  • [SOLVED] J-Flash crashes when using flash loader that has too many sectors?

    J-Flash V7.80d crashes when using a custom flash loader for 64MB (or higher) chips that use 4KB sectors. It does not crash when using a custom flash loader for 32MB (or lower) chips that use 4KB sectors.

    J-Flash V7.68c does not crash.

    C Source Code

    1. const struct FlashDevice FlashDevice =
    2. {
    3. // AlgoVer
    4. 0x0101,
    5. // Name
    6. "TEST",
    7. // Type
    8. 1,
    9. // BaseAddr
    10. 0x90000000,
    11. // TotalSize
    12. 64 * 1024 * 1024,
    13. // PageSize
    14. 256,
    15. // Reserved

  • Hello,

    we are not aware of such an issue with V7.80d.

    Is it possible for you to provide a simple reproducer setup (XML, ELF and custom flashloader project)?

    Best regards,
    Matthias

  • You can reproduce the crash by modifying "OpenFlashloader_CortexM_Template_EmbeddedStudio" as follows:
    Flash size: 64MB
    Sector size: 4KB

    - Put the contents of the attached zip file in C:\Users\xxx\AppData\Roaming\SEGGER\JLinkDevices
    - Start J-Link 7.80d
    - Select TEST/TEST loader
    - Click OK
    - Application crashes (silently)
