Description (last modified by Quozl) (diff)
An XO-1.75 B1 with Q4B05 with an "md" tag will brick if the RTC loses power, or if enough time has elapsed since the "md" tag was created in factory.
Diagnosis: OpenFirmware serial port shows an ok prompt after an error Unsupported SPI FLASH ID. Using flash-open manually at this point shows no error.
Workaround: flash q4b05jt (svn 2402) or later.
Prevention: manually change the "md" tag to an "MD" tag, before the time has elapsed, or before the RTC loses power.
