Compiler/AM6548: DDR clock speed

sarfaraz shaikh

Part Number: AM6548

Tool/software: TI C/C++ Compiler

I am using the custom board for AM65XX. in Uboot I did not find a DDR speed for AM6548 EVM IDK board.

Like in Beaglebone black in board.c file we can change the DDR frequency for custom board. In AM65xx Uboot SDK 6.0 where I can change the DDR Speed.

Thanks,

Hi Sarfaraz,

Seems DDR4 speed is set to 1600MHz (1600 MT/s) in DTS files:

u-boot-2019.01/arch/arm/dts/k3-am654-base-board-ddr4-1600MHz.dtsi

u-boot-2019.01/arch/arm/dts/k3-am654-ddr.dtsi

Regards,
Pavel

Thanks. So for changing the DDR frequency do we have to change these dtsi file ?
