mcf54415 eSDHC

Dear all,

 

i was trying to see some signal out of the eSDHC controller, but i can't see any sign of activity.

Pinmux pads on the gpio controller has been set to eSHDC (alll as 0x03). Card is always

inserted.

Testing some commands, using an existing u-boot driver, or also with separate init test commands, i can't see any signal on sd_clk or sd_cmd.

 

Is it possible there is weird thing ? Also, i have seen that at least one coldfire model as mcf53xx has the eSDHC module not enabled. Hope is not the case of this mcf54415 chip.

 

Every help is appreciated.

Angelo
