Question
HAL_MMC_ReadBlocks compilation error
Hi,
I am using HAL driver for STM32F4 microcontroller. Every thing is fine. But, I have the following compilation error for this macro (SDMMC_STATIC_FLAGS) from stm32f4xx_hal_mmc.c.
This macro was not found in the header file also. How to resolve this.
Kindly help.
