Fill Memory and Global Variable Address Modifier (@address)

axhubner — Thu, 21 Jul 2016 06:44:42 GMT

Hi,

i am using the Global Variable Address Modifier (@address) to place eeprom variables at a specific location like:

const uint8 EEP_LOWER_TEMP @0x100000U = 85;

const uint8 EEP_UPPER_TEMP_MTR @0x100004U = 100;

const uint8 EEP_UPPER_TEMP_LED @0x100008U = 100;

We are using 4 byte aligement in the eeprom to simplify the writing. My question is how to fill the memory

between two variables? In my example i am using a 1 byte variable. The linker generates a section for each variable

witch is excatly as big as the variable. If i am using the linker to fill my whole eeprom i get conflicts with overlapping segments. If i do not fill there will be gabs in the .sx file.

EEPROM

= READ_ONLY 0x100000 TO 0x1007FF FILL 0xFF;

...

EEPROM_PARAM

INTO EEPROM;

is there a solution to combine the global variable adress modifier with the fill comand?

Regards Axel

Hello Axel,

What data do you want to fill between two variable ?

And i think you do not need fill it, it will be 0 , does 0 can not meet your demand ?

If yes, please tell me why do you want fill it .
