How to run program from flash, for F28335: TI sensorless PMSM example (official - without any modification!)

I carried out these steps:
 
1. Opened mentioned example (C:\TI\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.0\HVPM_Sensorless_2833x) in CCS5.2, licenced
2. made new Build configurations (copy settings from existing F2833x RAM configuration)
3. exclude F28335_RAM_HVPM_Sensorless.CMD and include F28335_FLASH_HVPM_Sensorless.cmd linker file (-existing TI file in that project folder)
4. add section for dlog in the included cmd file:     DLOG:    > RAML4,PAGE = 1
5. define variable "FLASH" in project properties: CCS Build/C2000 Compiler/Advanced Options/Predefined Symbols
6. flash DSP with XDS510LC Spectrum digital emulator


Result:
when go in debug mode, enable Real time mode, BackTicker is live - Ok,
but after setting EnableFlag, DSP refreshes IsrTicker only once and then suddenly crashes!

Why??
How to make code flash executable??

Thanks in advance
