Getting Started#Starting Neutrino#Step 1: Build the BSP
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: U-Boot 2009.08 (Mar 29 2010 - 04:22:30) CPU: Freescale i.MX53 family 1.0V at 800 MHz mx53 pll1: 800MHz mx53 pll2: 600MHz mx53 pll3: 216MHz ipg clock : 60000000Hz ipg per clock : 50000000Hz uart clock : 21600000Hz cspi clock : 54000000Hz ahb clock : 120000000Hz axi_a clock : 300000000Hz axi_b clock : 200000000Hz emi_slow clock: 200000000Hz ddr clock : 300000000Hz esdhc1 clock : 120000000Hz esdhc2 clock : 120000000Hz esdhc3 clock : 120000000Hz esdhc4 clock : 120000000Hz Board: MX53 EVK 1.0 [POR] Boot Device: SD I2C:In: serial Out: serial Err: serial Net: FEC0 [PRIME] Hit any key to stop autoboot: Step 3: Boot the IFS image SD card download#Copy the raw OS image ifs-mx53evk.raw onto a mmcsd card, then insert the SD card in the MMCSD port and apply power to the target board. After U-boot is started, boot the ifs-mx53evk.raw image in the mmcsd card as follows from the # prompt: mmcinit or mmc init (depends on which version of uboot you are using) fatload mmc 0 0x90100000 ifs-mx53evk.raw go 0x90100000 If the image is successfully loaded U-Boot will display: ## Starting application at 0x90100000 You also 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 fec_disable init_hwinfo mx51_init_i2c mx51_aud_mux_init mx51pdk_fec_init mx51_usb_host_init mc51_init_esdhcv2 mx51_cspi_mux_init init_audio System page at phys:70011000 user:fc404000 kern:fc404000 Starting next program at vfe044e74 cpu_startnext: cpu0 -> fe044e74 VFPv3: fpsid=410330c2 coproc_attach(10): replacing fe066c84 with fe066444 coproc_attach(11): replacing fe066c84 with fe066444 Welcome to QNX Neutrino 6.4.1 on the i.MX53 EVK (ARM Cortex-A8 core) Board Starting on-board ethernet with TCP/IP stack... Getting network address with DHCP... fec0: flags=843<UP,BROADCAST,RUNNING,SIMPLEX> mtu 1500 address: XX:XX:XX:XX:XX:XX media: Ethernet autoselect (100baseTX full-duplex) status: active inet xxx.xxx.xxx.xxx netmask 0xfffff000 broadcast xxx.xxx.xxx.xxx # 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-mx53evk [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.
Ethernet#io-pkt-v4-hc -d mx53 mac=xxxxxxxxxxxx MAC address labelled on i.mx53 evk board must be provided with "mac" command line option.
