Sdio DMA code generated by the Cubemx tool does not work

Near the row in learning to use ST's Cubemx tool, so take the Atom Electron board to do the software debugging target board to do the test.

From porting the serial port, FreeRTOS waits all very smoothly, but when does the sdio transplant the time discovers a strange phenomenon, each time writes the card, will receive a wrong callback. So in the 21IC of the St Forum published the relevant posts.

Also very grateful to 21IC Netizen huzi2099 help.
