Hello all,

As in title, I am having trouble of setting continuous refresh for global variables as I get the error in the "Expressions" saying "execution status prevented access."

My development environment is following:

OS: Windows 7 32 bit

CCS version: 6.1.0.00104 

MCU: TMS570LS1227

Board: TMDXTMS570LS12CNCD Hercules ARM Safety MCU controlCARD

Connection: XDS100v2

    I had previously reporting this in https://e2e.ti.com/support/development_tools/code_composer_studio/f/81/t/413892 

    With CCS 6.1.0.00104 there has since been a bug fix in TI Emulators version 6.0.14.0. From the description of TI Emulators version 6.0.14.0:

    Various bug fixes/enhancements for Hercules including CCS configuration issue for RM46L852, data trace and variable trace issue, enhancement to expose additional pseudo registers for Cortex-R, enhancement to enable run time memory access for Cortex-R cores.

    I have just tried with CCS 6.1.0.00104 and TI Emulators version 6.0.14.0, and with a RM46L852 or TMS570LS20216 was able to modify global variables while the target was running.

    If you do Help -> About Code Composer Studio -> Installation Details what version of "TI Emulators" is installed?

    Thank you for your prompt answer. I actually read your article but could not solve the problem.

    But anyway, it seems like the version is the key.
    Mine is 5.1.641.0 so I am trying to update it.
    (I am now struggling with the proxy setting... It's taking me like 1 hour already...)
