lpc_ functions are not part of lwIP. You should go to LPC forums to see
what they do and why they report Ethernet frame CRC errors, thing lwIP
does not know and so does not care about.
You seem to be having a memory trashing scenario.
Make sure interrupts do not call lwIP functions, lwIP is
single-threaded, you can basically use it from multiple threads only by
using the netconn and socket API (do you?), but even so, the main lwIP
code is mostly non-reentrant.
By 1.4.x you mean x=?
In 1.4.1, I'm not sure because I've never used NO_SYS=0, you should be
calling sys_check_timeouts() while you wait. There are timers for DHCP.
(You must for NO_SYS=1). Are you ?
