Used CCS6 beta4 to create an example project for a Tiva launchpad, using the GNU v4.7.4 (Linaro) compiler which was installed by CCS. Attempting to download the program fails with:

The same Tiva Launchpad works with examples compiles with the TI ARM compiler, so suspect this is a software problem.

The example project which caused this download failure is attached. The attachment also contains a debug_server.log file, which is the debug server output when the download failure occured. 1423.ARM_GNU_hello_world.zip

    The problem was originally found on CCSv6 beta 4 installed on Windows XP 32-bit.

    The same error is reported with CCSv6 beta 4 installed on CentOS 6.5 32-bit and CentOS 6.5 64-bit. As per the original Windows XP system, the CentOS systems can debug a program on the Tiva launchpad which was compiled with the TI ARM compiler.

    Chester,

    This looks like it is related to a known bug with our erase necessary pages algorithm during Program Load. This bug will be fix for the CCS6.0 GA release.

    In the mean time, you can work around this issue by modifying the default erase option to Erase Entire Flash (the "Use the Erase Options Specified Below" option in the On-Chip Flash view).

    Please let me know if this works.

    Thanks,

    Ricky

    Selecting to Erase Entire Flash allowed the program to be loaded without error.

    However, the program failed to reach main when run in the debugger, but that will be the subject of a new thread if found to be a problem with CCS.
