FT9XX firmware update over UART?

[Zetin]

Hi, I'm searching a solution for the FT900 MCU firmware update over UART.
Indeed it is mentioned about firmware updates  from USB (DFU mode) and UART. 
For the firmware updates in DFU mode, there exists the sorces but for the firmware update over UART there is almost none.
Does any one able to perform a firmware update over UART?

I can affirm we had it done, but we have a different approach (using external EEPROM instead of directly writing in flash) with XMODEM over UART at 921kbps.
I'm sorry I can't share directly the code, but I can help you find the way if you're interested.

The function you need to write is memcpy_dat2flash()
