Hello,
I am trying to get the SD Card Read/Write for my project. We are using FileX.
In SSP1.0.0, we are able to assess the SD card. But when we try to connect to an external SD card Slot (via Jumper wire). We encountered FX_MEDIA_NOT_OPEN error.
We connect the external SD card holder using 4 bit mode SD card interface.
In SSP 1.1.0. I encounter the same error (FX_MEDIA_NOT_OPEN) by using DKS7G2 on board SD card slot (S101 has been set). I tried to open the media using fx_media_open but got the FX_IO_ERROR.
I tested the clock line of the SD card, it is running @ 240kHz. We are now not very sure about whether it is a hardware or software issue (seem like for me both). May I know the FileX can support external SD card slot? Any Special tricks?
Thanks.
Regards
