Hi,
Thanks in advice for your help.
I have a custom board based on imx28. The custom board has 3 ssp enabled. On ssp2 I have a sd card reader, the sd is connected on spi with Texas Instruments mode 4pins(miso,mosi,sck and ss0). The configuration pins is here:
{
.name = "SSP2 MOSI",
.id = PINID_SSP2_MOSI,
.fun = PIN_FUN1,
.strength = PAD_4MA,
.voltage = PAD_3_3V,
.drive = 1,
},
{
.name = "SSP2 MISO",
.id = PINID_SSP2_MISO,
.fun = PIN_FUN1,
.strength = PAD_4MA,
.voltage = PAD_3_3V,
.drive = 1,
},
{
.name = "SSP2 SCK",
.id = PINID_SSP2_SCK,
.fun = PIN_FUN1,
.strength = PAD_4MA,
.voltage = PAD_3_3V,
.drive = 1,
},
{
.name = "SSP2 SS0",
.id = PINID_SSP2_CS,
.fun = PIN_FUN1,
.strength = PAD_8MA,
.voltage = PAD_3_3V,
.drive = 1,
},
also I have a gpio pins for sd detect. I need to developer a driver for sd card reader.
What would be your workflow in this case? try to work with mxs-mmc driver? or simple enable spi-mxs driver and develop a reader ? or try mmc-spi driver?
I'm new with this board and I'd like to know the best practices.
Thanks
