RA6 bootloader broken when FSP was updated from 3.1.0 to 5.3.0

Hello,

We have a product with R7FA6M2AD3CFB microcontroller. The device has a bootloader (which had been created using FSP 3.1.0). The bootloader resides in the flash between addresses 0x0 - 0xFFFF.  The bootloader is programmed into the devices in our factory and cannot be changed later. Also, as we have many devices in the field, it is not an option to change the bootloader.

The task of the bootloader is to download the main program in some specific way (which is not relevant here) and write it into flash memory starting from address 0x10000.
On startup, if there is a valid main program in the flash, the bootloader jumps to the main program and continues execution from there.

The main program is compiled also with e2studio+FSP and then packed in some specific way (which is also irrelevant)

The Problem:
The system was working fine until we upgraded from FSP 3.1.0 to FSP 5.3.0. But after upgrading to FSP 5.3.0 and compiling the new version main programs with that, we encountered a big problem.  Now, as soon as the bootloader tries to jump to the main program (which is compiled with FSP 5.3.0), the device resets. Then tries to jump again and reset again... and so on infinitely.

Codes:

The code in the bootloader that jumps to the main program is this: 

#define MAIN_PRG_START_ADR 0x10000

void JumpToMainProgram(void){
    pFunction appEntry;
    uint32_t appStack;

    __disable_irq();

    R_MPU_SPMON->SP[0].CTL = 0;                                             //Disable Main Stack Pointer monitoring
    appStack = (uint32_t) *((__IO uint32_t*)MAIN_PRG_START_ADR);            //Get the application stack pointer (First entry in the application vector table)
    appEntry = (pFunction) *(__IO uint32_t*)(MAIN_PRG_START_ADR + 4);       //Get the application entry point (Second entry in the application vector table)
    SCB->VTOR = ((uint32_t)MAIN_PRG_START_ADR);                             //Reconfigure vector table offset register to match the application location
    __DSB();
    __set_CONTROL(0);
    __set_MSP(appStack);                                                    //Set the application stack pointer
    print_sdb("APP ");
    appEntry();                                                             //Start the application

    // Shouldn't get here
    while(1);
}

To move the main program after address 0x10000, we renamed the generated memory_regions.ld file as memory_regions_main.ld and change 2 lines of it as follows:

/*
FLASH_START = 0x00000000;
FLASH_LENGTH = 0x80000;
*/
FLASH_START = 0x10000;
FLASH_LENGTH = 0x70000;

And we changed the INCLUDE memory_regions.ld line to INCLUDE memory_regions_main.ld on top of fsp.ld file.

Configuration files for two FSP versions are below:

fsp_3_1_0_configuration.xml

fsp_5_3_0_configuration.xml

Auto-generated fsp.ld files for two FSP versions are below:

Auto-generated memory_regions.ld files for two FSP versions:

My Findings:

1. There are many differences in fsp.ld versions between 2 versions 

2. memory_regions.ld files have some address changes that I don't understand. Why are OPTION_SETTING register addresses different for example?

3. When I edit the memory_regions.ld file of the FSP 5.3.0 version and replace the contents with the contents of 3.1.0 version, I get this error dialog during compile:

- In the 5.3.0 version, when Independent Watchdog is added to the Stacks, the properties of iwdt looks like this:

This used to work fine in 3.1.0 with the same MPU.

I appreciate any help or suggestions, 

Thanks

  • Hello,

    It sounds like the watchdog timer resets the device. To find out the cause of the reset please read the Reset Status Registers RSTSR0, RSTSR1.

  • That was my first thought but it isn't. 

    Another finding is this:

    Our original bootloader was simply jumping to the main program. That was working fine when both apps (bootloader and main app) were compiled with FSP 3.1 but it didn't work when main app was compiled with FSP 5.3. 

    When I changed the bootloader like this:

    1. Write a signature value to the RAM on a specific location 

    2. Reset

    3. On reset handler, before initializing anything, check the signature. If signature is there, jump to main program.

    ... it works. But this doesn't solve my problem because I need to fix the devices in the field.

    So I am writing a main program that will be loaded by the original bootloader, then will replace the original bootloader by the new bootloader. 

    I know it is risky. If power goes off during flashing, device will be bricked. But there are not so many devices in the field yet and we will replace them if happens.

    Thx.
