I try to write a block on a SDIO card. For that I need to set the wide bus (4-bit) operation mode (meaning data would be transferred on D[3.0])
On the datasheet of the STM32F103 it says:
Wide bus (4-bit bus width) operation mode is selected or deselected using
The device I plugged on the SDIO doesn t support the command 6. It only supports command 52 (IO_RW_DIRECT) and command 53 (IO_RW_EXTENDED).
Would anybody know how to set the SDIO bus width on 4 bits on a STM32F103?
Thanks in advance.
