NOTE for V7 firmware:

There are 2 operation mode on flash memory:

1. Direct address mode( or address mode). this mode is available on all version of displays, can access full range of data in flash memory.
2. File mode. It also can use full range of memory sectors in flash.

To avoid the data access confliction between address mode and file mode, please use Reserve flash command to reserve a space for address mode: this command create a spcial file and assign a continues space to this file. then address mode can use this space as usual to avoid data confliction.
