Known problems

objcopy

The latest GNU binutils, also used in Arm Embedded GCC, have a problem when running on 32-bit machines, and objdump fails to generate .hex files. The bug affects both Windows and GNU/Linux machines. 64-bit builds are not affected. The bug is documented as 1810274.

The current solution is to upgrade to 8.2.1-1.2; the workaround is to override arm-none-eabi-objdump with an older binary.

GDB

The GDB binary supplied with this release has problems loading the symbols from applications compiled with -flto, it will either crash with segmentation fault or throw an assert.

The bug reports:

• https://sourceware.org/bugzilla/show_bug.cgi?id=24145 (to the GDB maintainers)
• https://bugs.launchpad.net/gcc-arm-embedded/+bug/1813553 (and to the Arm maintainers)

The current workaround is to use the GDB binary provided in the previous v7.x release.

Easy install

The toolchain is also available as an xPack and can be conveniently installed with xpm:

$ xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc 

To install exactly this version, use:

$ xpm install --global @gnu-mcu-eclipse/arm-none-eabi-gcc@8.2.1-1.1.1
