|
The source code requires a BSP Source License. |
Binary components
- IPL
- Startup
- Serial driver
- I2C driver
- Audio driver
- USB init utility
- USB support (included with OS)
- Graphics driver
- Link library
- DSP manager
- Network driver (included with OS)

Source code
- IPL
- Startup
- Serial driver
- Audio driver
- Graphics driver
- I2C driver
- DSP manager
- USB init utility
- Network driver
- Flash driver.
|
In order to run the audio driver, you'll need to use the DSP manager to download a DSP image to the OSK board. This DSP image is only available from Texas Instruments. The DSP image must match the Link library version 1.11 provided with this BSP. Please contact your Texas Instruments sales team to obtain it. |
|
The flash filesystem library is included in the separately available Flash Filesystem & Embedding Technology Development Kit (TDK). |
Documentation
- TI OMAP 5912 OSK BSP readme (HTML)
|
Each BSP guide contains board-specific information and instructions on building an OS image for that particular board. The procedure for building BSPs has changed since QNX Momentics 6.2.1. For instance, you must now run the . ./setenv.sh script before compiling your BSP source. If you fail to run this shell script prior to building the BSP, you can overwrite existing binaries or libs that are installed in $QNX_TARGET. For details, see the chapter "Working with a BSP" in the Building Embedded Systems manual (in the Documentation Roadmap page under the QNX Neutrino RTOS section). |

Fixed issues
The BSP documentation is up-to-date for USB and I2C. (Ref# 20756)
Known issues for this BSP
- In Microsoft Windows,
certain programs (e.g. Norton Ghost) add directories inside double
quotation marks (e.g. ...;"c:\Program Files\Norton Ghost\";...)
to your PATH environment variable.
This causes the Cygwin spawn() function to fail, which in
turn causes cp to fail when called by ln-w.
(Ref# 20046)
Workaround: Modify your PATH environment variable and remove any quotation marks.
- In those instances where the the ROM monitor's MAC address
is different from the one you pass in when running io-net,
the host can cache the ROM monitor's address. This can result in
a loss of connectivity.
Workaround: If you need to specify a MAC address to io-net, we recommend that you use the same MAC address that the ROM monitor uses. This will ensure that if the host caches the ROM monitor's MAC address, you'll still be able to communicate with the target. Otherwise you might need to delete the target's arp entry on your host.
- Simply uncommenting the io-graphics line in the buildfile
isn't enough to run Photon on the target; this line shows how to run the
graphics driver only.
For more information on embedding Photon on your board, see the Photon in Embedded
Systems appendix of the Photon Programmer's Guide.
To test or evaluate Photon on your target before embedding it you could make the Photon environment accessible to the target by simply mounting your host environment into the target. You'll need to use an NFS or CIFS client on the target depending on the type of server running on your host platform. This example shows how to create a basic Photon configuration using an NFS client.
- Uncomment the following sections from the build file: network, usb and graphics
- Add the following at the end of the network section:
fs-nfs3 10.0.0.1:$QNX_TARGET/cpu/ / 10.0.0.1:$QNX_TARGET/etc /etc 10.0.0.1:$QNX_TARGET/usr/photon /usr/photon & waitfor /usr/bin waitfor /usr/photon waitfor /etc Where 10.0.0.1 is the server IP address
The first three lines of the fs-nfs command comprise one command.
- You can now run the Photon drivers.
To run the graphics driver:
/usr/photon/bin/Photon & waitfor /dev/photon /usr/photon/bin/io-graphics -d...(See the "Devices supported" chapter in the BSP documentation for details on the graphics driver options).To use a usb mouse and keyboard:
/sbin/io-hid -dusb /usr/photon/bin/devi-hid kbd mouse &
- If you specify the -d and -p options for io-graphics, you must put the -d option before the -p, or else io-graphics fails. (Ref# 22670)
- The ROM monitor version (UBoot) that comes with the board initializes
the CPU frequency to 96MHz, but it should be 192MHz.
To avoid timing issues, be sure to get the latest version of the UBoot
ROM Monitor.
(Ref# 22446)
The IPL sets the frequency to 192MHz.
- Pressing the reset button will not reset the board properly. This is a bug in the ROM monitor.
(Ref# 22447)
Workaround: Use the IPL instead, or power down the board then power up again.
- The TCP/IP stack obtains a timer from the process manager.
This timer starts at 0. If the TCP/IP stack and a TCP/IP application that tries to connect to
a remote host start executing too soon, the TCP/IP stack may apply a time of 0 seconds
to ARP cache entry structures. If this occurs, you may end up with a
permanent ARP entry (i.e. one that never times out).
You can also end up with permanent, incomplete ARP entries that never
time out, and that the TCP/IP stack doesn't attempt to resolve. If this happens,
your host won't be able to communicate with one or (possibly) more remote
hosts (i.e. the ones the TCP/IP application in the OS image is trying to reach).
You can check for permanent ARP entries by running the arp -an command and examining the output. The only permanent entries listed should be for the IP addresses assigned to your host's interfaces; there shouldn't be any permanent, incomplete entries. If you find a permanent entry that isn't for the IP address of an interface on your host, and you didn't explicitly create a permanent entry, then you could be encountering this problem. (Ref# 21395)
Workaround: In the buildfile for your OS image, delay the start of the TCP/IP stack or the first TCP/IP application by at least one second, by using the sleep command (e.g. sleep 1) or some other delay mechanism.
