HI,

Thanks in advance


What is difference between .elf and .hex and which should be uploaded in controller for first time

[MoD]

Hi,
a .hex file contains only the values for different memories and will be used for programming of the device (e.g. via Memtool).
A .elf file contains, additional to the memory informations, debug and symbol informations which are very helpful for debugging in a debugger.

I am .elf files into controller but after power cycle, controller do't retain their code. Do I have to flash .hex file into it.

Is your code targeting RAM (0x50000000-0x700FFFFF), or flash (starting with 0x8 or 0xA)? If it's running from RAM, that would explain why the AURIX doesn't retain it through a power cycle 😉

Hi

Can you help me how to resolve this problem. I am using lauterbach to flash code.

Hi KDN.

Where is your application - in PFLASH, or in RAM? When you say the controller doesn't retain its code, what address are you looking at to know it's gone?

Do you have boot mode headers set up, so the AURIX firmware knows where to start your application?

Yes flash (starting with 0x8 or 0xA)
