Hello,
I have some custom hardware based on AT91-ARM7. As an option, the board
may or may not have the network chip (CS8900).
I have the driver working well for this configuration as Redboot is
accessible via telnet, and the tftp load works, also I have run some
of the networks tests.
A problem that I have is that I have not been able to debug via Redboot
and the network connection. When I issue the 'load' command from gdb /
Insight, the load starts (a few packets are transferred), but the load
stops and the board is locked up.
A related issue is that if I try to use the 'network-enabled' Redboot
image, and try to use the serial port to debug, I get the same result-
during the 'load' the transfer stops.
My gut tells me that for some reason Redboot is loosing it's channel
to the built-in gdb stub.
Any ideas on what is going on ? Configuration option that I'm missing ?
Follow on question:
If I remove the network chip (adapter) The network-enabled Redboot
image boots and gives the predictable error that it can't find the network
adapter. If this is the case, I still would like to use serial based
debugging, but this does not work because of the above problem. (I would
think that this should be ok.)
If I build a Redboot image that has just has serial support (sans Redboot
stack), all is happy- with or without the network adapter installed.
Thanks for the help,
-S
