Hi @VaneB ,

Thanks you so much for the reply.

Actually I am looking for Secondary bootloader for S32K344. Is there any suggestion regarding secondary bootloaders?

Hi @ashokKumar5nxp

What we have are:

The Unified bootloader previously mentioned (no HSE is used), and there is support in HSE firmware. You can download HSE FW and HSE demo app, HSE OTADEMO for A/B Swap from S32K3 Standard Software -> S32K3 Reference Software packages.

Hi @VaneB,

I just have one more question regarding Unified bootloader.

Is that possible to customize this Unified bootloader? Means, can I include some .c & .h files in this bootloader and build it for S32K3 boards?

Regards

Ashok
