S32K312 Can we download the same app to any address using bootloader?

[Reyna_pan45]

Hi all

I now need to implement the ability to download the app to any address in the flash section. Therefore, I modified the address of Pflash in the linker file and selected 'Position Independent Code' to generate different bin files, but the generated bin files are still different.

So, can I achieve this function through such operation?

Or can you tell me any way to achieve such a function?

Thank you.

Hi @Reyna_pan45 

I found an article about PIC on embedded systems. Check it, I think you may find it helpful.

Position-Independent Code with GCC for ARM Cortex-M

Also, the following link is an example code for S32K1 devices that could help as a reference.

Hi @VaneB 

I see the  example code for S32K1 devices. but  there are significant differences in the startup file section between K3x and K1x

Is there a example code for the S32K3?

I suggest  to plan to add this example code for S32K3  as soon as possible, so that users can reduce the cost of entry.

Best regards
