVATEK USB Keyboard as /class/input/input1 input: USB HID v1.10 Mouse [NOVATEK USB Keyboard] on usb-platform-1.1
- To change keyboard keymap (by default US one is used):
# loadkmap < /etc/i18n/fr.kmap
Plug the mouse
- you should see on console (here on APF9328 for example):
usb 1-1.2: new low speed USB device using isp1761 and address 6 usb 1-1.2: configuration #1 chosen from 1 choice input: Logitech USB-PS/2 Optical Mouse as /class/input/input6 input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-platform-1.2
USB Flash memory / USB key / USB card reader / USB Hard Drive
Driver installation
- Done by default in recent releases.
Plug the storage device
- You should see (for example):
usb 1-1.2: new high speed USB device using isp1761 and address 6 usb 1-1.2: configuration #1 chosen from 1 choice scsi0 : SCSI emulation for USB Mass Storage devices usb 1-1.2: reset high speed USB device using isp1761 and address 6 scsi 0:0:0:0: Direct-Access Hama Card Reader CF 1.9C PQ: 0 ANSI: 0 CCS sd 0:0:0:0: [sda] Attached SCSI removable disk
Additional configuration
- If /dev/sdaX does not exist, then create it:
# mknod /dev/sda b 8 0 # mknod /dev/sda1 b 8 1 # mknod /dev/sda2 b 8 2
- Create a mount directory "usbdisk"
# mkdir -m 777 /mnt/usbdisk
Mount the device
- Mount the USB Mass Storage device
# mount -t vfat /dev/sda1 /mnt/usbdisk
- Check what is present on the USB Mass Storage device:
# ls -al /mnt/usbdisk
- And if it is well mounted (for example):
# mount rootfs on / type rootfs (rw) /dev/root on / type jffs2 (rw) proc on /proc type proc (rw) devpts on /dev/pts type devpts (rw) tmpfs on /tmp type tmpfs (rw) sysfs on /sys type sysfs (rw) /dev/sda1 on /mnt/usbdisk type msdos (rw,fmask=0022,dmask=0022,codepage=cp437)

USB <--> WiFi adapters
U-Boot usage
USB storage can also be used with U-Boot. The following commands are useful:
- start/restart the USB:
BIOS> usb start
- show available USB devices:
BIOS> usb info
- list the USB key content (mass storage only):
BIOS> fatls usb 0
- load the file xxx.bin in RAM:
BIOS> fatload usb 0 ${loadaddr} xxx.bin
Links
- Any links ?
