S32K36 Disabling Core Feasibility

Nagasahitya — Mon, 17 Mar 2025 09:02:38 GMT

As per the internal block diagram of S32K36 , this controller is having One lockstep core pair and One Cortex-M7 core & one more Coolflux DSP. we are looking for feasibility of below options.

1) possibility of Disabling of Coolflux DSP core

2) possibility of Disabling of second Cortex-M7 core

3) Converting the second Cortex-M7 core in to a lockstep core for the first Cortex-M7 core. so that first Cortex-M7 core will have two lockstep cores.

In our application we would like to use only One lockstep core pair. So we would like to disable the other cores (second cortex core & Coolflux DSP) for aerospace certification.

Hi @Nagasahitya

1. Coolflux DSP core is disabled out of reset. If needed, it can be enabled by Mode Entry module.

2. You can select which core(s) will be enabled out of reset in Boot Configuration Word. Or it is possible to enable or disable specific core by Mode Entry module later in the software.

3. There's no such option, the device does not support this configuration.

Lukas
