Hi Alessio,
meta-arm have some binary baremetal toolchains for arm and aarch64 at:

its possible to build baremetal toolchains, e.g. look at meta-riscv
baremetal machines e.g.
https://github.com/riscv/meta-riscv/blob/master/conf/machine/baremetal-riscv32.conf
you can do
MACHINE=baremetal-riscv32 bitbake meta-toolchain
Which will give you a toolchain, but if you want more like what we can
do with MCU OSes like freertos and zephyr take a look at
meta-zephyr (https://git.yoctoproject.org/meta-zephyr/) and
meta-freertos (https://github.com/aehs29/meta-freertos)

Dear Yocto developers,its possible to build baremetal toolchains, e.g. look at meta-riscv baremetal machines e.g.
Is there a way to generate an SDK which contains the toolchain for
bare-metal systems (i.e. MCU without operating system)?

Hello Alessio,
However, define what you mean by SDK? Which libraries or programming
languages are you thinking of beyond the C library for example?

Have you had a look at crosstool-ng?crosstool-ng is mostly the toolchain, I would not consider this an SDK
beyond that.

Hi Alessio,
Have you had a look at crosstool-ng?
Best regards, Laurent.
