STM32L151 SPI only sending zeros.

I'm trying to get SPI2 up and running to talk to another chip and I'm having some problems. I can see my SCK and MOSI traces on my scope but my DR register always has zero. I've even tried this right after SPI config:
SPI2->DR = 1;
TXE bit is high when I try this call.

I guess I'm lost at what to look at next.
