Atmosic board ATM3330

Hi,

I’m wondering if someone is working on these board: https://atmosic.com I’m interested using RIOT on ATM3330. It uses an ARM M33F CPU, is it ported on RIOT?

Thanks,

Never heard of them but it looks interesting.

Any ideas where we can get hardware easily ?

I don’t know, contact them

Do you know if any board uses ARM M33F on RIOT?

Ok, M33F is a M33 + FPU and I see RIOT already includes it

github.com

RIOT-OS/RIOT/blob/master/cpu/cortexm_common/Makefile.features#L16

      
        
            FEATURES_PROVIDED += cpu_core_cortexm
            FEATURES_PROVIDED += dbgpin
            FEATURES_PROVIDED += libstdcpp
            FEATURES_PROVIDED += newlib
            FEATURES_PROVIDED += periph_pm
            FEATURES_PROVIDED += puf_sram
            FEATURES_PROVIDED += picolibc
            FEATURES_PROVIDED += ssp
            
            
# cortex-m33, cortex-m4f and cortex-m7 provide FPU support
            ifneq (,$(filter $(CPU_CORE),cortex-m33 cortex-m4f cortex-m7))
              FEATURES_PROVIDED += cortexm_fpu
            endif
            
            
# Set CPU_ARCH depending on the CPU_CORE
            #
            # RUST_TARGET is only used when building Rust code; any users need to require
            # the `rust_target` feature to esnure things are checked properly.
            ifeq ($(CPU_CORE),cortex-m0)
              CPU_ARCH := armv6m
              RUST_TARGET = thumbv6m-none-eabi

So it should be possible to port the board, Do you agree with that?

100% agree. The big plus would be a JLink or openOCD support for the flashing part.

nucleo-l552ze-q for sure. And I think maybe some EFM32 (or there is a pending PR for it).
