Each BSP guide contains board-specific information and instructions on building an OS image for that particular board.
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.).
Known issues for this BSP
|
Please check the version of these release notes on the website for the most up-to-date information. |
- If you use the SPI with DMA enabled, the ADE (and hence the MME)
locks up.
This conflict occurs because the prebuilt DSP/BIOS and ADE image from TI was
compiled to use EDMA channel 1.
(Ref# 54350)
Workaround: When you start spi-master, don't specify the edma option.
If you have acquired the ADE code from TI, you might be able to to resolve the conflict by modifying the EDMA channel numbers on both the DSP and ARM systems.
- Only one headphone output (p8 on the board) is currently supported.
- The graphics driver requires both the QNX Advanced Graphics TDK 2.0.1 and a TI DSP image with the TES eVRU v2.03, configured for 120/8MB. You should obtain them separately from this package.
- You need to get the DSPLink package separately from this package.
- EMIF is not implemented in U-boot. This may cause the graphics to not work properly. You should use IPL booting for graphics.
- The spi-dm644x.so shared object doesn't support the SPIENA pin. The current driver supports only the first two chip selects.
- We haven't tested the ETFS driver because of a lack of flash devices.
- If you use gcc 2.95.3 to compile this BSP, you'll see
this warning, which you can ignore:
/bsp-TI-Jacinto-1.0.0-20071115-binsrc/src/hardware/devg/jacinto/mode.c:62: warning: passing arg 1 of `disp_phys_addr' discards qualifiers from pointer target type
- If you use gcc 3.3.5, you'll see these warnings, which you
can ignore:
- /bsp-TI-Jacinto-1.0.0-20071115-binsrc/src/hardware/can/jacinto/driver.c:162: warning: comparison is always false due to limited range of data type
- /bsp-TI-Jacinto-1.0.0-20071115-binsrc/src/hardware/devg/jacinto/mode.c:62: warning: passing arg 1 of `disp_phys_addr' discards qualifiers from pointer target type
- SPI0 is inoperable because the dra446.h header file uses the incorrect
base address for SPI0.
(Ref# 52270)
Workaround: Edit dra446.h and change this line:
#define DRA446_SPI0_BASE 0x01C41800
to this:
#define DRA446_SPI0_BASE 0x01C4CC00
- 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.
