I'm trying to use arm-none-eabi-gcc (with several versions such as 10.3-2021.10) on windows to compile a dynamic library for ARM Cortex-M33; If I use compile option with -mcpu=cortex-m33, the build fails with an error "warning: thumb-1 mode PLT generation not currently supported collect2.exe: error: ld returned 1 exit status。".
Here is an example of my compile and result:
arm-none-eabi-gcc.exe -fPIC -mthumb -mcpu=cortex-m33 -mfloat-abi=hard -mfpu=fpv5-sp-d16 -fPIC -shared -nostdlib -nostartfiles -fdata-sections -ffunction-sections -Og -g0 -o libexternal_qrcode.so
arm-none-eabi/bin/ld.exe: libexternal_qrcode.so: warning: thumb-1 mode PLT generation not currently supported collect2.exe: error: ld returned 1 exit status。
however, if I change compile option to -mcpu=cortex-m4, the buid succeeds.
Here is my GNU binutils version:
$ arm-none-eabi-gcc --versionarm-none-eabi-gcc.exe (GNU Arm Embedded Toolchain 10.3-2021.10) 10.3.1 20210824 (release)Copyright (C) 2020 Free Software Foundation, Inc.This is free software; see the source for copying conditions.

Where could I download the 2022 version GNU? The lateset version in this website(developer.arm.com/.../gnu-rm) is 2021.10
