RE: [U-Boot-Users] U-boot for 8245 boards

Thanks Chris for the message but that isnt the case really. On startup ,typing INFO does give "COP freeze (startup)" but on typing ti gives "trace" and typing go gives "TARGET : entered Debug state " and than typing info Debug entry cause gives <reserved 0>.
thanks Abhishek

I am trying to port U-boot to a customised 8245 board .
For the Initial bring up , I am using a working U-Boot for another very similar board. The problem is that, using BDI 2000 debugger , The telnet Interface reports it to be at reset address fff0 0100 all the time and no amount of ti or go works When I use gdb it also reports it to be stuck there and a step command results in gdb reporting that a stop signal received . I tried setting break points ahead but no use.
The BDI set-up is working as i tried it with working image of vxWorks loader bootrom.
This does not necessarily indicate your setup is correct, which it likely isn't. When you do an 'info' command from Telnet, after typing 'ti' or 'go', do you see "Debug entry cause " COP freeze (startup)? This generally indicates that the 8245 has entered check stop state due to a hardware/configuration/setup/procesor initialization issue. You will have to debug it.

Yes, it likely is the case :)
COP Freeze means that the BDI-2000 was not able to soft stop the 8245 processor, and had to use a hard stop (Freeze command.) The processor is usually not restartable after a COP Freeze.
