flashing two elf files problem

weipengert — Sun, 28 Jun 2020 03:13:26 GMT

Hi，

when i debug S32K146,i have a problem in flashing process:

i have two elf :bootloader.elf &App.elf

when i flashing either elf , i could erase and flash code normally and software could run immedietely。

but when i flashing both elf files at the same time , S32D could not excute flash process and popup diag: runtimer 216 at ****** , and S32D tips me that could not access memory at address 0x2497c that is the "main" function address + 4bytes.

the diag as show below.

i try everything i can do ,but it could not work.

could you do me a favor？thanks very much.

my S32D version is S32 Design Studio for ARM Version 2.2(Updated latest version).

Hi,

First of all please make sure that bootloader and application do not overlap in the flash memory.

e.g. compare ld files or compare generated map files or srecord where you can easily extract the memory adresses.

If this is the case please adjust the linker command file (.ld) to avoid flash memory overlap.

Hi:

Sliva，as you said ,the flash areas mistake cause the problem.

in the link files ,i tried to erase and flash data into undefined region.

when i cancel the operation ,it could set up correctly.

thanks a lot.
