How to use CMSIS to set a bit or register

[LMorr.3]

Each time I call SET_BIT to set a bit the register value remains at 0. All registers are 0 even after writing, as though they are read-only. For example, the following does not set the bit:

DMA2_Stream0->CR |= ((uint32_t)1);

What am I missing?

Thank you!
