Could you please inform me about the current status of getting tftp running with lwip? Has any of you done some work on it? My problem is that I need tftp, but I have not much RAM (1MB, but jffs2 alone eats half of it). This are my options: 1- I could try getting tftp work with lwip 2- I could try reducing the RAM usage of freeBSD, e.g. by removing tcp from it (I don't need tcp) 3- On the lwip-users archive, there are also some mails about an *FTP server* for *lwIP*, but nothing 'official', and anyhow, then I still would have to port it to ecos. I will start with that what runs now: option 2. Any help about the options is of course appriciated ;-) Kind regards, Jürgen Lambrecht -- Jürgen Lambrecht Development Engineer Televic Transport Systems http://www.televic.com Televic NV / SA (main office) Leo Bekaertlaan 1 B-8870 Izegem Tel: +32 (0)51 303045 Fax: +32 (0)51 310670 ---------------------------------------------------------------------------------------------- Re: Help regarding:installing tftp-hpa on ecos, using lwip instead of the default tcp/ip stack??? * /From/: Durgaprasad Chivukula * /To/: jani at iv dot ro * /Cc/: ecos-discuss at sources dot redhat dot com * /Date/: Wed, 13 Jul 2005 15:29:34 +0200 * /Subject/: Re: [ECOS] Help regarding:installing tftp-hpa on ecos, using lwip instead of the default tcp/ip stack??? * /References/: > <1121170114.5931.44.camel@hermes > > * /Reply-to/: Durgaprasad Chivukula ------------------------------------------------------------------------ Hi , Please reply , if you guys have any idea about my problem . 1. Whether I can configure ecos and the tftp client & server packages inside the ecos to use lwip (low weight ip ) instead of the default tcp/ip stack ??? 2.If its possible , please tell me how can I accomplish this .????

I think the reason is that the "NET package" is ecos is/was synonimous with 'one of the BSD derived stacks'. tftp sntp httpd microwindows and other network code were written to work with the bsd stacks. Making them work with lwip would mean doing: 1) all the cdl work to at least allow them to be selectable together and separating the idea of TCP/IP and BSD socket from the specific implementation.(2 years ago the first such change was adding a config option to mean interrupt support in eth drivers != CYGPKG_NET) so lwip could work in interrupt mode 2) where lwip can not handle the features requested (there are many still missing) implement those. step 0 would be including lwip in CVS so there's a codebase people can base their patches on. Of course they can do it against savannah but since it's not 'offcial' it tends to encourage quick private hacks instead of clean solutions.

I have seen questions/posts about running ppp on an eCos target, but that's overkill for what I want. Basically, I am looking for the inverse of the "load" command in RedBoot, with x/ymodem support. You can save a buffer in memory on the target using GDB 5.3 if that's all you're interested in. Otherwise TFTP server including IP stack is all there is, although you could try running it on top of LWIP rather than beefy BSD TCP/IP.
