STM3241G Evaluation board: unable to access SD card with SDIO 4-bit wide bus configuration and with SDIO DMA access for both 1-bit & 4-bit wide bus. Attempt to access SD card will always results in timeout error. 

Also i

nitialization code generated from STM32CubeMx for toolchain TrueStudio will always have 1-bit wide definition even when SDIO 4-bit wide is configured.

Use the examples under the HAL/Cube tree, should be some specifically for the EVAL board, along with others that could be ported.
