Learning to port to the NucleoH743 but no go on SPI

I am working on learning “Porting to a new flight controller board” and have opted to use an STM32H743 Nucleo board that I have at hand. I am trying to establish the ms5611 Baro via SPI as per the NucleoH743 hwdef.dat file. I am getting SCK and MOSI as expected but the CS line is never pulled low. I have tried changing the CS line to other pins which are then also consistently held high as well. Can anyone sneak a peak at the hwdef.dat file in the master and make a guess at what I’m fighting? P.S. I’m a noob and don’t know how to troubleshoot this yet. Cheers
