Hi,

I use:
stm32f4 (LQFP100)

I want to:
1. Use FSMC bank1 to control LCD
2. Use FSMC bank2 to control NAND memory
3. Use chip select to control active chip

Problem:
Chip select for bank1 (NE1) and chip select for bank2 (NCE2) is both placed on pin PD7.

Question:
Anyone know if it is possible to use bank1 and bank2 somehow, perhaps use GPIO to control the chip select signals on the two chip?

According to manual:
2. For the LQFP100 and BGA100 packages, only FSMC Bank1 and Bank2 are available. Bank1 can only support a multiplexed NOR/PSRAM memory using the NE1 Chip Select. Bank2 can only support a 16- or 8-bit NAND Flash memory using the NCE2 Chip Select. The interrupt line cannot be used since Port G is not available in this package.

Regards,
Rygel
