I am using YAGARTO Tool to compile my project based on AT91SAM7X512. I have developed one project without RTOS. Its code size become higher than 265K and ram size around 64K. It works Ok. Now, i want to add TCP/IP. So, that i first make working webserver on my hardware. The TCP/IP Stack which i have used is for AT91SAM7X256. So, i modified every where with AT91SAM7X512 header file with its flash and ram size. The stack which i have used is based on uIP with FreeRTOS. Currently this webserver is working ok. This stack size around 80K. Now, as i mearge this STACK (based on FreeRTOS) with my previous developed project, it stop working after total code size become higher than 265K. I am just adding code. I m not calling any function. As i remove some functions code and as code size less than 264K then it works ok but as it reach limit of 265K, webserver code stop working. I think this problem is created either by STARTUP File or some makefile command which limit code to AT91SAM7X256 flash size. So, How can i solve this problem ?
For refrence i have added below code of boot.s, atmel-rom.ld & Makefile.
