The MLO be copied and executed from the DDR（address 0x80000000）？

Y tck

HI.

we want to do something different from starterware,only use the "MLO" image,that means the “app” image is embedded into the MLO image.

So,The MLO must be copied and executed from the DDR（address 0x80000000）,and we find it is possible in the TRM,but failed actully.

our steps are (based on bootloader project of the starterware) :

1.modify the CMD file.

2.modify the build opition (post-build steps \command) ,change the address.

3.load the "MLO" to the SD card.

How to resolve this problem?

Please suggest

Thanks

There are some issues with this. The ROM Boot loader does not know anything about connected DDR. It loads MLO into internal RAM so the size of your APP would be limited to that space. You might enable DDR from your app and load further parts of your software later but that is essentially not any different than the two-stages boot loader concept used now. What is the reason you can't use that?

Regards.
