Location of source and documentation

When you install BSPs, you'll find the source code in $QNX_TARGET\usr\src\archives\qnx\ on Windows, and in $QNX_TARGET/usr/src/archives/qnx/ on QNX Neutrino and Linux.

You can read the documentation (including release notes) in the Integrated Development Environment's help system on all host OSs; on self-hosted QNX Neutrino systems, you can also read it in the Photon helpviewer, or you can use a web browser to display:

${QNX_TARGET}/usr/help/product/momentics/bookset.html

This “roadmap” page contains links to the various HTML booksets that accompany the OS (e.g. System Architecture, QNX Neutrino Programmer's Guide, Library Reference, Utilities Reference, etc.).

• I2C: Inter-Integrated circuit protocol module
• SPI: Programmable serial controller
• PCI: PCI controller
• USB: EHCI USB host controller

System requirements

Target system

• Freescale ADS5121e reference board
• 64 MB flash
• U-Boot or IPL

Host development system

• Terminal emulation program (e.g. HyperTerminal, qtalk, tip, minicom, or Momentics IDE editor)
• 150 MB of free disk space
• 32 MB of RAM
• RS-232 serial port
• NULL-modem serial cable
• Ethernet link (optional, but recommended for image transfers)

Step 1: Connect your hardware

Connect the serial cable to the first serial port of the Freescale ADS5121e reference board and to the first serial port of your host machine (e.g. ser1 on a Neutrino host, /dev/ttyS* on Linux, COM1 on Windows, etc).

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

1. On your host machine, start your favorite terminal program with these settings:
   • Baud: 115200
   • Bits: 8
   • Stop bits: 1
   • Parity: none
2. Apply power to the board.
3. Configure the board for a TFTP transfer.
4. Copy the image from your host to the target using this command:

   tftpboot 0x200000 /xfer/ads5121e.raw
   go 0x200000

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

Welcome to QNX Neutrino 6.3 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).

System layout

The table below depicts the memory layout for the image and for the flash.

Item	Address
OS image loaded at:	0x80200000
OS image begins execution at:	0x80200000
NOR Flash base address	0xfc000000

You should now have a /fs0p0 directory where you can copy files to.

Fixed issues for this BSP

This version of the BSP addresses the following issues:

Known issues for this BSP

• The current NAND Flash driver works on ADS5121e Rev3.2 boards. The NAND interface was modified (significantly) for the ADS5121e Rev3.5 and Rev 4 boards. A new NAND Flash driver will be delivered in a follow-on release of the ADS5121e BSP.
• The current EIDE driver only works in PIO mode. DMA mode will be supported in a follow-on release of the ADS5121e BSP.
• There are no real audio codec connect to the I2S interface on the board. The I2S audio driver deva-ctrl-mpc5121_i2s.so was tested by loopback mode. An invalid clock rate issue is observed in the loopback mode.
• The resolution of the playback/capture positional information returned by the audio drivers deva-ctrl-mpc512x.so and deva-ctrl-mpc5121_i2s.so to the client is limited to the fragment size.
• Don't rename the directory after running setupbsp, or else you won't be able to build or uninstall the BSP properly. (QNX Ref# 38361)
• If you uninstall this BSP, the uninstaller removes only those files that were originally shipped with the BSP (whether or not you modified them). If you've added any files, they remain on your system. (QNX Ref# 38368)
• The uninstaller script doesn't remove itself when you uninstall the BSP. (QNX Ref# 38368)
• If you install a BSP more than once, and then uninstall an instance of it, the documentation for all copies of the BSP is uninstalled. (QNX Ref# 38320)
• All QNX BSPs ship with an images/Makefile whose purpose is to build an image filesystems (ifs) file using drivers built from source. Currently, it's set up to copy buildfiles from within the source directory structure (source/hardware/startup) to the images directory so that it can generate an ifs. This happens automatically when you do a top-level make, but this mechanism doesn't work when you're making an binary BSP. (QNX Ref# 38242)

  Workaround: For a binary-only BSP, change these lines in the root Makefile:

  all: install links $(if $(wildcard images/*),images)
      @echo done
    

  to the following:

  all: prebuilt links $(if $(wildcard images/*),images)
      @echo done
