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/mx51evk/build Getting Started#Preparing an SD Card#The i.MX51 EVK can boot from USB, UART, SPI-NOR, MMC-1 (on bottom side of board), or MMC-2 (on top side of board). For example, to boot from the bottom SD slot, set dipswitch SW1 like to 0-0-0-0-0-0-1-1-0-0, see i.MX51 EVK board documentation for more boot switch details. An SD card can be configured to by dd'ing the redboot image to the beginning of the SD card: dd if=mx51_babbage_redboot.bin of=/dev/sdX 'dmesg' can be used on a Linux host to determine the SD device - e.g. /dev/sdd. The redboot image can be downloaded at the same Foundry27 location where the QNX BSP was downloaded. 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: ++Booting from SDHC0 Bus Width: 1 Card initialization successful!

Auto Display Detection#The i.MX51 EVM supports multiple output displays. This BSP's default build file produces an IFS that will auto detect which display is connected and configure video output for that display. The BSP checks for attached displays in the following order: WVGA LCD Display Panel VGA is the default and is selected if neither the LCD nor the DVI-D monitor are detected. Note that if both the DVI-D and LCD panel are attached, the display will be configured for the LCD. Also, to detect a DVI-D monitor it must be connected to the DVI connector on the i.MX51 EVM and the monitor must be turned on. 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, Ethernet, and Graphics have additional details: Startup#startup-mx51evk [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.
Note that both -d1 and -d2 must be specified to support auto display detection using the display-detect program. Ethernet#io-pkt-v4-hc -d mx51 mac=xxxxxxxxxxxx MAC address labelled on i.mx51 evk board must be provided with "mac" command line option. Audio#io-audio -d mx-mx51evk ssibase=0x83FCC000,tevt=29,tchn=1,revt=28,rchn=2,rate=48000,mixer=i2cdev=1:adr0cs=0:mclk=26000000 mix_ctl group "Mic In" capture=on
Note:
1.To start the audio system, you'll need to execute the I2C driver "i2c-mx35 --u1,1" first. 2.This audio driver sets "Line in " as the capture default device. i.MX51 EVK uses "Mic in " capture device.Please run "mix_ctl group "Mic In" capture=on" to set the capture device after the audio driver running. Graphics#PATH=/proc/boot:/sbin:/bin:/usr/sbin:/usr/bin display-detect io-display -dvid=0,did=0,deviceindex=# The display-detect program uses the i.MX51 EVM display hardware to detect the attached display and then replaces the '#' in the io-display command line with the selected displayindex using the following mapping:
The display.conf config file then maps these indexes 0-2 to driver config files imx51.conf, imx51-1.conf, and imx51-2.conf respectively to get the appropriate output display timing and configuration settings. Accelerated Graphics#An archive containing an experimental driver for the GPU (OpenVG & OpenGLES) can be found on the Foundry 27 graphics project: http://community.qnx.com/sf/go/projects.graphics/frs.imx51_gpu_driver Please obtain the latest version and follow the corresponding setup instructions.
