AM3352: How to do DDR3 test on Uboot?

Daniel Cheng1

Part Number: AM3352


Hi Expert,

Is there any program to do DDR3 test on uboot?

I only know "mtest" can do it.

But 

The "mtest" command is considered deprecated.

So how to do DDR3 test on uboot?

Could you give me some hints to verify the DDR3?

Thanks

Daniel

    Hi Daniel, 

    As noted in u-boot/doc/README.memory-test, one option it to leverage u-boot built-in function get_ram_size() (see "common/memsize.c").

    “It is a little known and generally underrated fact that this code will also catch 99% of hardware related (i. e. reliably reproducible) memory errors.” 

    Best,
