Release Notes for the QNX Neutrino 6.4.0 BSP for Freescale MPC8313E RDB 1.0.0#System requirements#Target system#
Host development system#
System layout#The table below depicts the memory layout for the image and for the flash. Memory layout
Getting Started#Step 1: Connect your hardware#Connect the serial cable to the first serial port of the MPC8313E RDB board to the first serial port of your host machine (e.g. ser1 on a Neutrino host).
Step 2: Build 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.Step 3: Transfer the OS image to the target using the ROM monitor#On your host machine, start your favorite terminal program with these settings:
Step 4: Setting up the environment#
Step 4A: TFTP download#This method requires a raw image, which the buildfile creates by default. On your target, type the following, filling in the appropriate IP addresses and ifs file: => setenv ethact TSEC1 => setenv ipaddr 172.18.80.142 => setenv serverip 172.18.80.174 => setenv bootfile ifs-mpc8313rdb.raw => setenv loadaddr 0x200000 => setenv bootcmd 'tftpboot $loadaddr $bootfile; go $loadaddr' => setenv bootdelay 2 => saveenv Saving Environment to Flash...

Welcome to QNX Neutrino 6.4.0 on the Freescale MPC8313E RDB board Step 4B: Serial download#This method requires an SREC image. You have to modify the buildfile to create this format. Change this: [virtual=ppcbe,raw] to this: [virtual=ppcbe,srec] Rebuild the image. On your target, type: =>: setenv loads_echo 0 =>: saveenv =>: loads On your host, copy the image to the serial port that's connected to the board. For example, on a Neutrino host: cp ifs-mpc8572ds.srec /dev/ser1
Note:
The serial line shouldn't already be in use. At this point, you should see the ROM monitor download the boot image, indicated by a series of dots. You'll also see output similar to this when it finishes downloading: ## First Load Addr = 0x00200000 ## Last Load Addr = 0x0023955B -------- ? ## Total Size = 0x0013955C = 1283420 Bytes -----? ## Start Addr = 0x00101E38 -----? =>: Type: go start_addr You should now see the QNX Neutrino welcome message on your terminal screen: System page at phys:0000c000 user:0000c000 kern:0000c000 Starting next program at v00133af4 Welcome to QNX Neutrino 6.4.0 on the Freescale MPC8313E RDB board # 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. For sample command lines, please see the " Driver Command Summary" section. Creating a flash partition#
fs-etfs-mpc8313erdb512 -D cs=1
etfsctl -d /dev/etfs2 -s
etfsctl -d /dev/etfs2 -f
etfsctl -d /dev/etfs2 -c
Driver Command Summary#The driver command lines below are specific to the Freescale MPC8572DS board. See the online docs for each driver for additional command-line options and other details. NOTE: Some of these 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.
Serial#The value passed to the -c option depends on the CCB clock frequency as displayed by U-Boot at boot time, which may change depending upon board dip switch settings. For instance, CCB:166Mhz translates to -c166000000. Network:#
I2C:#Run both I2C channels: i2c-mpc5200 -p0xe0003000 -i14 --u1
Note:
For more information about these commands, see the Neutrino Utilities Reference.
