Greetings!
We've been running ARM-Linux on Brutus using the Angel monitor to setup
Brutus' virtual memory, page tables, and to download Linux onto Brutus.
Now, we're migrating away from Brutus and onto our own platform which is
similar to Brutus -- SA1100, 2 banks of DRAM, and 1 bank of ROM, and
one serial port for Angel to communicate with the host computer/debugger
(but none of the other peripherals and switches). We're having an awful lot
of trouble getting our ported Angel to work properly on our platform. We've
been able to run our ported Angel on Brutus, but it just seems to hang
somewhere in the middle of the code when we run it on our platform. We've
been monitoring the GPIO 8,9, 20 lines (which are connected to the 2 green
and 1 red LEDs on Brutus) and we are getting similar but not quite identical
waveforms on those lines when we run them on our board.
Are there any tools out there that allow us to query the SA1100 and find
out what's going on (e.g., through the JTAG interface)? Any other
suggestions? Is there some other component that I need on our board to
make Angel and Linux work???
Thanks!
Sandeep.
