| - | The BootCommander command line interface (CLI) program allows you to configure all communication settings via options on the command line. The following example demonstrates how to call BootCommander for making a firmware update with one of the demo programs. Just correct the “**-d**” option to select the PC’s communication device that the board is connected to. On Linux, change **COMx** to the full path to the communication device, for example **/dev/ttyUSB0**. | + | The BootCommander command line interface (CLI) program allows you to configure all communication settings via options on the command line.

| Depending on the configuration of the bootloader, there might be a delay between a system reset and the actual start of the user program. This is needed by design for the bootloader's backdoor functionality. Check configurable BOOT_BACKDOOR_ENTRY_TIMEOUT_MS in "blt_conf.h" for the exact delay time. | Depending on the configuration of the bootloader, there might be a delay between a system reset and the actual start of the user program.
