Compatct Flash board for Nucleo H735ZI.

Details

This board connects the compact flash to the NucleoH735ZI FMC as the 8bit true IDE mode. The connection is depicted below :

Compact Flash	H735ZI Pin	H735ZI Functionality
nCS0	PC8	FMC_NE2
IORD	PD4	FMC_NOE
IOWR	PD5	FMC_NWE
nWAIT	PD6	FMC_NWAIT
IRQ	PD2	EXTI2 ( active H)

STM32H735ZI configuration

The followings are the pin configuration of Nucleo board.

The CF interface of the STM32H735ZI must be configured as :

• One of the FMC SRAM memory space must be assigned to the NE2. The CF is assigned to this memory space.
• That memory space must be 8bt and must have asynchronous wait.
• If the IRQ is needed, assign PD2 as EXTI2. This is active H signal.

lso, short bridge have to be configured as the followings :

• PD8 : Cut SB12 to disconnect the STLINK VCOMM signal.
• PD9 : Cut SB19 to disconnect the STLINK VCOMM signal.
• PB6 : Short SB9 to assign LPUART1_TX to STLINK VCOMM signal.
• PB7 : Short SB34 to assign LPUART1_TX to STLINK VCOMM signal.

The USART3 is connected to STLINK VCOMM through the PD8 and PD9 by default. These pins are re-assigned to FMC. Thus, the LPUART1 have to be connected to the STLINK VCOMM through the PB6 and PB7.
