I am using LPC43s67 evaluation board.
I have a custom sd card addon which is connected through sdio interface.
The sd_cd pin is not available on my custom board.
I am using a 4GB SD card with FAT 32 format.
I flash the periph_sdmmc code, but unable to create file or write any test on the sd card.
I am not getting proper output from disk_initialize function.
I have provided the VDD and i am getting proper voltage for SD card interface.
Since i do not have the sd_cd pin I made the sdif_CardnDetect function return(0) manually.
Now hard error "Card Acquire Failed" is coming up.
Can anyone help to resolve the error?
