How to make ssp1 of imx28 board to detect sd card?

[pt]

Hi Qiang_FSL, igorpadykov, raymondwang, JackLee1z,PeterChan

I am using freescale linux bsp on imx28 board. I have loaded linux image on sd card and inserted the sd card on sd1 to boot up.

Set boot mode select switch to 1010. But it sends error codes.The sd card is not detecting.

How to make ssp1 to detect sd card ?

I have seen that ssp0 pins are configured in mx28evk_pins.c file.

To solve the above issue, I have changed this according to ssp1.

Do I have to edit any other files?

Hi Pt

for SSP1 boot, the boot argument  (for example "gpmi") must be replaced by the "ssp1" at the

kernel command line to enable the pin mux for SSP1 port.

With OBDS test mx28_sd.c you can check hardware (read/write SD test).

Hi igorpadykov

I have changed the boot_stream command as

noinitrd console=ttyAM0,115200 root=/dev/mmcblk0p3 rw rootwait ip=none ssp1

and set boot mode select switch to 1001.

But I am getting the following error.

#define ERROR_DDI_SD_MBR_NOT_FOUND (ERROR_DDI_GROUP | ERROR_DDI_SD_DRIVER_GROUP | 0x1D)

0x8020A01D ?
