Dear friends,
I am working on hive based registry. After enabling the appropriate variables in Environment variables section, I made certain changes in my NAND.reg file which is as shown below-
; @CESYSGEN IF FILESYS_FSREGHIVE
IF BSP_NAND
; HIVE BOOT SECTION
;
; We want start both storage and device manager. Flags value is combination of
; 0x0001 Start storage manager in boot phases 0 and 1 to load the boot
; file system.
; 0x0002 Start device manager in boot phase 1 to load the boot file system.

But before any alternate boot I add some folder and I can see in next boot and add one more folder and unable to see in next boot.
NOTE- Observed one thing when the data/folder persist in the desired location(mounted device).. that time device does not ask for calibration test ..
I have also read various documents as shown below but still get no success:-
