Dear all,

We use SD boot.


At Booting, We'd like to set the SD clock speed  as Normal Speed Mode (25MHz).

We understand that High/Normal can be chosen by BOOT_CFG1[3:2].

We tried these Field was set as 00 and 01 by GPIOpins.

We use the Internal Boot Mode (BOOT_MODE[1:0] = 0b10).
But the speed of the clock is 50MHz.


Can SD clock speed be set as 25MHz?
If there are the contents which we should set more, please tell me.

Best Regards,
