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.
