Not able to access the sdram bank 1 in stm32h757

[Aarra.1]

Hello,

I'm trying to access the SDRAM for stm32h757i-eval board and I'm able to successfully store data in the bank 2 i.e, from address 0xD0000000 on wards.

But I'm not able to store any data in the bank 1 i.e, at address 0xD0000000.

even during assigning the initial bank in the stm32 cubemx software the option for bank 1 is not available.

kindly let me know what part I'm missing out.

Thank you

The SDRAM chip is connected to bank 2 pins (SDCKE1+SDNE1). The bank 1 pins are not connected, hence it won't let you select them.

Guessing you meant 0xC0000000.
