About Processor Expert NVOPT NVPROT initialization (MC9S08DZ60)

Nouchi — Tue, 21 Jul 2009 18:07:44 GMT

Hello,

Is there any means to disable variable initialization (NVOPT NVPROT) with processor Expert (CW for MCU 6.2)?

In the CPU bean inspector "security state" and "protected area" are disabled, but PE always generate this:

/* NVPROT: EPS=3,FPS=0x3F */
const unsigned char NVPROT_INIT @0x0000FFBD = 0xFF;

/* NVOPT: KEYEN=0,FNORED=1,EPGMOD=1,??=1,??=1,??=1,SEC1=1,SEC0=0 */
const unsigned char NVOPT_INIT @0x0000FFBF = 0x7E;

which cause some errors messages with the bootloader.

I remove this lines manually, but it's not an academic methode.

Emmanuel

Hello,

could you please specify what kind of bootloader are you using? Could you please post here a project that leads you to getting the error?

Hello,

The bootloader was inspired from the AN2295, but it used the MSCAN08 instead standard SCI.

The boatloader complain about (NVOPT, NVPROT registers) data outside memory application boundaries. And I don't want (and I can't) modified bootloader. Indeed, NVOPT and NVPROT register are set in the bootloader code.

I was looking for a solution to disable code generation for NVOPT an NVPROT registers with ProcessorExpert.

Hello Emmanuel,

currently there is no such option or fetaure in Processor Expert to disable/enable code generation for NVOPT and NVPROT registers. For now as workaround is there the only possibility to disable code generation of whole project using "Freeze Generated Code" menu command (Processor Expert/Freeze Generated Code) and modify the CPU.c file manually.

However I have passed the request of new feature to handle the code generation of NVOPT and NVPROT registers to developers.

Hi again!

My own solution for this problem was to define two static variables with the same name and place them in my own main program. If i have forgot to comment them out in cpu.c, the compiler will throw an error at me :smileyhappy:

Hello Martin and Emmanuel,

requested option has been already supported in Processor Expert V3.08. Publishing this version is scheduled for end of Q2.
