In the previous post, I mentioned that there is an error after rebooting Raspberry Pi. Well, after searching around the net and receiving reply from this forum. I think the issue may be due to the power supply. I used my smart phone charger for power supply and attached Acer USB Keyboard and Mouse to it.
However I’ve tried removing the keyboard and mouse from it and restart it but it is still the same. I didn’t shutdown properly though, which might cause SD card corruption.
I reformat my 8Gb SD card and I’ll inspect the problem again next week.
