Getting Started#

Starting Neutrino#

Step 1: Build the BSP
You can build a BSP OS image from the source code. For instructions about building a BSP OS image, please refer to the chapter Working with a BSP in the Building Embedded Systems manual.

• When compiling using the command line, the ifs image is in the images directory.
• When compiling using the IDE, the IFS image is by default at /Workspace_root_dir/bsp-freescale-mx53evk-src/images.

Step 2: Connect your hardware

1. Set up the i.mx53 EVK board in boot mode. Refer to the manual for the correct default jumper settings to use the CPU board.
2. Connect one end of the serial cable to the P5A1 (UART) serial port on the CPU board.
3. Connect the other end of the serial cable to the first available serial port of your host machine (e.g. ser1 on a Neutrino host).

On your host machine, start your favorite terminal program with these settings:

• Baud: 115200
• Bits: 8
• Stop bits: 1
• Parity: none

Then, apply power to the target. You should see output similar to the following:

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:

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.

Known Issues for This BSP#

• Support for most features is either limited or disabled at this time. These limited features include:
  • SD card support
  • I2C
  • SPI
  • WDT
  • USB support
  • Audio
  • Video
  • DMA
• To be determined if these issues remain
  • The audio driver deva-ctrl-mx-mx51evk.so doesn't support Syncronous data playback ability since the DMA library doesn't have position information. (Ref# 75488)
  • The i.MX35 (ARM1136) processor doesn't support unaligned accesses in hardware. If an application (e.g. pwmopts) tries to access data that isn't aligned on a 32-bit boundary, a bus error will occur. To avoid this memory fault, you can enable the software emulation of unaligned accesses by starting procnto with the -ae option. (Ref# 71252)
