CCS/TMS320F28377S: Writing a binary file into flash

Part Number: TMS320F28377S


Tool/software: Code Composer Studio

Hi everyone, 

I am working on my bootloader, so I'm trying to write data into Flash sectors. When I try to write data by hand, it works. But when I try to write a whole binary file into memory, it puts zeros everywhere, I cannot see the written data (it's not about security and I'm not even sure data is being written). I send my binary file using realterm. It worked fine with a STM32 microcontroller. Do you have any idea why the write operation is not being done? Thank you in advance.
