4. Software Configuration
4.1 Connecting to the AM453x
1 Insert the AM453x in an uTCA chassis or in an ATCA Carrier Board.
2 Establish a serial connection with the AM453x using the front panel serial port. The serial port
configuration: 115200 baud, 8 bits, no parity, and 1 stop bit
3 The AMC is pre-programmed with a Linux OS.
Default login:
• User Name: root
• Password:”root”
It is highly recommended to change the root password. The password can be changed by using the “passwd”
command. A new account can be created by using the “adduser” command.
4.2 Changing the Serial Console Routing
1 Boot the AMC board from the routed serial port and hit a key to break into u-boot. By default the Serial
Console is routed to the faceplate RJ45 connector.
2 Use one of the following command to configure the serial console.
• To configure the Serial Console port to work from the RTM through port 15:
U-Boot>> setenv bootargs_mtd ‘console=ttyS1,115200 mtdparts=spi0.0:1024K(boot),3072K
(kernel),28672K(rootfs) rootfstype=jffs2 root=/dev/mtdblock2 rw’
U-Boot>> run boot_spi
• To configure the Serial Console port to work from the faceplate RJ45 connector:
U-Boot>> setenv bootargs_mtd ‘console=ttyS0,115200 mtdparts=spi0.0:1024K(boot),3072K
(kernel),28672K(rootfs) rootfstype=jffs2 root=/dev/mtdblock2 rw’
U-Boot>> run boot_spi
3 To make this change permanent, type the following command:
U-Boot>> saveenv
