Thank you, Andrew, Your mail direct me the correct way, I look at the build log, it shows that the redboot.bin is create with checksum, In my situation I use redboot.elf to gdb, and use redboot.bin to burn to ROM, redboot.elf is correct, redboot.bin is incorrect, I guess it is caused by checksum. Now I use command: arm-elf-objcopy -O srec redboot.elf redboot.srec then I burn to ROM using redboot.srec, Now it got correct result. Thank you again, Andrew.
