[Sugar-devel] Reflashing XO1.5 with newer OS

[Harpreet Sareen]

 Hi,

I reflashed my XO 1 today with the latest OS 852.img but on startup, it
shows the Invalid System Date message with " :( " smiley. Even before the
update, it used to show the message and the rest things are functioning
fine.

****************************************************************
Invalid System Date
OLPC C2, 256 MiB memory installed S/N CSN74901B4F

****************************************************************
How to rectfiy the problem?

Regards
Harpreet
