Hi ,
I am using "HY-MINISTM32V 3.2 INCH LCD BOARD (VCT6)" this board .... in this SD card is on SDIO interface i would like change that one to SPI , because i would like to use UART4 and UART5 ..(These pins are used by SD card right now)....

any suggestions ......

Thanks
Vishnu

Hi,

You'd have to compile your own firmware to do this - but it is possible. On 1v73 you can choose whatever pins for the SD card you want.

However you'd also have to cut the tracks of the other pins leading to the SD card. It's quite a bit of effort.
