Updating firmware via serial port

[Je Ko]

Dears,

I am currently trying to update my firmware without using any development kit.
Instead, I am using this FTDI cable, and Tera Term.
Here is ho I proceeded :
– Wire 30 PA_10 / DB_RX / USBRX NA and 31 PA_9 / DB_TX / USBTX NA to the FTDI cable ;
– Power the mDoT ;
– Connect the FTDI cable to the computer ;
– Open Tera Term ;
– Connect at 115200 baud with no flow control ;
– Reset the board pressing enter to reach the bootloader prompt ;
– Compile a sample application and get the .bin from mbed ;
– Copy/paste the .bin into the teraterm directory ;
– In Tera Term, put the following command : “transfert ymodem nomBinaire.bin”

Then I am stuck in this situation (print C indefinitely) :

What did I make the wrong way ?
