Q : Using the REva board with embedded RLink, the software is not able to communicate with the target. What should I do?
A : Check the board's power jumpers (see item xxx above) and the RLink's jumpers. See the documentation for how to set the jumpers according to your target.

Q : My REva board seems to be not powered when I plug the USB cable to the attached RLink. What should I do?
A : Check the jumpers in the power section of the motherboard. The board could be configured for being powered through the JACK.

Q : I use other programs that may have the cygwin1.dll file. What should I do?
A : The GNUARM toolchain uses the Cygwin library. There should only be one "cygwin1.dll" file in your system PATH. If you have installed other programs using Cygwin (such as WinCVS), then you will have to delete the oldest version of "cygwin1.dll". The same problem might appear with other related DLLs. If you experience compatibility problems between the GNUARM toolchain and some other program, you should contact the GNUARM group (http://www.gnuarm.com) and the provider of the other program that conflicts with it.

  • I use Windows Millennium: The GNUARM distribution does not work at all under Windows 98. It works under Windows Millennium but the installation program fails to add the toolchain's path in the "PATH" environment variable. If you want to use GNUARM under Windows Millennium, then you will have to add the path where the GNUARM executables are (usually "c:\Program Files\GNUARM\bin") to the PATH environment variable. To do this, you have to edit the "c:\Autoexec.bat" file and then reboot the PC.
  • I also use WinCVS on my computer: The files "tcl84.dll" and "tk84.dll" installed by the GNUARM distribution are not compatible with the latest version of WinCVS and prevent it from working. You will have to remove these files from GNARM directory for WinCVS to go on working. This will not affect the correct running of the Raisonance Simulator/Debugger.
  • I use another GCC toolchain: There are also potential compatibility issues between the different GCC toolchains. Those that we encountered were related to the GCC_EXEC_PREFIX environment variable. If you have this kind of problems, look at the gcc documentation to see the use of this variable. Depending on the other toolchains that are installed, you could have to modify it by hand.
  • I want to know the efficiency of the GNU compiler compared to other ones: To see how efficient the GNU compiler is, please follow the link: ARM C Compiler Comparison

Q : I cannot connect to my STR710 device with RLink! What should I do?
A : We found a problem for RLink on the STR710 (but not on the STR711, 712 or 715). There will be a software fix in the future, but for now, the best thing to do is to cut pin 17 of the 20-point connector of the RLink adapter.
