I just got two brand new of DoC Millenium (8 MB), and everytime I modprobe docprobe I see "DiskOnChip found at address 0xE0000" No Flash Chips Recognized. "DiskOnChip found at address 0xE2000" No Flash Chips Recognized. . . "DiskOnChip found at address 0xEE000" No Flash Chips Recognized. I also couldn't compile mtd/util/ but I think it shoudln't hurt DoC detection? Regards. Ming. ^ permalink raw reply [flat|nested] 12+ messages in thread

I wonder if DoC got damaged or they just keep using different flash? I will buy a new one and test again. Regards.
