Nick... I'm using the same ftp... and the same processor... I wrote sftp but it's actually ftpd, from toelke. Some confusion... your board, your design, is an FTP server? You are pushing files from a PC client to an embedded server. I'm assuming no OS... raw, in other words. Do you have the

[lwip-users] Server TCP RST prevents client code from draining the receive buffer.

Hi all, We've encountered a couple of interesting http servers in the wild that redirect, then send a TCP RST immediately. Some http servers do this to avoid the TIME_WAIT state. Viz: https://support.microsoft.com/en-gb/kb/272933 In our case, the data for the redirect appears to make it into

Re: [lwip-users] TFTP init

What ftp library are you using? I successfully used sftp with lwip 1.4.1 and fatFS, no OS needed, to be an FTP server for an SD card. Are you being a server or a client? Sounds like client. Pretty sure all the ftp things need a file system to work. Using a file system is going to be

Re: [lwip-users] TFTP init

I guess you need to check memory configuration. How much RAM do you have? Are you using memory pool or malloc? One thing to note here, I have written modified vfs layer for both my systems as none of them use FatFS. I don’t know if that will have any impact as such. You better check your lwIP

[lwip-users] Problem with sending UDP packets in LwIP & FreeRTOS

Hello I work on a project which use FreeRTOS and Lwip v 1.4.1. I'm using a LandTiger board which is made on an NXP LPC1768. My project is based on LPCOpen 2.10 and derivated from the “lwip_tcpecho_freertos” example. I'm only using the Socket API. In TCP, everything is OK! but in UDP doesn't...
