Normal
mode(Default)
Normal mode is the default operation mode for the LP-8x4x. Use this mode to
perform additional tasks and configuration. Programs are also executed in this
mode.
Quick
mode
Quick mode is used to bypass the LP-8x4x boot screen when booting form a
microSD/microSDHC card, so as to speed up the booting process.
OS update mode
This mode is used to update the OS image. Note that the Linux OS image is
only suitable for the LP-8x4x. If the LP-8x4x cannot be booted or operated in
normal mode, use this mode to update OS image again. Ensure that you
backup any important files, before updating the OS image. For more
information, refer to the “LP-8x4x OS update manual”.
