Re: [lwip-users] tcp_write() errors on snd_queuelen

[Andrew Foster]

Tim,

Sorry for jumping in on this late in the thread. I've used the TI 
Port(1.3.2) a couple of times on different projects. Typically, I've 
used it in conjunction with FreeRTOS. One thing to be mindful of is 
making sure you have SYS_ARCH_PROTECT defined correctly.

stellarisif_output and stellarisif_transmit must be ran in critical 
sections with both the PBUF structure and the ETH TX FIFO protected. 
Otherwise, the stellarisif_interrupt can come in and modify the PBUF chain.

Again, I apologize if I'm stating the obvious here or things you've 
already ruled out. I wasn't able to find the original post.
