MSPM0L1106: Flash memory reservation

Alan Chan
Prodigy 200 points
Part Number: MSPM0L1106
Other Parts Discussed in Thread: SYSCONFIG, UNIFLASH

Tool/software:

Hi Team,

In MSPM0L1106, it has 64KB flash memory. The firmware code size is already more than 40KB.

Is it possible to reserve 1KB flash memory, 0x7C00 to 0x7FFF, for data memory and program code will not be generated in this area?

Thanks.

    Yes you can modify the .cmd file to define section with specific flash area.

    Hi Yuhao,

    Thank you for your support.

    I found that there is one .cmd file in my project folder, device_linker.cmd, under directory, <project folder>\Debug\syscfg\. It seems that it is a generated file from CCS. Where should I modify it?

    Hi Yuhao,

    Furthermore, the following is my proposed modification. Will this cause any overlap error with FLASH?

    MEMORY
    {
    FLASH (RX) : origin = 0x00000000, length = 0x0000FFF8
    SRAM (RWX) : origin = 0x20000000, length = 0x00001000
    BCR_CONFIG (R) : origin = 0x41C00000, length = 0x00000080
    BSL_CONFIG (R) : origin = 0x41C00100, length = 0x00000080
    FLASH_DATA (R) : origin = 0x00007C00, length = 0x00000400    <<- Added
    }

    (Remark: .cmd file restored to original after compilation.)

    To modify the cmd file manually, first you need to copy the cmd file to the project. Then please disable the cmd generation in SysConfig.

    Hi Yuhao,

    After the changes, I got the overlap error as my expected. Can you suggest how to modify the .cmd file?

    Please note there should not be any overlay on FLASH area. For example, FLASH (RX) : origin = 0x00000000, length = 0x0000FFF8, means it contains FLASH from 0x0000 to 0xFFF8.

    Hi Yuhao,

    Yes, I understand about it. This is the reason why I create this ticket.

    I want to know how to prevent the code generation at certain memory in between, eg. 0x7C00 with 1K data skipped for my case?

    AlanC.

    TI__Genius 9800 points

    You need to define two parts of FLASH, one is FLASH1 for 0x0000-0x6bff, the other one is FLASH2 for 0x8000 - ...So  0x7C00 with 1K data will be skipped

    Then you need to define section as 

        .text   : palign(8) {} > FLASH1 | FLASH2

    Hi YuHao,

    I modified the cmd file as you suggested as below, but there is still error on compilation as below.

    According to 10.5.5. The SECTIONS Directive — TI Arm Clang Compiler Tools User's Guide, you need to use >> rather than >. And please remove palign(8). I think you can modify .text only and keep others as default. Here is my test, I create FLASH1 and FLASH2 for .text used only.

    Here is another different method.

    1. create different '.text' and put different function into them separately. Here is an example code.

    Hi YuHao,

    Thank you for your support. I modified the .cmd file as following, but the same error was resulted.

    I also tried your provided project, Attritube_memoryAllocation_C. However, the project cannot be compiled with the error attached.

    No you need to use >> rather than > in SECTIONS of cmd file.

    Here is my test code as reference. I put the .text part in FLASH1 | FLASH2 by '.text   : {} >> FLASH1 | FLASH2'

    Hi Yuhao Zhao,

    Thank you for your support. Eventually, I can make my code compiled. But I still have question on it. I made 2 version as below.

    The left one is the one that I can compiled with my code. However, it will leave some un-used space in section "FLASH" now. Later, it may cause compile error when the code size is increased. So I tried to group the FLASH and FLASH1 together and created the right side. With the right one, there is compile error as below.

    Is it possible to group FLASH and FLASH1 together and how?

    Hi Yuhao Zhao,

    I am sorry to tell you that UniFlash reported error during firmware download through BSL as below.


    After I modified the cmd file by adding palign(8) to the line ".text : palign(8) {} >> FLASH1 | FLASH2", it will cause compile error. Is it able to overcome this issue?
