Missing Pin PD2 on STM32L433RCTxP

[SWend]

Hey,

I´m confused why i can not use Pin PD2 on Cube MX on the Nucleo Board L433RC even though it should actually exist because it exist when you select another STM32L433.

Without that Pin, i can´t use SDMMC. If i select for example the STM32L433RCTx, there is the Pin PD2. But if i try to use it with the Nucleo it wont work.

Any suggestions?

Do you confirm PD2 exist on the Nucleo schematic?

[SWend]

yes

That looks a little bit Strange. What DNF means? Do not fit?

There is not exist PD2 for STM32L433RCTxP but for STM32L433RCTx mcu

is also obvious from schematic you published. PD2 leads to an open solder bridge.

Also there is no SDMMC interface in STM32L433RCTxP mcu.

P makes the difference

ok, thanks. So i cant test SDMMC with L433RC without making my own board?

Perhaps try a NUCLEO-L476RG, and replace the chip.

Try asking your FAE to create one.

Find on the datasheet the pins which have SDMMC signals and which package gots it.

Maybe Discovery board if there is has microSD socket and signals wired.

ok, do you know the meaning of the two configs on the right side of the schematic?

Can i use PD2 when i solder the bridge?
