EEprom emulation driver for MPC5604B

朱先生 — Thu, 12 May 2016 07:02:11 GMT

Hi, All:

We used MPC5604B to develop our project. In our planning, Internal data flash could be instead of EEprom. So we downloaded MPC5xxx_EEE_DRIVER.exe from official website.

Then we tried to compile the demo project(in ..\Demos\build\MPC5604P_CW_VLE folder), two errors were displayed in message box as below:

The IDE can't recognize the .vle opcode. But VLE configuration were already be opened.

Is there something wrong with the demo project? how to solve this problem?

If we used the MPC5604P demo code as EEprom emulation driver for MPC5604B, does the ecu can operate normally?

Thanks for your reply.

Hi,

there are two files common for all compilers:

C:\Program Files (x86)\Freescale\EEE_Driver_v1.3.0\MPC5xxx\Demos\src\C90\C90LC_DF\MPC5604P\ intc_branch_table_vle.s

and

C:\Program Files (x86)\Freescale\EEE_Driver_v1.3.0\MPC5xxx\Demos\src\C90\IVOR2_vle.s

It is necessary to change this line in both files from:

.equ COMPILER, GHS

.equ COMPILER, CW

Then it will work.

I didn’t test it but I believe it will work also on MPC5604B. I can see in the source files that it doesn’t touch specific features but rather flash only, so it should work.

Regards,

Lukas

Hi, Lukas:

Our compiler is Codeworrior, not GreenHills. I forget to configure the compiler option in demo code.

I change the code according to your advise, the ecu can normally work. Thanks for your information, very useful.

Regards,

Bryce.
