yes, the address is from 50008000.
i had read it and print it by uart, it's right ,see the codes above.

I will check if this is what i think should be it. As far as I remember the memory location was not all straight forward.

what i do is just under steps:
1, the cpu will read a little codes from tf,when power on.
2, by the little codes, it read jetqi to ram from tf, then call start_qi()
