S12Z does nor run when powering again

hbch — Sat, 15 Jul 2017 01:18:40 GMT

I develop a project based on AN4704SW

The code will work only if the emulator is connected and debuging start again.

When the emulator is moved and power again, the mcu can not work.

The MCU is S912ZVML64F1WSK.

The device file is mc9s12zvml128.h

Hi Guoqiang,

By AN4704SW you mean MTRCKTSBNZVM128?

http://www.nxp.com/downloads/en/board-support-packages/MTRCKTSBNZVM128_SW.exe

This software works correctly on my side.

Please check whether you have correctly configured jumper setting per quick start guide:

http://www.nxp.com/docs/en/user-guide/MTRCKTSBNZVM128QSG.pdf

Do you use the default LINIX motor from MTRCKTSBNZVM128 kit?

Did you make any modifications in the code or configuration?

When code runs in special mode and not in normal mode, the most typical reason is incorrect writing into registers with write once condition like CPMUCOP or MODRRx registers.

I hope it helps you.

Have a great day,
Radek

Hi Radek Sestak, the code work if the emulator is connected and debuging start again, so the hadrware is good. I do not use MTRCKTSBNZVM128. My circuit is based on MTRCKTSBNZVM128. My platform is CW10.6.4 and Win7 32bit.

I hate codewarrior! It is the most terrible tool I ever used. There are so many bugs in the codewarrior. And also it becomes more and more unstable and strange behaviors as the version updates. Version 6.3 or 5.2 is better than 10.0 or updated version. Dose anyone give me a suggestion of debug tool to develop S12Z but not codewarrior.

There is some errors in my .prm file which makes _startup code not download to mcu.

Hi Guoqiang,

Thank you for your update and founded root cause.

Ok, I didn’t meet with such issue yet. But I am glad that it works correctly now.

About CW)

The second most used IDE for S12Z is probably Cosmic.

http://www.cosmic-software.com/s12z_des.php

I suppose, that there will be also another option, but I don’t have any experience with such tools.

I hope it helps you.

Have a great day,
Radek
