I have configured a static IP address both in the board and my PC. I manage to ping from the PC to redboot, but when I try to do it the other way round a get 100% packet loss. I have all the firewalls disabled, an Ethereal confirms the PC receives a ping query and it returns a ping reply, but the board does not seem to receive it. Any idea?

The debugger on your board may take care of the incoming ICMP reply before it reaches your application. I'm not shure, but you might get some note about it if you connect to the debugger. /Johan Salvador Sancha wrote: > Hi > > I am using a Freescale i.Mx27ads development board, which contains an ARM9 > with redboot installed in it.

Is your PC on the same LAN as the ADS board (i.e. no router between them)? Try enabling network debugging on the device running RedBoot. Using 'fconfig', set 'Network debug at boot time' to 'True' reboot and try it again. This will show you what packets are going through the local network stack. -- ------------------------------------------------------------ Gary Thomas | Consulting for the MLB Associates | Embedded world ------------------------------------------------------------ -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss ^ permalink raw reply [flat|nested] 6+ messages in thread
