Hi Ross, Thank you for your reply.
As for the command "fis write", I used a serial blaster contributed by Curtis Monroe from TS-7200 yahoo group. I think his main contribution is to enable "write" action to rewrite eeprom. Therefore, this "fis write" may be a little bit different from FIS. So I guess the problem should be the initialization code of my ecos. But I have no any idea about how to do some changes in ecos to make the compiled RedBoot recognize my flash. Could you please offer me some hints about this part of work? Thank you so much.
