BSP's and bootloader are same or diff????? i have to interface graphical LCD to my processor.which LCD wud be compatible to ARM7TDMI, its no. and do i have to write driver for that or i cud get that directly frm u all??? what u say!!! plz help me out man!!!

But I would like to give you the description of our issue and the fix details. Due to the limitation in our ethernet driver (resources) we drop some of the IP fragments.( ICMP or ping packets (ping > 16K) which is IP fragmented).Due to the drop, remaining IP fragments remaining in the IP re-assembly queue and were not getting freed up. ( They are sitting in the re-assembly queue). This resulted in the leak of Mbufs in the eCos. The reason for above is that - The re-assembly timer was not working. Fix for that was done in the bsd timer as mentioned below by taking the patch from eCosCVS (latest version) With the below patch, the timers are working, hence the re-assembly queue gets flushed,mbufs leak is fixed. /////////////////////////////////////////////////////////////////////////////////////////////// 106c106 < e = _timeouts; --- > e = timeouts; 266a267 > int i; 275c276 < for (e = _timeouts; e; e = e->next) { --- > for (e = _timeouts, i = 0; i < NTIMEOUTS; i++, e++) { 295a297 > int i; 299c301 < for (e = _timeouts; e; e = e->next) { --- > for (e = _timeouts, i = 0; i < NTIMEOUTS; i++, e++) { 404a407,409 > // the following triggers if the "next" timeout has not just > // passed, but passed by 1000 ticks - which with the normal > // 1 tick = 10ms means 10 seconds - a long time. 406c411 < "Recorded alarm not in the future!" ); --- > "Recorded alarm not in the future! Starved network thread?" ); //////////////////////////////////////////////////////////////////////////////////////////////// I would suggest that you need to figure out , where exactly the mbufs are getting leaked or getting held-up in your case.

Even through i did not work with ecos. I did couple of projects with lwIP and uIP stacks. If it is lwIP TCP/IP stack look at the opt.h file and try to increase buffer size and change that in lwipopt.h. I cannot think of anything at this point. Unless in know which stack you are working with. Kishore Saritha Yellanki wrote: > Hi All, > > Did any come across this kind of issue with ecos stack. > > We are having a system running ecos.
