Hi,
we are evaluating Azure RTOS for our next projects based on safety: for our scope, we need to edit a line of the function __tx_ts_new (_tx_thread_schedule.S file of the Cortex M33 port).
Safety certification would be still valid?
Alessandro

Please see Develop secure embedded applications with Azure RTOS and Tech Licensing programs for more details. I'm also enquiring at the moment if there is a possibility on this scenario and update you as earliest. Appreciate your time and patience.

Hi Alessandro, the safety certification does not cover the assembly files (it only covers the 'common' c code), so you are free to modify the asm as you wish. You need to get the assembly files certified with the rest of your application.
