Hi. I'm working on optimize work in emac driver for lwip 1.3.0. on lpc2368, with the aim to maximize performance.
Just some questions: 1. do you use freertos? can you send me your sys_arch.c file? i think it acts an important rule from performance point of view 2. did you write driver using emac irq? and irq function uses semaphore or mailbox for lwip task ? 3. can you send me your lwipopt.h? i want discuss about it! 2008/2/2, Josh Rothstein <[EMAIL PROTECTED]>: > > I know this is a common topic on the mailing list, but I wanted to hear > about people's results trying to maximize throughput with lwIP. > > > > I am current running lwIP 1.2 on an Atmel AVR32 UC3 at 66MHz.
