Functions
uint8_t	TCMDEXEC_stm32_internal_flash_write (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Write data to the internal flash bank starting from address 0x08100000.
uint8_t	TCMDEXEC_stm32_internal_flash_read (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Read data from the internal flash bank.
uint8_t	TCMDEXEC_stm32_internal_flash_erase (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Erase a range of pages in the internal flash bank. Only Erases for Flash Bank 2.
uint8_t	TCMDEXEC_stm32_internal_flash_get_option_bytes (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Get the option bytes configuration from the stm32 internal flash memory.
uint8_t	TCMDEXEC_stm32_internal_flash_set_active_flash_bank (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Given a 1 or 2, switches to the respective flash bank and runs the application stored there if present. Mostly useful for switching between 2 different version of the firmware (1 will be stored in Flash Bank 1, other will be stored in Flash Bank 2)
uint8_t	TCMDEXEC_stm32_internal_flash_get_active_flash_bank (const char *args_str, char *response_output_buf, uint16_t response_output_buf_len)
	Prints the active flash bank where the firmware boots from.
