RE: [lwip-users] ethernet dead if plug to switch .

[Pettinato, Jim]

I'm a bit behind in my perusing of the list, so sorry if you've solved this already.

 

I have found that the major difference between these two scenarios (crossover cable vs. Intranet) is the amount of broadcast traffic that must be handled. Hence, problems when attached to the network are typically at a low level (i.e. the driver). I would look for issues such as unhandled buffer overruns (if you buffer at the ISR level) or pbuf depletion.

Subject: [lwip-users] ethernet dead if plug to switch .

I was using lwip 1.2.0 with FreeRTOS on STR912 and STE-100P PHY.

It works fine if I connect it to my computer using crossover cable . But when I connect to intranet switch , it will dead about 1 ~ 2 hours later . Sometimes it dead 5 ~ 6 hours .

Other tasks are running well .

Does anyone have the same problem ?
