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


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.
