  • Page 6: Introduction

    This document describes the procedure to start an emulator debugging session. There are 2 possible approaches: 1. Using external RAM for program code 2. Using MCU internal Flash memory for program code A comparison between these 2 possibilities is listed in section 5.1 AN-910011-18 - 6 - © Fujitsu Microelectronics Europe GmbH...

  • Page 7: The Fr Emulation System

    1 The FR Emulation System 1.1 Hardware of the Emulation System for the FR-family Fujitsu provides a complete emulation system for their 32bit RISC-MCU’s of the MB91360- serie. Figure 1 shows this emulation system, it consists of the Main Unit MB2197-01, the Evaluation-Board MB2197-120 and the target StarterkitMB91360.

    0xFFFFF, the Eva-Chip must be set to EXTERNAL-ROM-mode because the debugger can upload the code only to the external SRAM of the evaluation board. The debugger can’t upload the code to the MCU-internal flash memory. AN-910011-18 - 8 - © Fujitsu Microelectronics Europe GmbH...

    Chapter 3 Setting the MB91FV360 to External ROM-mode Fujitsu provides a set of batch files (start_ram.prc, etc.), which can be called form the debugger of Softune Workbench. “start_ram.prc” is the main procedure file which calls other procedure files subroutines. Sub-procedure files CS0_ADR_000000h.prc,...

    Softune’s Workbench resets the MCU to internal mode. Now mode data and reset vector can be set in external SRAM by the sequence of the batch file “start_ram.prc”. This batch file is called before the application is loaded to the emulator. AN-910011-18 - 14 - © Fujitsu Microelectronics Europe GmbH...

    Beside the automatically execution of the procedure file before loading the application (set in the debugging configuration, refer to section 3.2), the procedure file can be called manually via the command window of the debugger (Figure 9) or by the command batch start_ram.prc. © Fujitsu Microelectronics Europe GmbH - 15 - AN-910011-18...
