One huge difference (among others) between the stm32f4 and stm32f1 devices is that the F4 have an integrated SDIO controller, where the F1 devices do not. On the F1, you're pretty much restricted to using SPI to access the SDcard. (I've written code for both families; (the F4 code done properly using DMA is actually quite a bit more involved). If you want to see my F4 code see the module "sdiosubs.c" on Github at https://github.com/Tubatstuff/Pertec-Interface-Tape-Controller If you want to see some F1, code, I'll have to rummage around a bit.
