MSP430FR6972: USE SOME OF FRAM AS RAM ,BUT MCU RUN IN LOCKED UP STATUS

Hi,

  My customer use FR6972 in an project. They want use 0x4400-0x5eff as RAM but failed. Can you help me to check the XCL which they revised. Is there any documents to say how to operate FRAM TO RAM?

Here is what they revised of XCL.

// -------------------------------------
// Data read/write segments
//

//
// The following segments are available for both
// the DATA16 and DATA20 segment groups.
//
// segment Usage
// ------- --------------------------
// DATA<nn>_Z Data initialized to zero
// DATA<nn>_I Data initialized by copying from DATA<nn>_ID
// DATA<nn>_N Data defined using __no_init
// DATA<nn>_P Data defined using __persistent
// DATA<nn>_HEAP The heap used by 'malloc' and 'free'
//
// segment Usage
// ------- --------------------------
// CSTACK Runtime stack
// TLS16_I Thread-local storage for main thread
//

// -------------------------------------
// Program and data read-only segments
//

//
// The following segments are available for both
// the DATA16 and DATA20 segment groups.
//
// segment Usage
// ------- --------------------------
// DATA<nn>_C Constant data, including string literals
// DATA<nn>_ID Initializers for DATA<nn>_I
//
// segment Usage
// ------- --------------------------
// INFO Information memory
// INFOA Information memory, bank A
// INFOB Information memory, bank B
// INFOC Information memory, bank C
// INFOD Information memory, bank D
// CSTART Program startup code
// CODE Program code
// ISR_CODE Program code for interrupt service routines
// DIFUNCT Dynamic initialization vector used by C++
// CHECKSUM Checksum byte(s) generated by the -J option
// SIGNATURE Signature memory
// JTAGSIGNATURE JTAG Signature memory
// BSLSIGNATURE BSL Signature memory
// IPESIGNATURE IPE Signature memory
// INTVEC Interrupt vectors
// RESET The reset vector
// TLS16_ID Thread-local initializers for main thread
// MPU_B<N> Memory Protection Unit border
// IPE_B<N> Intellectual Property Encapsulation border
// IPECODE16 IPE code
// IPEDATA16_C IPE constant data
//
// Notes:
//
// * The segments CSTART, ISR_CODE, and DIFUNCT, as well as the segments in
// the DATA16 and TLS16 segment groups must be placed in in the range
// 0000-FFFD.
//
// * The INFOx and INFO segments overlap, this allows data either to be
// placed in a specific bank or anywhere in the info memory.
//
// * The INTVEC and RESET segments overlap. This allows an application to
// either use the reset vector provided by the runtime library, or
// provide a reset function by defining an interrupt function associated
// with the reset vector.
//
// * To use the Memory Protection Unit, the symbol ?mpu2_init should be
// included in the application. The symbol '__iar_430_MPU_base' should be
// defined to the location of the MPU peripheral registers, and the
// registers '__iar_430_MPUSAM_value' and '__iar_430_MPUCTL0_value' to
// the value the registers MPUSAM and MPUCTL0 should be initialized to,
// respectively.
//
// * To include Intellectual Property Encapsulation (IPE), the library
// label '__iar_430_ipe_signature' must be included in the application.
// (One way to do this is to use the -g XLINK command-line option.) The
// symbol '__iar_430_MPUIPC0_value' must be defined to the value the
// MPUIPC0 register should be initialized to.
//
// * To include custom segments in the Intellectual Property Encapsulation
// (IPE) area, place them between the segments IPE_B1 and IPE_B2.
