Hi all, I have a system that consists of a PC host and several connected to it devices (1 to 7 pieces). Each device has a lwIP stack 1.3 ported over to the Blackfin 537. All of them have the same s/w.
The PC Host s/w is a server that waits until the client devices connect to it. All the devices are powered up simultaneously and they connect to the PC Host. My current configuration is 3 devices connected to the PC. The problem is if I use lwIP 1.2 then I can connect and send data across all devices. When I use lwIP 1.3, I am unable to connect to all 3 devices. Sometimes only 2 of them connect. If I disconnect any of the devices and leave the other 2 - then upon power up they seamlessly connect to the PC and work properly. If I connect the 3rd one a minute later - it also establishes a link. In summary, if I power up 3 devices simultaneously, at least one of the fails to establish the communication with the host but anything less than 3 works fine. Note that I can connect to more than 3 clients with lwIP 1.2. Seems there is a bug lwIP 1.3. Thanks, Kaushal
