It looks to my uneducated eye most of the issues lie in that getting a suitable PORT(x), KERNEL_START, KERNEL_SIZE, FREE_MEM_START and FREE_MEM_END is non-trivial on the MIPS platform currently; probably because of the lack of a generic lzma/gzip/bzip2 framework to be used with. For me I used: #define FREE_MEM_START CKSEG0ADDR(0x94a00000) #define FREE_MEM_END CKSEG0ADDR(0x94f00000) I had to replace (you probably should move this from dbg.c to dbg.h): #define PORT(offset) (CKSEG1ADDR(AR7_REGS_UART0) + (4 * offset)) The load address is awkward, but I replaced your 0x8100000 in the Makefile with 0x94400000. Now, the big question is how to work this all out at compile time. :) As a side note, I would personally leave the DEBUG non-optional and turned on as it all disappears at runtime anyway, but I'm no kernel developer :) Again, thanks for this, it truely is great stuff.
