S32K34X bootloader reference

bbaskii — Thu, 13 Apr 2023 10:04:43 GMT

Hi, I am looking for bootloader reference design/document for S32K34X for my project. I have example linker files, startup and vector table for my compilers from the example projects. But i want to separate the bootloader and App and place it in different memory segment. Please point me to any documents or example bootloader for S32K34X series. Thanks In Advance, BB

Hi VaneB,

Thanks for the reply. I am looking for vector table and systeminit modules for S32K342 using GHS compiler. It looks different for IAR, GCC and GHS and confusing me. I also referred 11_S32K3xx_Boot_and_Reset_Sequence_Training.pdf which mentioned only IAR and GCC. If you have any other document and .s file please share for reference.

Thanks & Regards,
bbaskii

Hi @bbaskii

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.
