    There are many internal reset generation sources existing in the RL78/F13 and RL78/F14. The reset control flag register (RESF) is used to store which source has generated the reset request. please find attached image for Format of Reset Control Flag Register (RESF).

    Hi,

    I have attached an example project on RA2L1 for your reference done on FSP2.3.0. Please update it to latest version if incase you use this example.

    You would have to edit the linker script, to change the start address in Code flash of the application, however the file memory_regions.ld is an auto-generated file so any edits are overwritten. Make a copy of memory_regions.ld and give it a different name, e.g. memory_regions_application.ld.

     

    and change the reference from “memory_regions.ld” to the name of the copy of the file you made, at the top of fsp.ld :-

     

    /*

    Linker File for Renesas FSP

    */

     

    INCLUDE memory_regions_application.ld

     

    in the file memory_regions_application.ld change the start address and size of the code flash :-

     

    FLASH_START = 0x00008000;

    FLASH_LENGTH = 0x38000;

     

    and then in the debug configuration for the application, in the “Run Commands”  at the bottom of the Startup tab set the Program counter, Initial Stack pointer and VTOR register to the moved location :-

     

    set $pc = *0x00008004

    set $sp = *0x00008000

    set {int}0xE000ED08 = 0x00008000
