Hi All,
I am using LPC43s67 EVM Board, as per design requirement i have to use micro sd card with SDIO interface,
so in my custom design am using micro sd card connector PFA,
i am attaching connection i made for micro sd card,
confusing for me is that in LPCopen periph_sdmmc code DAT3 pin is assigned to P1.12 and CD pin is assigned to P1.13,
but in my connection i can not use CD and DAT3 pin as it is a single pin coming from micro sd card,
so tried connecting CD/DAT3 pin on micro sd card to P1.13 of EVm Board but card is not getting detected,
i tried giving directly GND signal to P1.13 and CD/DAT3 pin of micro sd card to P1.12 of EVM Board ,
so here card acquire is getting failed,
is there any issue in periph_sdmmc or in my design or i have to change something,
i have attached all the related files,
please suggest it will be helpful for me,
