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 remove this problem ?
For refrence i have added below code of boot.s, atmel-rom.ld & Makefile.

(You need to be a member of AT91SAM -- send a blank email to AT91SAM-subscribe@yahoogroups.com )

I see you have updated the linker script to be correct for the part with th=
e
larger memory. I don't think there should be any other changes necessary,
so if the rest of the code is the same (startup file, makefile, etc.) then
you should be ok, but evidently no.

How are you programming the flash? Are you using a bootloader or remapping
the vector table?

Richard.

(You need to be a member of AT91SAM -- send a blank email to AT91SAM-subscribe@yahoogroups.com )

I am programming the AT91SAM7x512 using SAM-BA 2.6. After programming the f=
lash I program "BOOT FROM FLASH (GPNVM2)" by click on EXECUTE Command Butto=
n. I think SAM-BA don't have problem. Because my main project size is aroun=
d 267K. Which is ARM Mode base execution. I can run this thing without any =
problem. Now, my purpose is to merge TCP/IP stack (based on FreeRTOS) with =
my code. So, after merging both code it will reach 267K + 80K > 265K. Becau=
se in FreeRTOS base as my code size increase after 265K it stop working.
And other problem I m facing with web server. I have modified uIP st=
ack to run with ENC28J60. In original stack it is using on chip Ethernet mo=
dule. But in my hardware I don't have sufficient i/o so that I have used EN=
C28J60. In original stack, in uip-conf.h file there is=20
#define UIP_CONF_BUFFER_SIZE 1480
for size of long buffer. I need to change this to start webserver. If I do=
n't change this size then I can ping my hardware but I cant run webpage. To=
, make working web server I have to do
#define UIP_CONF_BUFFER_SIZE 65600

This is actually RAM wasting. But without this I am not able to run webpag=
e. I don't think that in run time this much large buffer size required. Bec=
ause in run time around 10 to 20 COMPUTER will be connected with my hardwar=
e through LAN or INTERNET. So, by increasing buffer size I can run my webpa=
ge. But I need to solve this thing because it is consuming RAM which will n=
ot require at run time.
