S32 Design studio for Power debug error on MPC5634M

arjunraveendran — Fri, 05 Jan 2018 09:53:33 GMT

I am struggling to run a project on S32DS for Power ver 1.2, build ID: 170613.

I have a single function "sysclk_init" that is called in main. This only initializes the fmpll. there are no interrupts enabled.

When I step through the code, on entering this function an exception is thrown. Depending on "sysclk_init" is called before or after "xcptn_xmpl()" function, different errors are thrown- (console1.png,console2.png)

I am using PE micro USB multilink.

The debugger settings is attached (debug_settings.PNG).

Also attached is the project.

I have gone through the below links, but could not arrive at a solution after implementing the changes mentioned.

Any pointers to move forward?

Any working examples for MPC5634M ON S32 DESIGN studio is available?

Sincerely,

Arjun

Hello,

I tested your use case and I reproduced the same behavior as you described above. Unfortunately, I was not able to find out the root cause, but I think, there is some issue with debugger, because with Lauterbach debugger, the code works correct. There is no reason, why the code should not work.

So, I escalated this issue to application team and now I wait for additional information. Please be patient, I will keep you inform as soon as I have any information for you.

Regards,

Martin

Hello Arjun,

Thanks for the report. The issue is probably located in the startup script file s32e200_mpc563xm_vle.mac:<S32DS_Power_v2017.R1>\eclipse\plugins\com.pemicro.debug.gdbjtag.ppc_1.7.2.201709281658\win32\gdi\P&E\s32e200_mpc563xm_vle.mac

line 63 is missing instruction:

execute_opcode $7C0007A4 ; tlbwe‍

This causes the MMU page for Perpheral registers A is not configured at all and it throws an exception when accessing the registers.

Attached is the fixed script for your convenience.

Hope it helps.

Stan
