I modified target/linux/ar71xx/files/arch/mips/ar71xx/mach-tl-wr741nd.c and re-compile.
I saw the changes NOT compiled, because i leave syntax error in the file.
I tried make clean. But this file was still ignored by compiler.
How could I make it compiled? Could any one tell me a solution?
BTW, Sure I selected 741ND profile!
