Bare Metal Code Development for iMX8M Mini

We need to write Bare-Metal code for both the core from scratch.

Why not use a certified RTOS? There are plenty with DO-178 certification around (if you need DO-178).

Surely, that has to be preferable to trying to roll your own and then go through the entire  qualification process on that?

Hi Andy Neil Bastian Schick

Thanks for your reply. 

We did explore the RTOS option, we came across QNX. But, this approach demands lots of investment from us. Hence, we want to choose the in-house Bare-metal code development.

Hi Bastian Schick,

Earlier I worked with 'arm-none-eabi-gcc' toolchain for compiling Linux OS. I wanted to know if we can use similar compiler for Bare-metal code development.

My idea is,

- Use Development Studio for initial driver development. Because during this time, we need emulator and other debugging options. So, we can use Design Studio IDE only for 1 to 2 years.

- Once drivers developed switch to 'arm-none-eabi-gcc' (i mean, open source tool-chain)

Our product typically runs for next 15 to 20 years. It is really difficult to pay $6000 subscription for every year for next 15 to 20 years!
