I 
am trying to boot seL4 on beaglebone white. I have an initial code just 
to configure the DDR2 memory at range 0x80000000-0xbfffffff.


As
 we can see below, the start address is the virtual address 0xf0000000  
but at this point I have no MMU configured. I was thinking that the 
segment .boot should be the code to prepare all details about 
MMU/D-CACHE/I-CACHE but it's not what gdb is understanding based in the 
elf header.


Someone
 could explain to me how is the kernel boot; what do I have to 
consider. I guess that beaglebone is not supported but this is exactly 
my goal, to make seL4 boot on beaglebone.


Any help or suggestion is very welcome.

Sincerely,
Jorge Ventura
