Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 1. SH7086 1.1 Flash Memory Configuration The flash memory of the SH7086 (SH family) has two types of memory mats: a user mat (user area) and a user boot mat (user boot area). In addition to these, there is another area in which the flash memory write/erase control program is stored. This area is referred to as the boot mat (boot area).
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 1.3 On-board Programming Mode There are three on-board programming modes: boot mode, user program mode and user boot mode. The user boot area can be written to and erased in only boot mode. In boot mode, the user area and user boot area are once erased in their entirety. After that, the user area or user boot area can be written to by issuing a command, but their contents cannot be read out up until this state.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 2. Functionality of the Flash Development Toolkit The Flash Development Toolkit is an on-board flash programming tool for Renesas flash microcomputers, featuring a highly functional, easy to use graphical user interface.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 3. Method for Using the Flash Development Toolkit in Each Mode For a write to the user boot area in user boot mode or a write to the user area in user program mode to be executed, there must be the load module file for user program mode (shared with user boot mode) written in the area concerned.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 3.1 Connecting the E8a Emulator The E8a emulator, connected between the host computer and user system, has the facility to write the user application program to or erase the program written in a flash microcomputer’s internal flash memory on the user system (on-board) by using the Flash Development Toolkit.

Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 6.3 RAM Main Process The RAM main process involves transferring a library, erasing the flash memory, and writing to the flash memory. These processes are executed in the RAM. (1) Library transfer (FDTUMain.c) • LibTrans If commandID is prepareERASE (0x48), set FECS to EraseMode (0x01) and select the erase library. Otherwise (prepareUserAreaWrite, 0x43), set FPCS to WriteMode (0x01) and select the write library.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) • ScoBitSet Set the library transfer destination address in the FTDAR register, set the VBR register to 0x84000000, and set the SCO bit of the FCCS register to 1. There must be 4 or more of NOP instructions after the SCO bit setting.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) (2) Area selection (FDTUMain.c) To select the user boot area or the user area, set FmatsuUserBootMat (0xaa) or FmatsUserMat (0x00) in the FMATS register. There must be 2 or more of NOP instructions after the setting.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) (3) Flash memory erase (FDTErase.c) • EraseInit Select the user area and after specifying the operating clock frequency, initialize the erase library. For the operating clock frequency, the operating clock frequency specified by FDT is transmitted to the device in new bit rate selection. The library initialization uses this operating clock frequency.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) (4) Flash memory write (FDTWrite.c) • WriteInit Select the user area and after specifying the operating clock frequency, initialize the write library.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) • Execution of a write termination process (WriteFLASH) This is part of the flash memory write termination process. For details, refer to the sources of the files for user program mode. In write data reception (GetWriteData), receive the address where the data to write is stored and the address to which to write. If the write destination address is WRITE_END (0xFFFFFFFF), execute a write termination process.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 7. Programming Guide This section explains how to write a program using the flash microcomputer’s standard boot program. A sample program and the precautions to take are described. For details, see the hardware manual. 7.1 Functional Outline The microcomputer’s standard boot program is comprised of a transfer library, erase library and a write library. The functionality of the boot program is outlined below.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 7.2 Control Registers and Control Bits The following shows the library transfer and user boot area related control registers and control bits. (1) Selecting the functionality Use the FKEY register to select transfer and write/erase. Set the FKEY register to H’A5 to transfer the write/erase library, or H’5A to execute the write/erase process.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 7.3 Using the Libraries This section explains how to use the libraries. (1) Transfer Follow the procedure below to perform a transfer. 1. Select the write library or erase library to transfer. For the write library, set the PPVS bit (bit 0) of the FPCS register to 1. For the erase library, set the EPVB bit (bit 1) of the FPCS register to 1. 2. In the FTDAR register, specify the transfer destination address in the RAM.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 7.4 List of Module Facilities There are three libraries: Transfer library, erase library and write library. The functionality of the respective modules are listed below. – REJ06J0071-0100 /Rev.1.00 2009.
Flash Development Toolkit Method for Using the User Program Mode (SH7086 Application) 7.5 Module Specifications Specifications of the library modules are shown below for reference. For details, see the hardware manual. (1) Transfer start Name Type Functionality Parameter Input Return value Output Processing Transfer start None Library is transferred by setting the SCO bit of FCCS register to 1. Program transfer None For the write library, the PPVS bit (bit 0) of the FPCS register is set to 1.
