4 Flashing of XM112 via USB-UART Interface
This section describes how to update the software in the HP Module by using the USB-UART
interface on XB112.
4.1
Updating the Software
4.1.1
Install Tools
In order to update the software on the HP Module it is recommended to use the BOSSA application.
The application along with instructions are available at
http://www.shumatech.com/web/products/bossa. The application is available for Linux, Windows and
Apple Mac OS X and version 1.9 or later is supported.
4.1.2
Upgrade Procedure
Step 1: The SAM E70 CPU have a ROM boot loader that is used during the software update. In order
to enter this boot mode the internal flash must be erased with the following sequence:
1. Connect the XB112 together with XM112 to your PC with a micro USB cable to the
"USB1/Power/UART0" connector
2. Press and hold the "ERASE" button on the XB112.
3. Press the "NRST" button on XB112 (still holding the "ERASE" button)
4. Release the "NRST" button
5. Release the "ERASE" button
The internal flash of the SAM E70 is now erased and the ROM boot code is executing.
Step 2: Start the BOSSA application.
IT IS VERY IMPORTANT TO NOT START THE BOSSA APPLICATION UNTIL THE
INTERNAL FLASH OF SAM E70 HAS BEEN ERASED.
1. Select correct port, e.g. "/dev/ttyUSB0" if running on Linux or "COM6" if running on
Windows. If the BOSSA application doesn't find the SAME70 on XM112, try closing
BOSSA, then redo Step 1 and Step 2.
2. Press "Browse" and select the new firmware file
3. Make sure that "Erase all" and "Boot to flash" is selected
4. Press "Write"
