c - Handling hardware with polyspace -


i working mathworks polyspace code analysis. have hardware register write key+mode , read register check value in register equal mode.

the problem is, polyspace considers 'always fail' writing , reading different values in consecutive steps.

is there option in polyspace handle issue.?

since key+mode different mode, polyspace logically consider test your_hardware_register == mode failed (fortunatly).

it seems key , mode bit flags register. see 2 options:

  1. use bitwise , operator test register : if (your_hardware_register & mode)

  2. make register volatile (by adding qualifier volatile declaration of register) polyspace consider can take value (including mode).
