Dear all ST staff,

I found a small bug in CubeF7 v1.5.1.

Bug found at preprocessor macro definition of ''FMC_SDCMR_MODE_2'' at stm32f7 register definition files(stm32f745xx.h, stm32f746xx.h, stm32f756xx.h, stm32f765xx.h, stm32f767xx.h, stm32f769xx.h, stm32f777xx.h, stm32f7h).

It shows a case of the stm32f746xx.h below.

1.

/****************** Bit definition for FMC_SDCMR register ******************/

#define FMC_SDCMR_MODE 0x00000007U /*!<MODE[2:0] bits (Command mode) */

7.
+#define FMC_SDCMR_MODE_2 0x00000004U 
/*!<Bit 2 */

I think ''FMC_SDCMR_MODE_2'' is binary

value at B

it 2 set.

Therefore,

''FMC_SDCMR_MODE_2'' should be defined as ''0x00000003U'', but defined at ''0x00000004U''.

After this modification, I was success the operation of ''FMC peripheral(SDRAM)'' with using ''FMC_SDCMR_MODE_2'' value without using AL Driver API.

Plz fix until next release.

Best regards,

y_sharp.
