Hi,

so you added sdhc stack into freertos_mpc5748g demo example. Seems you got devassert due to calling clock init again in vSDHCTask task. I think Platform_Init() can be commented out and DbgConsole_Init() with SDHC_fatfs_initialize() should be called in main after pin init.

BTW, there is sdhc_freertos demo directly within S32DS, so you can refer to it.

BR, Petr

any update?

Note: I have also changed the following.

PH8 pin tied low, e.g. setting with setting with OBE: Disabled, PUS: Pull-down, PUE: Enabled, Initial Value: Low and formatted the sd card.

Hi,

did you try the "sdhc_freertos_mpc5748g" demo example on your board?
Is this functional? if yes you can refer to it.
