Maybe your sys_now() or sys_jiffies() functions are too course? They should have a resolution of approx. 1 msec. But depending on your hardware it could not be so easy to accomplish. BTW, what is your hardware? I've myself built with NO_SYS=1 on djgpp/MSDOS with no long delays as you describe. Hence I think it's a problem with your 'clock-tick' function. -- --gv _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
