1k memory flash - Program memory reduction

Other Parts Discussed in Thread: MSP430F1101A

Hello guys,

I have a small project that I wrote for the MSP430F1101A (1k flash memory).

unfortunately, after all code optimizations that I could think of my program do not fit to the size of the chip's program memory size.

I am using IAR, and I am compiling C-99 with High level optimization (according to size).

Error[e104]: Failed to fit all segments into specified ranges. Problem discovered in segment CODE. Unable to place 18 block(s) (0x3f0 byte(s) total) in

0x3c8 byte(s) of memory. The problem occurred while processing the segment placement command "-P(CODE)CODE=FC00-FFDF", where at the

moment of placement the available memory ranges were "CODE:fc18-ffdf"

Attached, My code, I will be happy if someone has suggestions for optimizing my code.

Thanks ahead,

Erez Shaul.

There is very little chance that the compiler can further reduce the 2kB object size to 1kB with your existing source code. But it may be possible that you can use a different algorithm or method to achieve the same goal with only 1kB of Flash. In other word, you probably need to use a more memory efficient method and re-write your source code.

Or just use chip with plenty of memory. Especially if it's small-batch product.

Thanks!

I know that, I succeeded to squeeze into 1k finally.

Best,

Erez.
