stm32f303 bootloader problem

I can successfully load the code from stm32f407 processor to stm32f100 in my project by using f100's bootloader firmware and RS232 protocol.

However, I used the same(similar) way to load the code to stm32f303 processor, I never get the acknowledgement back from f303 on RS232 bus.  I read the application note (AN2606)numerous times but still could not figure out what is the unique thing I have to pay attention on this processor. Does anyone have good knowledge about this issue? Thanks in advance.

clive1,

I used realterm and type 0x7f. I saw TXD IS flashing but no RXD flashing.
