CCS: CCS7 coredump

Other Parts Discussed in Thread: CCSTUDIO

Tool/software: Code Composer Studio

I'm having the same issue as https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/604509.

Do not think it is kernel related but some system tool was updated.

Kernel version:
uname -a
Linux  4.4.0-81-lowlatency #104-Ubuntu SMP PREEMPT Wed Jun 14 09:42:54 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

Reinstalled ccs7:
rm -rf .ti
rm -rf ti
Installed the latest CCS7 7.2.0.00013
at the command prompt:
~/ti/ccsv7/eclipse$ ./ccstudio
Segmentation fault (core dumped)

Then try and execute the xdctools via command line:
ti/xdctools_3_50_02_20_core/xs.x86_64U: error: can't create session manager error: can't create session manager: can't find a JVM; try setting the environment variable 'XDCTOOLS_JAVA_HOME' to the absolute path of any directory containing a 64-bit Java Runtime Environment (1.7 or greater); e.g., '/usr/lib/jvm/java-7-openjdk-a

so:
export XDCTOOLS_JAVA_HOME=$JAVA_HOME
which is:
XDCTOOLS_JAVA_HOME=/usr/lib/jvm/java-8-oracle

then cut and paste from the makefile to a command line:
"/home/tcmichals/ti/xdctools_3_50_02_20_core/xs"  xdc.tools.configuro -o configPkg -t gnu.targets.arm.A9F -p ti.platforms.evmAM437X -r release -c "/home/tcmichals/ti/gcc-arm-none-eabi-4_9-2015q3" -
Segmentation fault (core dumped)

This does work.
/home/tcmichals/ti/xdctools_3_50_02_20_core/xs

Think the issue is with the compiled in JRE with all of the TI tool set is the issue.
I have an strace dump showing it is calling the JRE in:

    Hi Tim,

    Thank you for providing the details of your troubleshooting.  Would you be able to provide me with the output of   java -version  for the java version in /usr/lib/jvm/java-8-oracle on your system.

    Thank you in advance.

    Martin

    Follow-up: with fix @processors.wiki.ti.com/.../Download_CCS
    ./ccstudio does work. But, xdctools /home/tcmichals/ti/xdctools_3_50_02_20_core/xs does not work.

    OK, this might be helpful:

    So, there is no JNI_CreateJavaVM function.

    export JAVA_TOOL_OPTIONS=-Xss1280k
    Works...
