USB Host
From ArmadeusWiki
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).
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

Driver installation
(already configured with armadeus svn version 978 or higher)
- Add USB Flash support in Linux:
$ make linux26-menuconfig
select Device Drivers ---> SCSI device support ---> <*> SCSI device support (static) select Device Drivers ---> SCSI device support ---> [*] legacy /proc/scsi/ support (static) select Device Drivers ---> SCSI device support ---> <*> SCSI disk support (static)
select Device Drivers ---> [*] USB support ---> [*] USB device filesystem (static) select Device Drivers ---> [*] USB support ---> <*> USB Mass Storage support (static)
Plug the 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)
