0:0 E-0 Linker error: Not enough RAM, what is it ?

[emule]

hi,

atmega32 + mikrobasicavr

when i declare this

dim buftemp as byte[1024]

i have a error message follow


0:0 E-0 Linker error: Not enough RAM

when i use const buftemp as byte[1024] = (0,0,0, ....)

it work but i can't modify buftemp because is a constante

what is it ?

this provide from atmega32 ?

thanks for your response

any idea ?

It appears that you have declared enough variables which have already consumed over 1024 bytes of the Mega32 RAM - there is 2048 bytes available. (Unless you have external SRAM on your board.)
Some of that 2048 bytes is used for stacks and the compiler run-time support, leaving less that 2048 bytes available for your use.

I just created a very simple program;

program ArrayTest

dim buftemp as byte[1024]
dim data, i as word

main:
for i=0 to 1023
buftemp=00
next i
end.

Once compiled the compiler reported that 1154 bytes of SRAM were used and that there are 477 bytes available for use. That equates to 2048 - 1154 - 477 = 417 bytes used for stacks and run-time support.

Or stated another way; I have a total of 1631 bytes available for my program to use. That will likely change on a case by case basis when calling subroutines, library functions, etc.

When you declare the array as const I suspect that MikroBasic places the array in flash where it cannot be modified at run-time.

The array must be in SRAM for you to be able to modify it at run-time.
