  • [ABANDONED] Relocation R_ARM_ABS32 to weak symbol *** is invalid

    Hi,

    I've imported an IAR project, with no configuration modification, while linking I got 'Relocation R_ARM_ABS32 to weak symbol '****' is invalid' error.

    segger-as: version 2.10 segger-cc: version 10.6.2 segger-ld: version 3.04

    The functions are defined as weak :
    __attribute__ ((weak)) void tud_cdc_rx_cb(uint8_t itf)

    No matter the weak function is implemented or not, this error is generated.

    Linker command:
