hi,
i m newbee to RTOS, thus to ecos also.i want to port ecos onto my target procesor ARM7TDMI and run GUI application into it.i dont know frm where to start?cud u help me out???i have few silly queries,plz help me..... i had just installed cygwin and tool chain for my target processor.now is that all??ecos has also been installed???i m not sure!.how to check tht?? i am unable to access the cvs repository. my cvs version is 1.11.22.is it the latest one??? steps that are given to access the repository on ecos website is nt working for me.it says"connection failed" every time i give the command.what's wrong??? i have anthony j. massa book on ecos, bt i dont find it of much use and slight complex even.any other book, simple and to the point.plz provide the link. 1 imp quest. my target processor is ARM7TDMI (LPC 2148).hope ecos supports that.now abt the bootloader.is it already installed in ARM or i have to write??? 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!!!

Hi All,
Did any come across this kind of issue with ecos stack. We are having a system running ecos. And we do a icmp ping to that device with size of 32000 from a windows PC, the requests are timed out after sometime we are running of mbufs Any inputs or insights into this?

Hi Saritha,
I've been having the 'out of MBUFs' problem as well. I had not been able to determine why. When my system reports it though it does not recover. I can reproduce your problem as you describe. It only takes about 10 pings for me to see it appear but at least the system does not lock up in this case. ...Laurie:{) > -----Original Message----- > From: ecos-discuss-owner@...

Hi Saritha,
May i know which TCP/IP stack you are using in ecos ? 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.

Hi All,
I'm just about to start a new project with one of the LPC24XX CPUs. I'd looked for but so far not found an eCos driver for the Ethernet part of these CPUs.

Hi Uwe,
Thank you. Much appreciated. I tried lpc24xx and lpc23xx and didn't think it would have been listed as 2xxx as the current processor is an lpc2212 and it does not have Ethernet capabilities.

Hi,
Thanks to all them , who have responded. The issue is resolved. The bsd tcp/ip timers were not working on our code base ( hence the ip-reassembly freeing timer was not kicking in ). We have updated our file from ecos cvs , hence with the patch in ( ecos-2.0--src\packages\net\bsd_tcpip\v2_0\src\ecos\timeout.c ) file our problem is resolved.

Hey all,
I have encountered the same "Out of MBUFs" problem myself several times in the past couple of months and I was able also to simulate it in several ways. I was very happy to read that there is a patch which solves this problem, but I was unable to find it in the ECOS repository. Can someone please guide me to the correct source code? Thanks in advance, Avishay

Hi Avishay,
I am not sure,the problem you are facing is same as ours. 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!
