System requirements#

Target system#

Host development system#


System layout#

The tables below depict the memory layout for the image and for the flash.

ItemAddress
OS image loaded at:0x80200000
OS image begins execution at:0x80200000
NOR Flash base address0xfc000000
NAND Flash base address0x40000000


Getting Started#



Step 1: Connect your hardware#

Note:
If you have a Neutrino host with a <em>serial</em> mouse,you may have to move it to the second serial port on your host, because some terminal programs require the first serial port.

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.

Step 3: Transfer the OS image to the target#

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

2.Apply power to the board.

3.Configure the board for a TFTP transfer.

>setenv ipaddr <ipaddress>
>setenv serverip <serverip>
>setenv netmask <netmask>
>setenv bootfile ads5121e.raw
>saveenv

4.Copy the image from your host to the target using this command:

tftpboot 0x200000 
go 0x200000

You should now see the Neutrino welcome message on your terminal screen:

Welcome to QNX Neutrino 6.4.0 on the Freescale ADS5121e board

You can now test the OS simply by executing any shell builtin command or any command residing within the OS image(e.g. ls).

Creating a flash partition#



1. Enter the following command to start the flash filesystem driver:

      devf-mgt5200 -s0xfc000000,64M -r
2.To prepare the area for the partition, enter the following command: 
      flashctl -p/dev/fs0 -o7m -l50m -ve

3. Format the partition:

      flashctl -p/dev/fs0p0 -o7m -l50m -vf
4. Slay, then restart the driver: 
      slay devf-mgt5200
      devf-mgt5200 -s0xfc000000,64M -r
You should now have a /fs0p0 directory where you can copy files to.
