-====== Firmware updates using the TCP/IP communication interface ====== 
- 
-===== Bootloader configuration ===== 
-In order to perform firmware updates with the OpenBLT through a TCP/IP network, double-check that the network communication interface is configured in "​blt_conf.h"​. The following macro should have a value of 1. If this macro did not yet have a value of 1, the bootloader should be rebuild after making the change. 
-<​code>​ 
-#define BOOT_COM_NET_ENABLE ​           (1) 
-</​code>​ 
- 
-===== Preparing Microboot ===== 
-The Microboot utility needs to be configured to connect to the correct IP address and port: 
- 
-  * Start Microboot by double-clicking "​\Host\**MicroBoot.exe**"​. 
-  * Click the "​**Settings**"​-button and select "​**OpenBLT using TCP/​IP**"​ from the dropdown box. 
-  * Click the "​**Options**"​-button to configure the communication parameters. 
-    * Set the hostname of your microcontroller system on the network. This is its IP-address, which is typically specified by the macro'​s BOOT_COM_NET_IPADDR in "​blt_conf.h"​. The default is **169.254.19.63** and will work if you have the system directly connected to your PC's ethernet port. 
-    * Set the port on which the bootloader listens for firmware update connection requests. This is specified by the macro BOOT_COM_NET_PORT in "​blt_conf.h"​. Typically, this is **1000** for the demo programs. 
-    * Check off the "​Automatically retry socket connections"​-checkbox if the system is directly connected to your PC's ethernet port. 
- 
-Once you saved the settings by clicking the "​**OK**"​-button twice, Microboot is now ready for action! 
- 
-===== Downloading the user program ===== 
-After building your user program, its S-record formatted firmware file can be downloaded to the remaining flash memory using the bootloader. In **Microboot** click the "​**Browse**"​-button and select your user program'​s firmware file. For the demo programs, this one is located in the "​.\**Prog**\bin\"​ directory. Once the firmware file was selected, the download should automatically start. ​

- 
-Once the download completed, the newly programmed software will be started by the bootloader. For the demo program'​s you can verify this by checking that the LED blinks. Congratulations! That's all there is to using the bootloader. 
- 
-===== Notes ===== 
-TODO Automatically retry socket connection...... 
- 
-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 BACKDOOR_ENTRY_TIMEOUT_MS in "​blt_conf.h"​ for the exact delay time.
