SUMMARY
When migrating your boot loader from Windows CE 2.11 to Windows CE 2.12, you must ensure that the following change is made:

Before compiling, make a code change to the SOURCES file for Nk.exe and the boot loader as shown below to reflect the LDEFINE flags as appropriate: !IF "$(_WINCEOSVER)"=="300" || "$(_WINCEOSVER)"=="212"

LDEFINES=-subsystem:native /DEBUG /DEBUGTYPE:CV /FIXED:NO

!ELSE

LDEFINES=-subsystem:native /DEBUG /DEBUGTYPE:BOTH,FIXUP

!ENDIF



MORE INFORMATION
ROMIMAGE gives unpredictable results if EXEBASE is not specified for Nk.exe. The EXEBASE value is also ignored if KERNELFIXUPS=on (default case). On x86 systems, the definition of EXEBASE is very significant because in the Init.asm file, EXEBASE is used by OFFSET32 in the following line: mov ebx, OFFSET32 PagingEnabled However, OFFSET32 is resolved at link time and EXEBASE is used to determine the 32-bit number. If EXEBASE is not present as a definite value when ROMIMAGE is executed, the system will malfunction. Updating EXEBASE works around this issue.
