__no_init keyword replacement in CodeWarrior?

amit_dhand — Tue, 11 Aug 2015 07:18:06 GMT

Hello,

I would like to use __no_init for some variables in CodeWarrior. But unfortunately CodeWarrior doesn't support this keyword. So I would like to know if there is any replacement for this keyword in CodeWarrior.

I am using CodeWarrior 10.6 for mcu s12zvc.

Please support.

Thanks

Amit Dhand

hi Amit Dhand,

I suggest you use NO_INIT qualifier to the RAM section that you don't want be initialized.

NO_INIT: used for address ranges where read/write accesses are allowed. The linker does not initialize memory area defined with this qualifier at application startup. This is useful if your target has a battery-buffered RAM or to speed up application startup.

For example:

SEGMENTS

NOINITRAM

= NO_INIT

0x001000 TO 0x0010FF;

...

the NOINITRAM section is NO_INIT memory area. Variables allocated in this segment are not initialized at application startup.

I will attach a video for you which showcase how NO_INIT works.

can this help you?

Have a great day,
Zhang Jun
