st-flash:tldr:40371

This command is used to write a firmware file (with a .bin extension) to a specific memory address on a microcontroller using the st-flash utility.

Here is the breakdown of the command:

• st-flash: Refers to the st-flash utility, a command-line tool for flashing and testing STM32 microcontrollers.
• write: Is the specific sub-command or action being performed by st-flash, which is to write data to the microcontroller's memory.
• ${firmware}.bin: Represents the path and name of the firmware file being written. The ${firmware} is a placeholder that should be replaced with the actual filename without the extension.
• ${0x8000000}: This specifies the memory address to which the firmware file is being written. In this case, the address is given in hexadecimal format (prefixed with 0x), and 0x8000000 usually corresponds to the start address of the flash memory on an STM32 microcontroller.

To use this command effectively, you need to replace ${firmware}.bin with the actual firmware filename you want to write, and make sure the firmware file is located in the same directory as the command is being executed.
