The host ID is stored at address 0x1000 in the flash, which is used for code.<br /> The reason it works in a fashion is that the first byte is something different from 0xFF, which means the flash is not being overwritten. Instead it simply uses the code that happens to be there as the host ID.</p> <p>I will report this to the team, and update the case when I know more.</p> <p>Best regards<br /> Torbjørn</p><div style="clear:both;"></div>
