Firmware for USRP2 simulation testbench

GNU Radio

Is there a firmware image optimized for the USRP2 simulation
testbench? The README in fpga/usrp2/testbench mentions an
eth_test.rom whose source doesn’t seem to be anywhere (except an old
snapshot of the repository in trac that Google finds).

From the verilog it seems you would want the hal_ routines to use the
UART for output, then do the magic write to 0xC2F0 in hal_finish(),
but hal_io.c only does the magic write in hal_finish when using the
dboard gpio pins for output. So maybe another hal option is needed?
It also seems like you could make a .rom that was much smaller for
simulation (simulating the loading of the 50+k of mostly dboard
related code into the RAM takes a while and isn’t really necessary
since the dboard isn’t simulated).

Just wanted to make sure I wouldn’t be reinventing the wheel before
embarking on writing my own firmware stuff for simulation…

Thanks,

Jared

You need to choose one which exercises what you want to test.
blink_leds is a good one to make sure everything is working.
