nRF5340: Compiling nrfx drivers with different compilers

[dani_martin]

Hi

we are using nrfx drivers for nRF5340 with gcc-arm-none-eabi and they work great. Now we are planning to move to another compiler and I have a couple of questions:

* IAR

I've seen many "if defined ( __ICCARM__ )". Are these drivers fully tested with this compiler? Any document/info about it?

* Keil, Green Hills

We are also evaluating other compilers. Any other information, experience with them?

Thanks!

dani_martin  May I ask about your toolchain? Do you use any IDE or just make with gcc? Was the linker script in nrfx/mdk working out of the box? Thank you in advance

hi, we have a cmake based project, with arm-none-eabi-gcc compiler, and with that compiler the linker scripts work perfectly.   

Now we are considering a migration to a different compiler (we are evaluating different ones) and thats why I'm interested in the support for them. The compilation of the drivers is one issue and the linker script is another issue, as you know. I'm indeed right now trying to convert nrf_common.ld to a scatter file for clang.

Any experience with clang?

I only have experience with the Segger IDE in terms of NRF stuff.  But the MDK has an example scatter file in it for the nRF5340: https://github.com/NordicSemiconductor/nrfx/blob/master/mdk/nrf5340_xxaa_network.sct Maybe you could use this?

My goal is to run an NRF5 SDK + FreeRTOS + radio (not BLE) app on the NRF54L15 instead of the NRF52840. So I thinking about using GCC either with cmake or some IDE + the FreeRTOS port for Cortex-M33
