Host development system
System Layout#The tables below depict the memory layout for the image.Memory layout
The interrupt vector table can be found in the buildfile located at src/hardware/startup/boards/mx51pdk/build
Getting Started#Starting Neutrino#Step 1: Build the BSP Copy or transfer the IFS image into your tftp server's directory.
Step 2: Connect your hardware
On your host machine, start your favorite terminal program with these settings:
Then, apply power to the target. You should see output similar to the following:

Step 3: Setup the environment At the RedBoot prompt, issue the fconfig command to change the current environment. The current configurations will be displayed; change the configuration if you want. Run script at boot: false Use BOOTP for network configuration: false Gateway IP address: 192.168.1.1 Local IP address: 192.168.1.202 Local IP address mask: 255.255.255.0 Default server IP address: 192.168.1.15 Board specifics: 0 Console baud rate: 115200 Set eth0 network hardware address [MAC]: false Set FEC network hardware address [MAC]: false GDB connection port: 9000 Force console for special debug messages: false Network debug at boot time: false Default network device: mxc_fec Step 4: Boot the IFS image Once the above setup is complete, reset the board and you can run the load command at the RedBoot prompt to download the image: load -v -r ifs-mx51pdk.raw -m tftp -b 0x90100000 Replace 192.168.1.15 with the IP address of your TFTP server and ifs-mx51pdk.raw with the path of the image on the TFTP server. RedBoot will display the follow message and start downloading the boot image: Using default protocol (TFTP) If the image is successfully loaded RedBoot will display: Raw file loaded 0x90100000-0x9030db4f, assumed entry at 0x90100000 Type go 0x90100000 to jump to startup and boot the IFS image. You should see QNX Neutrino boot, followed by the welcome message on your terminal screen: CPU0: L1 Icache: 512x64 CPU0: L1 Dcache: 512x64 WB CPU0: L2 Dcache: 4096x64 WB CPU0: VFP 410330c2 CPU0: 412fc085: Cortex A8 rev 5 800MHz System page at phys:90011000 user:fc404000 kern:fc404000 Starting next program at vfe040e74 cpu_startnext: cpu0 -> fe040e74 VFPv3: fpsid=410330c2 coproc_attach(10): replacing fe062c84 with fe062444 coproc_attach(11): replacing fe062c84 with fe062444 Welcome to QNX Neutrino trunk on the i.MX51PDK (ARM Cortex-A8 core) Board Starting I2C1 driver... Starting I2C2 driver... Starting watchdog Starting USB Host driver... starting Input Drivers... # You can test the OS simply by executing any shell builtin command or any command residing within the OS image (e.g. ls). Driver Command Summary#The following table summarizes the commands to launch the various drivers.
Some of the drivers are commented out in the default buildfile. To use the drivers in the target hardware, you'll need to uncomment them in your buildfile, rebuild the image, and load the image into the board. Startup, Watchdog, Configurable SPI, Enhanced Configurable SPI and Ethernet have additional details: Startup#startup-mx51pdk [startup-options] Some modules aren't enabled after boot up, so you need to use command line options to startup to enable them. These options must be passed before any other startup options.
CSPI and Enhanced CSPI#spi-master -d mx51cspi base=0x83FC0000,irq=38,waitstate=2,loopback=1 spi-master -d mx51ecspi base=0x70010000,irq=36,waitstate=2,loopback=1 Note: There is no peripheral available on CSPI interface and Second Enhanced CSPI Interface on the i.mx51 EVK board. Ethernet#io-pkt-v4-hc -d mx51 mac=xxxxxxxxxxxx syspage MAC address labelled on i.mx51 evk board must be provided with "mac" command line option.
