Hello Wolfgang,

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?
Yes, it is.
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.
This is my understanding that I have to define these optioins: CONFIG_SKIP_LOWLEVEL_INIT and CONFIG_SKIP_RELOCATE_UBOOT in order to avoid re-initialization of RAM and copying U-Boot image in to RAM.
