X-SW-Source: 2009-09/txt/msg00229.txt.bz2 Hi, I found some interesting threads (especially one from Martin Laabs=20 called "IRQ-Enable in ARM-Target (cpsr)") dealing with my issue but no topi= c=20 has actually solved it. I want to do remote debugging with GDB. At this point, I have built Redboot= =20 and it starts well and get an IP address from my bootp server. I am also ab= le=20 to ping my host from Redboot prompt. Nevertheless, I can't do the opposite : Redboot does not answer to ping=20 initiated from my host ! However I can tell that ICMP ping request frames a= re=20 well received by my ethernet device (LAN91CXX). But as interrupts are not=20 globally enabled in ARM CPSR register, Redboot does not know anything about= =20 them ! Does Redboot install a listener which poll on ethernet interface ? And wher= e=20 is it done in source code ? Is it possible to enable interrupts in CPSR ? And where is the best place t= o=20 do it ? What configuration option should be activated to achieve such a goal ? I am a little bit stuck at the moment so please any kind of help would be= =20=20 appreciated. Thanks in advance.
