This is your THIRD thread on this topic.

Like I told you yesterday, you'd need to write WORDs to the GPIO->ODR, and you'd need those correctly BIT aligned with the pins you're using.

42 MHz seems very optimistic, people doing this professionally would choose an FPGA, or hardware to do this.

I've posted examples of DMA to/from GPIO pins, using internal/external clocks. Suggest some Google Foo, and serious consideration of what you're doing.
