Hi Guys, I have this strange size issue with my app. I was testing my app with the Linux Synthetic target and things work fine. The app does not utilize any hardware specific feature, rather just relies on the availability of 2 network interfaces to do its job (it's lwIP 1.3.1 from Simon).
Now, I want to finally run this app on my AT91SAM7X512 based board. So I did a size comparison to see if it'll fit in the boards memory (128KB). I compiled my app with ecos configured for the at91sam7xek target. $ arm-eabi-size myapp text data bss dec hex filename 127168 5940 45092 178200 2b818 myapp >From this it seems bss + data will fit fine in the 128KB of RAM that I have on the board. Look at the size output for the _same_ app compiled with the Linux Synthetic target: $ i386-elf-size myapp text data bss dec hex filename 103690 7328 8381268 8492286 8194fe myapp The text size of the ARM binary (~127KB) is understandably larger than the i386 one (~102 KB). But how come the data+bss value is so different!?!? The i386 one is more than 8MB! Is this expected? I'm still googling to find the answer.
