OTA/ Bootloader compatibility

[Gama]

NXP community, 

I am new to a project that requires OTA capability and I want to enquire about some information to help stakeholders make decisions. Here are the chip details: MCU S32k312, SDK_S32k3_S3212_M7 V3.0.0.

My questions are:

1. Could you provide resources For the OTA application for this MCU?

2. May I know what type of bootloader is used for OTA within the NXP MCU is it a Primary Bootloader or a Secondary Bootloader? 

3. Is it possible to use only the primary bootloader for OTA? and what are the challenges if possible?

Hi @Gama 

HSE firmware supports A/B swap. Refer to the HSE Demo Application documentation: C:\NXP\HSE_DEMOAPP_S32K3XX_0_2_40_0\HSE_DEMOAPP_S32K3XX_0_2_40_0_ReadMepdf

NOTE: HSE firmware and Demo Application can be installed from S32K3 Standard Software > Automotive SW - S32K3 - HSE Firmware.

Additionally, you can find the OTA sample codes available for S32K3 devices under S32K3 Reference Software > Automotive SW - S32K3 - OTA Demo.

Also, there are some online trainings related to the topic that you may find useful.
