I guess you are aware that SRDAM cannot just be used, instead it must initialized correctly before you can access it. Your master is also performing this initialization procedure, then? > Therefore I'm wondering -- will U-Boot be fine with such a boot mode, > usually systems start from flash (NOR or NAND), but here it's in RAM. > I believe it should be OK, but just want to make sure. It doesn't hurt when the device where U-Boot is booting from is writable. You have to take care not to try t<F12>o re-initialize the RAM in U-Boot, though.
