Problems attaching SD Card to STM32F4 Disc Board

Dear Forum,

I am trying to attach my SD Card using direct wiring, so no Core Board to host the STM32F4 Disc Board.

For this I connected the SD Card Holder as written in red into the scheme, but Mios_Studio keeps on telling me, that no SD Card is found...

Any help is appreciated, thanks!

Thanks for jumping in TK!

I just installed NG, but there is no sign of the default files and also the message of the missing SD Card:

Also the File Browser tells me, there is nor SD Card mounted (tried formatting the card both as MS-DOS Fat and ExFAT...)

So I must have done something wrong in the wiring though I checked many times, or my brand new SD Card Adapter is somehow broken...

Alright, now I see the problem - the notation for the "Connections to Pins on STM32F4 DiscBoard" has been added by yourself, and I agree, that the data input of the SD Card has to be connected to the serial data output of STM32F4, and vice versa.

Compare with the MBHP_CORE_STM32F4 schematic: http://www.ucapps.de/mbhp/mbhp_core_stm32f4.pdf

SDCard J1 DI -> MBHP_CORE_STM32F4 J16 SO (-> PA7)
SDCard J1 DO -> MBHP_CORE_STM32F4 J16 SI (-> PA6)

Problem solved :)

Best Regards, Thorsten.
