Hi !

I'm in trouble for DM385 SD booting.

Kim,

Is this your custom board? If so, have you taken care of DDR leveling parameters in first stage u-boot?

Hi.

I have the same issue on DM385 IPNC. RDK ver.3.5.

I had compiled MLO and u-boot.bin(in Rules.make BINARY_MODE = sd, FULL_FUTURE).

The output is completly the same. MLO is booted but u-boot failed to execute from memory..

Is DDR requires additional adjustments when I switching between FULL_FUTURE/LOW_POWER, nand/SD?

Dmitry,

If this is your custom board, DDR3 for sure needs timing as well as leveling needs to be performed. Can you try to connect a JTAG and see whether the memory is fine or not?
