'asm' undeclared (first use in this function)

Hi,

Clean install of CCS 6.1 and TI-RTOS for Tiva 2.10.1.38. Import TCP Echo GNU example and compile. Gives the following error:-

C:/ti/tirtos_tivac_2_10_01_38/products/bios_6_41_00_26/packages/ti/sysbios/family/arm/m3/Hwi__epilogue.h:85:5: error: 'asm' undeclared (first use in this function)
asm volatile (
^

Guess because there is no double underscore in front of asm. Fix?

Thanks

    Looking at the Hwi__epilogue.h source file, I can see there were changes since that release to add double underscores to the asm statements.  But it isn’t clear to me why you are seeing a build problem.  Normally I think no underscores are allowed with GNU, unless an option is thrown to ensure ANSI compliance.  Maybe you have that set in your build?  Or, that might be a default in CCS 6.1?  I don’t know.

    Regardless, you can download a later kernel with the asm changes here: software-dl.ti.com/.../index_FDS.html 

    If you install this new version, you can select it over the previous kernel by specifying the ordering, as described in “3.3 Controlling Software Versions for Use with TI-RTOS” in the TI-RTOS User’s Guide.

    There should be a new TI-RTOS for TivaC release in the next few weeks, which will include the later kernel.
