I managed to build a kernel, but booting won't work. I use the NEC Bootloader, and load the Image over a serial-connection to the Ram (address 0x8010000). The bootloader set the INTERNAL_REGISTERS_BASE to 0xab000000. If I understand the starting-process, the kernel normally searches it at 0xbfa00000 which is the address, before the Bootloader changes it. This is set in include/asm-mips/nile4.h . It gets changed to 0x0a000000 (set it smvr4181a.h). Now I change the address in nile4.h to 0xab000000, so that the kernel should use the correct address and then changes it to his 0x0a000000. I think this is the problem, because I get absolutely no output after the binary-download finished and should start. Hopefully you can follow my explanation of the problem (c: -- Grüße, Julian
