Release Notes for the QNX Neutrino 6.4.0 BSP for TI OMAP-L138 EVM#

1.System Requirements#

1. QNX Neutrino RTOS 6.4.0
2. Board version: TI OMAP-L138 EVM
3. L138 processor
4. 64MB DDR SDRAM
5. 8 MB SPI flash

Host Requirements

1. QNX Momentics 6.4.0
2. Terminal emulation program (Qtalk, Momentics IDE Terminal, tip, HyperTerminal, etc.)
3. RS-232 serial port and serial cable, or a USB-to-serial cable
4. Ethernet link

2.Getting Started#

2.1 Building the BSP#

You can build a BSP OS image from the source code or the binary components contained in a BSP package. For instructions about building a BSP OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual.

2.2 Connect your Hardware#

Connect the serial cable to the serial port of the TI OMAP L138 EVM board to the serial port of your host machine. There is 1 serial port on TI OMAP L138 EVM board. Usually you should see some Uboot output on the console when you connect cable to the correct port.

The correct terminal settings of the program handling serial connection should be:

2.3 Setup you environment#

1. Power on your target. You should see the u-boot output on your console. 2. Connect an ethernet cable to the Baseboard's port.

3. Boot the IFS image#

3.1 Boot via tftp#

=> setenv ipaddr 10.90.74.214
=> setenv serverip 10.90.74.42
=> setenv bootfile ifs-omapl138.raw
=> setenv loadaddr 0xC0008000
=> setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr'
=> setenv bootdelay 2
=> saveenv
Saving Environment to SPI Flash...
Erasing SPI flash...Writing to SPI flash...done
=> boot

At this point, you should see output similar to this when it finishes downloading:

## Starting application at 0xC0008000 ...
Welcome to QNX Neutrino on a TI OMAP L138 Platform
#

Congratulations! QNX 6.4.0 kernel is running on your system. You can test the OS simply by executing any shell builtin command or any command residing within the OS image (e.g. ls). Once the initial image is running, you can update the OS image using the network and flash drivers. Still the network and flash drivers need to be supported for the TI OMAP L138 EVM board.

7. Driver Command Summary#

Network#

To start network driver without encryption, run:

io-pkt-v4-hc -dmpcsec -p tcpip-v6 ipsec -dmpc85xx mac=00112233AABB,emu_phy=0

you should see following output when you run ifconfig

# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
        inet 127.0.0.1 netmask 0xff000000
tsec0: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=0
        address: 00:11:22:33:aa:bb
        media: Ethernet none
tsec1: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=0
        address: 00:11:22:33:aa:bc
        media: Ethernet none
tsec2: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
        capabilities rx=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
        capabilities tx=0
        enabled=0
        address: 00:11:22:33:aa:bd
        media: Ethernet none

To bring a network interface up, type following command

ifconfig tsec0 10.90.74.214/24 up

Here 10.90.74.214 is the IP address assign to your target and 24 is the netmask bits (i.e. 255.255.255.0) The LEDs of the RJ45 ports corresponding to an enabled interface shall glow periodically. This can be used to identify the correct port corresponding to each tsec.
