I have recently upgraded to OpenRTOS v6.0.3 and yagarto gcc 4.4.2 my previous project (ARM7\_AT91SAM7X256\_Eclipse) now works well. Now wishing to use lwip, I’ve chosen lwIP\_Demo\_Rowley\_ARM7. Problem is that on compiling I get these three errors:  
1) rtosdemo.elf section ‘.eh\_frame’ will not fit in region ram  
2) region ‘ram’ overflowed by 200 bytes.  
3)In function ‘\_sbrk\_r’  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; undefined reference to ‘\_sbrk’

When I decreased one of MY buffers to a smaller value the error for #1 became&nbsp; “region ‘ram’ overflowed by -150 bytes”, how can it overflow in the negative?  
Are errors #2 and #3 releated in any way?

Thanks.

The Yagarto home page contains details of how to fix these errors.

Yes, I looked at that before posting, the .eh\_frame error is not that its missing -&nbsp; but that its overflowing!
