Installing Atmel SAM-BA Utility
This topic describes how to restore memory by using the Atmel SAM-BA utility, connecting with the hardware,
mounting the serial driver and restoring the bootstrap memory or u-boot memory.
1. If you have not already done so, download the Atmel SAM-BA utility and unzip the utility package onto
your Linux development system: http://www.atmel.com/tools/ATMELSAM-BAIN-
SYSTEMPROGRAMMER.aspx
2. Connect the USB cable between Linux system and the MTEOCG hardware.
3. Mount the USB CDC serial driver as described in the topic for the Ubuntu operating system you are using.
Mounting USB CDC serial driver for Ubuntu version 9.10 and older
1. Log in with administrator rights.
2. If the usbserial and cdc_acm module is already running, unload it by using the following command:
# rmmod cdc_acm
# rmmod usbserial
3. To load the usbserial kernel module, type:
1 #modprobe usbserial vendor=0x03eb product=0x6124
4. To verify that the USB connection is established, type:
#lsusb -d 03eb:6124
5. To determine which USB connection is established, type:
#dmesg
...
kernel: usb 4-2: new full speed USB device using uhci_hcd and address 5
kernel: usb 4-
2: configuration #1 chosen from 1 choice kernel: usbserial_generic 4-
2:1.0: generic converter detected
kernel: usbserial_generic: probe of 4-2:1.0 failed with error -5
kernel: usbserial_generic 4-2:1.1: generic converter detected
kernel: usb 4-2: generic converter now attached to ttyUSBx
6. To connect to your board, use /dev/ttyUSBx .
Mounting USB CDC serial driver for Ubuntu 10.04 and newer with updated kernel
1. If you are using a 64-bit system, type the following to ensure 32-bit libraries are installed:
sudo apt-get install ia32-libs
2. To ensure that the abstract control model (ACM) device was detected and to check the port name:
#dmesg
...
kernel: usb 4-
1: new full speed USB device using ohci_hcd and address 2
kernel: usb 4-1: configuration #1 chosen from 1 choice
kernel: cdc_acm 4-
1:1.0: This device cannot do calls on its own. It is not a modem.
kernel: cdc_acm 4-1:1.0: ttyACM0: USB ACM device
kernel: usbcore: registered new interface driver cdc_acm
