Other Parts Discussed in Thread: TMS320F28335

hello everyone

     My project DSP_INS can be build successfully by ccs3.3 under debug and release configuration, and can be build successfully by ccs4.2 under debug configuration,but it is failed by ccs 4.2 under release configuration,the error shows

file "C:/Program Files (x86)/Texas Instruments/ccsv4/tools/compiler/c2000/lib/rts2800_fpu32.lib<boot.obj>" specifies ISA revision "C28FPU32", which is not
compatible with ISA revision "C2800" specified in a previous file or on the command line.

Tms320f28335 is used in my project.


how can I modify the project or config the ccs? hope for your help. The attachment is my project.

    Hi,

    I would suggest you to go for the latest CCS version v5/v6 for FPU32 compatibility.

    It means that some part of the code is built with floating point enabled (rts2800_fpu32.lib), and some part of the code has been built without floating point enabled (likely your project).   If you do not want to use the floating point unit in hardware, then you need to link in the rts2800_ml.lib instead.  If you do want to use the floating point unit in hardware, then your project settings need to have this enabled (--float_support = FPU32).

    Thank you for your reply, the problem was solved by selecting the fpu32 support in the 'Runtime mode options'.
