The GDU module can not work

ameliafeng — Tue, 12 Jun 2018 09:20:59 GMT

Hello,

I am using a PC9S12ZVML12MKH （maskset：0N06E）for a sensorless BLDC application.

When I downloaded the code into MCU and did single-step debugging，the initGDU program cannot work and all of GDU registers cannot be changed. But when the code is downloaded into development board ( S12ZVML-MINIBRD), the GDU registers can be changed. I cannot find some errors in my designed circuit board.

Have you encountered this situation?

Can you give me some advice about it?

Regard.

Hello,

The 0N06E maskset is a prototype. It is probably not compatible with the production versions.

I see S12ZVM_RM_v0.09 has a different register map.

In comparison to the current version v2.11.

Regards,

Daniel

I think different register map is the reason why the GDU cannot work.But I cannot find the way to change the register map through changing .h or .c in the project. How should I do to change the register map?
Thanks a lot.

Now，I am using the reference code of S12ZVML-MINIBRD: S12 MagniV S12ZVM Mini Board for Sensorless Motor Control. The maskset is 1N95G.

Where can I download the reference code of maskset N06E. I did not find the way to change register map.

Hi,
Unfortunately, we don’t have any reference code for this maskset.
But because the MCUs are pin-to-pin compatible, the best option would be to order new samples and replace the old MCU.
