The latest arm-none-eabi-gdb version 12.3.Rel1 takes 20+ seconds reading symbols from elf file

Hi All,

I have recently updated the arm toolchain from version 10-2020-q4-major to 12.3.rel1. The arm-none-eabi-gdb included with version 12.3.rel1 is taking about 20 seconds to read symbols from elf file.

Is this a known issue? Can the user update some settings during the GDB client setup to avoid this delay?

  • Hi Avi,

    I'm having the same issue after upgrading to v12.3.1.  I've tried using an older ELF but it is still slow at reading.

    Let me know if you find a workaround and I'll do the same.
