Hi, after going through the boom code I found out, that setting the 'autostart' variable to 'no' brings me a little closer to what I want. But finally I end up in the enable_interrupts() at the very end of do_bootm(). This freezes my system. The reason for this is the Linux kernel image that is loaded to address 0 and that overwrites the vector table. So reenabling the interrupts in U-Boot with Linux interrupt table is a bad idea.
So what's the best idea to fix this? I could copy the vector table onto the stack in do_bootm() and copy it back just before reenabling the interrupts. Any better idea?
