ARM region CODE is full error

[Mantas]

Hello support Team.

I was developing a code and I came to a dead end. The problem occured when I added a C block with a gcvt function to display floating point number to display it on LCD. I am using an ARM Pro v4 and the target board EB031. If I delete the C block, the code compiles correctly and is succesfully downloaded into ARM chip. The error code I get looks like this:

I tried deleting a big amount of code, couse I thought that the code is too big for the chip, but it didnt help. It happens only when I add a single block of c with the gcvt(FCV_PHI, 8, FCV_PRNTBUFF); And also I tried changing the target chip to one with more memmory, for egzample AT91SAM7S256, and it compiled OK, but it doesnt look to me that the problem is in lack of memmory on AT91SAM7S128.

Any ideas what is wrong?

Hello,

It looks like you are running out of memory on the device. The line of C code you are adding must be referencing a large library which is causing the code size to balloon and take it over the limits of the device.

That makes sence now...

Thank You Ben!
