Hi ST Community, In SAI example, an audio file is in .bin. This file is flashed directly at @0x08010000 using ST-Link utility. But, I wanted to write the hex file to the particular memory address by program (not using ST-Link utility).

Is there a question here? You can write to FLASH in your program using the various HAL_FLASH_* calls. There should be examples in the relevant CubeMX repository for your chip.

Do you plan on writing the Windows side application replacing the ST-LINK Utility?

How do you propose to do the download? Via serial? Using X/Y-MODEM type protocol?

You can implement the target side code via the HAL Flash calls to erase and write to the memory area to be used for the binary data.
