  • Do you set the project address to 0x10000 in compiler?


    If you don't need ethernet function, please use keil to develope it.

    You could get free license in here:

    Thanks.

    Hi chhuang16
    thanks for your response,

    Yes,I use ICP tool multiple project option to load second project in address(0x10000).

    But my second step is using ethernet to do FW update.

    Thanks.

  • Please Check "target.mbed_app_start" and "target.mbed_app_size" in second APROM code.


    For detail, you could refer to this mbed MCUboot demo:

    AGlass0fMilk/mbed-mcuboot-demo: Demo of mcuboot with Mbed


    Keil is a good choose.

    Thanks.

    Hi chhuang16

    So I need to set in 
    "M487\mbed-os\targets\TARGET_NUVOTON\TARGET_M480\device\TOOLCHAIN_GCC_ARM\M487.ld"
    for the second program?

    Thanks.



  • Hi Roger, 

    Did you set the orign into 0x10000 for the second program?

    For example: gcc_arm.ld

    ...  
    FLASH (rx) : ORIGIN = 0x00010000, LENGTH = ......
    ...

    Hi danchouzhou

    So I need to set in 
    "M487\mbed-os\targets\TARGET_NUVOTON\TARGET_M480\device\TOOLCHAIN_GCC_ARM\M487.ld"
    for the second program?

    Thanks.

    Hi Roger, 

    Try it! I believe will work.

    Could you provid the link of the source code (GitHub etc.) please? Thanks!

    Danny

    Hi Danny
    Thanks for your suggestion ,Problem solved.
    I set up MED_APP_START and MED_APP_SIZE in M480_mem.h .

    Hi Roger, 

    Great! 

    The main problem is that the linker does not know you have the offset 0x10000 for the second program. So the fuction call would still start from 0x00000. Ex.


    Also I found it in GitHub.Here is the link.
    M487.ld
    M480_mem.h
