| + | ===== Advantages ===== | ||
| + | * Not not any image may be flashed up, the used key must match. | ||
| + | * The images can not be easily disasembled. | ||
| + | * The readportection of the controller is activated. | ||
| + | * The code was further optimized and has a smaller size of 6K. | ||
| + | * Plausiblity and CRC check of flashed image. | ||
| + | |||
| + | |||
| + | ===== Advantages Bootloader 4 ===== | ||
| + | * Independent data chunks can be flashed at different times (with different start addresses). | ||
| + | * Gently usage of the flash memory: Only the flash areas are erased where new data is written to. | ||
| + | * Dedicated functions of the bootloader can be used from a flashed application, which may save space. | ||

In Bootloader mode, Netzer always has a fix, not changeable IP-address 192.168.97.60 as well as MAC-address 00-04-A3-00-00-00. It is important that the IP is not occupied by another device in the network. The update process is analog to the first variant. | + | For about two seconds, the Bootloader mode is active directly after plug-in of the power supply.
