I received this error compiling a rather simple file.

This is the command line

:"C:/ti/ccsv5/tools/compiler/msp430_4.2.1/bin/cl430" -vmsp --abi=eabi --code_model=small --data_model=small -O0 --opt_for_speed=5 --include_path="C:/ti/ccsv5/ccs_base/msp430/include" --include_path="C:/Users/cbenson/Multi/Track-It 6700/inc" --include_path="C:/ti/ccsv5/tools/compiler/msp430_4.2.1/include" --advice:power="all,-2,-3,-5" -g --gen_acp_xref --gcc --gen_acp_raw --define=__MSP430F4794__ --define=MULTI --define=CCSV5 --verbose_diagnostics --diag_warning=225 --display_error_number --optimizer_interlist --remove_hooks_when_inlining --gen_opt_info=2 --printf_support=nofloat -k --c_src_interlist --asm_listing --output_all_syms --check_misra="required" --misra_advisory=suppress --misra_required=remark --preproc_with_compile --preproc_dependency="APDS-9300.pp" "../APDS-9300.c"

This is the line which caused the error:

	CmdReg.cmd = 1; // this is a command

The fault went away after turning OFF MISRA checking. 
I can live without MISRA, but it is like having a second set of eyes looking over ones code.

We're going to need a test case so that we can reproduce the problem. At the very least, we'll need to see the definition of CmdReg.

Thank you for the test case. I have reproduced the problem and have submitted SDSCM00048440 to track this issue. The problem is that MISRA checking is choking on an anonymous union. Anonymous structs and unions are not legal in strict ANSI mode, and MISRA emits a warning if you are not using strict ANSI mode. The workaround is to give the union a name and use it for all accesses.

Thanks Archaeologist. The wiser choice might be to use bit flags rather than the bit field anyway.
