does anyone can share bootstrap loader and monitor to proceed st10f273m CAN bootstrap?

i can successfully enter to BSL over CAN, sending frame 0 with DLC 0 and after 128 frames with id 5 and first byte of my code. It works i can execute my code but the problem is that i cant send anything from st10. Documentation says that BSL routines preparing MO 2 to be TX object with id E6 and DLC 3 and should be send for rquest by sending remote frame...BUT IST NOT!!!!!!
